1 General informations
Press-Right is a control and measurement instrument which, when connected to a press, guarantees the
quality control of the production processes.
Interfaced to a position transducer and a load cell, it continuously detects the position and the instantaneous
force.
1.1 Introduction to control theory
During machining on sample pieces, the data relating to the position of the cylinder and the force exerted by it
are recorded; the graph can be drawn: position-force which is characteristic of the work carried out.
If several machining operations are carried out on similar pieces, the respective position-force curves will also
be similar. If, on the other hand, one of the workpieces differs from the sample, the relative curve will deviate
from the sample curve. It is intuitive how curve control can ensure consistent machining quality.
1.2 Control of the position-force curve
From a theoretical point of view there is an ideal curve which is obtained by machining perfect pieces (in
practice there may be a sample curve obtained by machining carefully selected pieces). Any geometric
tolerances or material differences lead to a deviation from this ideal curve.
In practice, the Press-Right controls the curve through a tolerance range, check points and limits.
The tolerance range positioned around the sample curve is such that if the curve obtained from the current
machining does not pass within this range, the piece is rejected.
The limits control the position and the force values reached. The limits are as follows: minimum peak force,
maximum peak force, minimum peak position and maximum peak position. If the position reached does not
exceed the minimum peak position and/or exceeds the maximum peak position, the piece is rejected. In the
same way, if the force reached does not exceed the minimum peak force and/or exceeds the maximum peak
force, the piece is rejected.
The check points are used to control the curve in discrete points, for example it is possible to check that in a
pre-established position the measured force is between a minimum and a maximum, or that at a pre-
established force the measured position is between a minimum and a maximum. If the values measured in a
check point are not correct, the piece is rejected.
1.3 Absolute and relative odds
The positions referred to the zero of the cylinder are called absolute positions. The positions referred to the
contact position on the piece are called relative positions. The Press-Right can use both absolute and relative
positions. The load cell is used to detect the contact position: when the force measured by the load cell exceeds
a programmed value, the position values is set to zero. This force value is called CONTACT DETECTION
THRESHOLD. The position in which the contact is detected (contact position) is recorded and can be
controlled with two limits, minimum and maximum, to continue or not.

1) Top dead centre
2) Zero absolute position
3) Zero relative position
Figure 1
The accuracy of the contact position detected with the load cell depends on the speed of the cylinder and
above all on the type of piece to be machined. In inserting operations, the two pieces have rounded corners,
consequently the contact position also varies with the variation of the bevel and the force used to position one
part into the other.

2 Installation Press-Right
To install the instrument on the machine, consult the specific manual.

3 How to start
This chapter will walk you through the basics of programming and using the Press-Right instrument.
To better illustrate the operations, it is advisable to carry out the tests in practice; to do this it is very useful to
have an elastic support of adequate compliance to simulate repeated machining.
Figure2
To turn on the instrument there is a button on the back. When it is pressed, after a few seconds, the display
lights up and the graph appears.
3.1 Press-Right user interface
If you touch the menu button, the items that make up the main menu are displayed. To select an item in the
menu it is possible to move with the arrow keys and press the OK button or it is possible to directly touch the
item itself.
The RESET button cancels the operations and allows you to return to the main screen.
3.2 First approach
A few seconds after being switched on, the display lights up and shows the main screen. The main screen
displays the graph area and below it the values measured by the connected transducers.
First let's create a simple job:
•Touch the menu button
•Touch the JOBS LIST item
•Touch the CREATE A NEW JOB item
•Enter the name that identifies the job (example TEST 1) and press the enter key.
Note: in the rest of this manual, when it is indicated, for example, “JOBS LIST > CREATE A NEW
JOB” command, we mean to press the menu button, then press the JOB LIST item and finally press the
CREATE A NEW JOB item.

9
Once the job has been created, indicate to the instrument when it has to stop the press by entering a stop
value. The stop value can be a position value or a force value. The difference in usage is explained in chapter
5. Press EDIT JOB > STOP VALUES > STOP FORCE, enter a value lower than the maximum force that the
press can exert and confirm.
By giving the machine start command, the press will advance and will exert a force that will increase up to the
stop value that we entered previously.
If a too high stopping force value has been entered, the press will continue to push; to stop the press manually,
press the RESET button. In this case the piece is rejected because the work has been interrupted.
3.3 Set the view
The central part of the display is occupied by the position-force graph. It is possible to modify the full-scale
values using the commands in the EDIT JOB > GRAPH SETUP.
3.4 The main menu
Note: Some menu items are not visible if not needed.
The main menu is the first displayed by pressing the menu key.
JOBS LIST allows the choice of the job to be used, the creation of a new job or the elimination of the job in
use.
The PHASE EDIT is visible when the job is divided into several phases. It allows the modification of all the
parameters of the displayed phase.
The EDIT JOB allows you to modify all the parameters of the job in use. See chapter Errore. L'origine
riferimento non è stata trovata.. When the job is divided into several phases, the modification of the
parameters of the single phase will be possible from the PHASE EDIT menu while the options common to all
phases will be present in the JOB PROPERTIES menu.
The SHOW MEASURED VALUES displays the values measured during the last cycle.
The TOOLS allows the modification of the instrument configuration and the possibility of moving the cylinder
manually.
The item RESET COUNTERS is used to reset the counters of processed pieces. When the batch number is
managed, this menu will be replaced by the NEW PRODUCTION BATCH menu which allows the batch
number to be entered. This number will be stored together with the curve.
The PART NUMBER item allows the insertion of the identification number of the piece being processed. This
identifier will be stored together with the curve.
The USER item allows the operator's identification to be entered. This identifier will be stored together with the
curve.
The PHASE TO EXECUTE item allows you to select the next phase to be executed by modifying the normal
execution sequence. When a phase runs out of sequence, immediate stops on reject are disabled. This
command is available only if the phase sequence is adjusted by the instrument.

10
4 Jobs
The Press-Right memorizes all the settings (parameters, tolerance range, limits and counters) relating to the
various jobs in an internal memory. Each group of settings is called Job. Each job has its own name.
JOBS LIST item is present in the main menu. Through this menu it is possible to choose a job among those
present, create a new one, or delete the job in use.
4.1 Create a new job
To create a new job, use the JOBS LIST > CREATE A NEW JOB and give it a name. As a name you can use
the drawing number, the customer's name or whatever you prefer to be able to easily identify it.
When creating a new job, you are asked if you want to make a copy of the job currently in use. If you choose
to copy the current job, the parameters of the current job will be duplicated and will remain unchanged. In the
other case the new one will be empty.
After having created the job, you can set the parameters, options and tolerance range.
4.2 Change the job name
To change the name of a job, you must first select it. Once you have selected the job to which you want to
change the name, you can use the command EDIT JOB > PROPERTIES AND OPTIONS > NAME OF THE
JOB.
4.3 Selecting a job
SELECT JOB command is present in the JOBS LIST menu. When this command is selected, the list of jobs
present is displayed. The date and time the job was last modified is shown next to the name.
If the list is very long, look for the name by touching the magnifying glass icon.
To prevent manual selection of a job, the selection of jobs can be locked with a password. To activate the
password, activate the Job selection option in the TOOLS > PASSWORD > FUNCTIONS WITH PASSWORD.
4.4 Selection of a job by barcode
If a barcode scanner is connected, it is possible to select the job automatically by simply reading the barcode.
To activate this function, activate the Jobs with identification codes option in the TOOLS > SETUP > JOB
SELECTION.
After activating the Jobs with identification codes option, the relative identification codes must be assigned to
the jobs. To assign the codes to the job see chapter 4.7.
4.5 Selecting a job via tool recognition
It is possible to connect sensors and RFID antenna to the instrument to automatically recognize the tool used.
It is possible to recognize up to three parts, for example the punch, the placement, and a simple mechanical
selector. These signals can be used to automatically select the job to be used or to enable machine operation.
To activate the recognition of the tools, the relative options must be configured in the TOOLS > SETUP >
ELECTRICAL CONNECTIONS > TOOLS.
After having configured the recognition of the tools, it is necessary to activate the automatic selection in TOOLS
> SETUP > JOB SELECTION. Finally, the relative tool code must be assigned to the jobs in EDIT JOB >
PROPERTIES AND OPTIONS > ACCESSORIES.

11
4.6 Selection of a job via fieldbus
It is possible to select the job to be used via the fieldbus in three different ways: via the job name, via the
identification code or via an index number.
4.6.1 Selection from fieldbus by name
To select a job, first write the code of the desired job in the string buffer at the address 45, then write command
3 in the CONTROL_WORD_OUTPLC.
4.6.2 Selection from fieldbus via the identification code
To activate this function, activate the Jobs with identification codes option in the TOOLS > SETUP > JOB
SELECTION.
After activating the Jobs with identification codes option, the relative identification codes must be assigned to
the jobs. To assign the codes to the job see chapter 4.7.
To select a job, first write the code of the desired job in the string buffer at the address 45, then write command
2 in the CONTROL_WORD_OUTPLC.
4.6.3 Selection from fieldbus by index number
To activate this function, activate the Jobs selectable by index option in the TOOLS > SETUP > JOB
SELECTION.
After activating the Jobs selectable by index option, the relative index number must be assigned to the jobs
in EDIT JOB > PROPERTIES AND OPTIONS menu.
To select a job, write the index number of the desired job in register 90.
4.7 Modify job identification codes
To assign the codes to the job, first select the job and then go to the EDIT JOB > PROPERTIES AND
OPTIONS menu. Depending on the configuration, it will be possible to enter the identification codes and the
identification number of the equipment. Up to seven codes can be assigned to each individual job.
Notes:
When the code entry window is displayed, you can use the barcode reader to automatically enter the job
identification code.
If an @ is inserted in the code, this character will be ignored in comparison with the read code.
4.8 Copy a job
To copy a job, it is first necessary to select the job to be copied; once the job to be copied has been selected,
the new job must be created using the JOBS LIST > CREATE A NEW JOB command and, when asked to
copy the job, answer YES.
4.9 Delete a job
To definitively eliminate a job from the instrument's memory, select the JOBS LIST > DELETE JOB command.
4.10 Edit a job
The EDIT JOB menu allows the modification of all the parameters that make up the job. If the job has several
phases, in this menu it will be possible to modify the parameters common to all the phases while the
modification of the parameters of each single phase will be possible from the MODIFY PHASE menu.
Note: In general, in jobs, the parameters set equal to zero will be ignored by the instrument.

12
4.11 Job counters
Each job has a piece counter. To access the counter options, select the menu EDIT JOB > SCHEDULING.
In this menu it is possible to reset the piece counter or choose a maximum number of pieces to block the
instrument.
4.12 The graph
The submenu GRAPH SETUP allows you to modify the values of the graph axes to enlarge and show the
interesting part of the position-force curve.
Auto range
This function adapts the scale of the graph to display the curve of the last machining performed.
Graph origin
It is the origin value of the horizontal axis of the dimensions, this parameter allows you to hide all the run
of no interest, such as the approach run. If relative dimensions are used, the origin should normally be
set equal to zero.
End scale position
The full scale of the positions indicates the maximum stroke which is displayed in the graph.
End scale force
The full scale of the forces indicates the maximum force that is displayed in the graph.
4.12.1 How to set up the graph
After executing a piece, it is possible to view the measured values. From these it is possible to obtain the
values of the graph axes.
As the origin of the graph, enter a value slightly lower than the measured starting height. As end scale of the
positions, enter a value higher than the measured position reached.
As end scale of the forces, choose the value higher than the measured reached force.
For convenience, the values measured in the last pressing are shown in the value entry box.
4.13 Phase management
It is possible to manage multiple processing phases for a single job. The phases can be considered as "under
construction" which contribute to the completion of a more complex process (for example the insertion of a
bearing and a gear on the same shaft).
The phase management functions are normally hidden. To make them visible, select the Job phase
management option in the TOOLS > SETUP > VISIBLE OPTIONS menu.
To use more phases, it is necessary to enable the execution of phases in the menu EDIT JOB > ENABLE
PHASES. Once you have enabled the phases, you can change their name.
When a job has several phases, the main menu will contain the PHASE EDIT item where it is possible to set
all the parameters of the displayed phase and the JOB PROPERTIES item where it is possible to set the
options common to all phases. In this manual we will continue to indicate the location of many commands in
the EDIT JOB menu but if we are using phases, the same commands will be in the PHASE EDIT menu.
The list of phases is always visible in the upper part of the graph, with the keys it is possible to change
the phase displayed and modify its parameters with the PHASE EDIT menu. The phase that will be performed
is always indicated at the bottom right of the main page. Changing the phase displayed with the arrow keys
does not change the phase that will be performed. To change the phase to be executed it is possible to touch
the phase name at the bottom right or use the PHASE TO EXECUTE command.

13
The phases will be performed automatically in sequence. If you want to carry out a phase individually out of
sequence, select the Do not perform the phases in sequence option in the TOOLS > SETUP > JOBS
SELECTION menu. In this case it is not possible to change the phase that will be performed from the menu.
It is also possible to have a single phase repeat several times by activating the Phase repeat options in the
TOOLS > SETUP > VISIBLE OPTIONS menu.
4.13.1 Phase copy
To copy a phase, you can use the COPY PHASE and PASTE PHASE commands in the PHASE EDIT menu.
The copy phase command stores the current job number and the current phase number. The paste phase
command overwrites the current phase with the job phase stored with the copy phase command.

14
5 Parameters
After creating a new job, the first thing to do is to set the job options in the EDIT JOB > PROPERTY AND
OPTIONS menu.
Once this is done, it is possible to set the operating parameters.
Note: In the jobs the parameters set equal to zero will be ignored by the instrument.
5.1 Stop values
The first thing to do is tell the instrument when to stop the press. To set the stop values, use the EDIT JOB >
STOP VALUES menu.
The Press-Right can stop the press when the force reaches a certain value (Stop force) or when the press
reaches a certain height (Stop position).
Note: The press is also stopped when the maximum acquisition time expires.
5.1.1 Notes on stop values
When both the stopping force and the stopping position are set, it is sufficient to exceed one of the two to
command the stop.
It is normal to detect values reached higher than the stop values; this is due to the intervention delay of the
electromechanical parts.
It is possible to continue pressing when the stop values are reached for a pre-set time. To set the press stop
delay time, use the STOP VALUES > STOP DELAY.
5.1.2 How to choose the stop values
The stop must be set differently depending on the type of machining. Three types of processing can be
distinguished:
1) Full shrinking, chamfering or work up to a mechanical stop.
2) Work up to a position (without mechanical stops).
3) Bending and breaking test.

15
5.1.2.1 Stop with mechanical stop.
In most cases the press is used to carry out an insertion up to a mechanical stop. In this case the curve will be
similar to that in next figure, i.e. the force will be zero for the entire approach stroke, once the piece has been
reached (at the contact position) the force will begin to increase until the mechanical stop is reached where it
will increase up to the maximum force value of the press (vertical part of the curve).
Stop force must be used as the force will always reach the maximum that the press can exert. If we used the
stop position this could not be reached if the piece is slightly higher than expected or it could be reached even
before completing the job if the piece is too low.
The stop force must be chosen such as to guarantee the completion of the machining.
The stop force must be less than the breaking force of the workpiece or the tool.
The stop force must be less than the maximum force the press can exert.
5.1.2.2 Stop without mechanical stop
It is possible to stop the descent of the press rod at an established position by setting the stop position. In
this case the instrument will switch the valve which controls the descent of the press as soon as the stop
position is reached. This valve will take some time to switch and more time will be necessary before it begins
to evacuate the pressurized air in the cylinder: for these reasons, the real stop of the press will be at a higher
level than the set stop value. This error will be greater the higher the descent speed and the greater the
difference between the force required to do the work and the force of the cylinder.
5.1.2.3 Stopping during a bending and breaking test
The force that the piece under test must resist is used as the stop force. In the event of breakage, the stopping
force will not be reached, therefore it is also necessary to set the stop position value equal to a value that
cannot be reached without breaking the piece.
If the piece resists the stopping force, once the test is over, the reached position will be equal to the bending
that the piece has had. It will then be possible to verify whether the deflection obtained is the one expected
using the position limits.
If the piece breaks before the impact force is reached (next figure), at the end of the test, the reached force
will be equal to the breaking force of the piece.
To verify that the piece has not broken and has withstood the force required, it is necessary to enter the
minimum force limit equal to the stop force value.

16
5.2 Control limits
The control limits, together with the range, determine the outcome of the job.
It is possible to set the limits of the reached force, the limits of the reached position, the limits of the contact
position and the check points.
Note: Control limits, set equal to zero, are not used.
Contact position limits
They control the contact dimension of the working. For a part to be classified as good, the measured
contact dimension must be above the minimum contact dimension limit and below the maximum contact
dimension limit.
Peak Position limits
They control the maximum position reached during machining. For a piece to be classified as good, the
measured position reached must be higher than the minimum position reached limit and lower than the
maximum position reached limit. If the minimum reached position limit is not set and the tolerance band
is present, the position of the band is used as the minimum limit.
Peak Force limits
They control the force reached during machining. For a piece to be classified as good, the maximum force
achieved must be above the minimum force limit and below the maximum force limit.
Contact detection threshold
The initiation force is the force threshold used to measure the contact height.
5.2.1 How to choose the limits
Contact dimension limits let you control the dimensions of components even before the job begins. They can
be used to check the dimensions of the pieces to be assembled or to check that there are all the details
necessary for the machining.
The choice of the limits of the position values and of the force reached depend on the type of machining. In
general, you can follow this guide:

17
Limits with machining with mechanical stop
When there is a mechanical stop, the press will always reach either the stop force. The maximum peak force
limit can be used to ensure that the maximum force that the workpiece can withstand is never exceeded.
In this type of work, to control the effective force required, the tolerance range or the checkpoints are
necessarily used.
The peak position limits are used to verify that the dimensions of the assembly, once machining is completed,
are within tolerance.
Limits with machining without mechanical stop
The peak force limits can be used to control the maximum force that has been applied to the workpiece.
The peak position limits are used to verify that the dimensions of the assembly, once machining is completed,
are within tolerance.
Limits for bending and breaking tests
In bending tests, the force limits are used simply to verify the force that has been applied while the position
limits are used to verify the measured deflection.
In breaking tests, force limits are used to verify the force that was required to break the piece.
5.3 Checkpoints
Checkpoints are additional tools for curve control. Up to five checkpoints can be defined. Each checkpoint can
be used to:
Check force
Measure and control the force at a pre-set position. This check point is also useful for having a discrete
value at the end of pressing to be displayed or sent via fieldbus.
Check position
Measure and control the position at a pre-set force. This check point is useful for checking deformation at
a pre-set load. It is also useful to have a discrete value at the end of pressing to be displayed or sent via
fieldbus.
Digital force filter
This check point is useful to clean the curve from unwanted vibrations.
Minimum maximum measurement
This check point is useful for having the minimum and maximum force value in a section of the stroke to
be displayed or sent via fieldbus.
Slope control
This check point measures the force at the check position and at a certain distance verifies that the force
variation is between a minimum and a maximum.
Localized stop
This check point commands the cylinder to stop when a pre-set force is reached. The force control takes
place only in a pre-established section of the stroke. The stop can take place as soon as the force is
exceeded or after a pre-set stroke.

18
6 Job options
The following job options can be modified with the EDIT JOB > PROPERTIES AND OPTIONS > OPTIONS.
If the job is divided into several phases, the options relating to a single phase are found in the PHASE EDIT >
PROPERTIES AND OPTIONS menu, while the options relating to the whole job are found in JOB
PROPERTIES.
Use relative positions
By activating this option, the relative positions are used instead of the absolute ones (chapter 0).
Request batch ID
By activating this option, before running a batch, you are asked to enter a batch identifier. To use this
option, you need to activate the Lot id management option in the TOOLS > SETUP > VISIBLE OPTIONS
menu.
Ask for the piece code
By activating this option, before executing each piece, you are asked to enter a numerical code that
identifies the piece itself. The piece code can also be set via a barcode scanner. To use this option, it is
necessary to activate the Part number management option in TOOLS > SETUP > VISIBLE OPTIONS
menu. Contact Alfamatic to find out which barcode readers are compatible with the instrument.
Save curves of pieces good
Save the curves of the good pieces on the internal flash memory.
Save curves of pieces rejected
Saves the curves of the rejected pieces on the internal flash memory.
Do not use rejected basket
Disables basket control for rejected pieces.
Request a confirmation with rejected
By activating this option, when a phase is recognized as reject, a message is shown which allows you to
confirm the reject, repeat the reject phase or move on to the next phase. To use this option, you need to
activate the Request a confirmation with rejected phase option in the TOOLS > SETUP > VISIBLE
OPTIONS menu.
Ask for the operator code
By activating this option, you are asked to enter the operator ID. This identifier will be stored together with
the curve. To use this option, you need to activate the Operator ID management option in the TOOLS >
SETUP > VISIBLE OPTIONS menu.
6.1 Counters
Through the EDIT JOB > SCHEDULING command it is possible to configure the counters and the data saving
and maintenance options.
There is a counter for good pieces and two counters for normal and special pieces. There is also a counter
that counts the number of cycles performed with a single tool. Finally, it is possible to enable the saving of the
curves in the internal memory of the instrument. To transfer the curves, it is necessary to connect the
instrument via the LAN port and use the Alfamatic AutoCopy program.
Reset the number of good pieces
Resets the counter of the number of good pieces made.
Reset the number of rejected pieces
Resets the counter of the number of rejected pieces.
Save curves
Activates the saving of the curves in the internal memory of the instrument.
Save a good curve every

19
If you only want to save some curves, with this parameter you can set every how many pieces you want the
curve to be saved.
Number of good pieces to be produced
Number of pieces to produce. When the good parts counter reaches this value, a warning appears on the
instrument screen.
Maximum number of rejected pieces
Maximum number of rejected pieces, once this number is exceeded, a warning appears on the instrument
screen.
Tool life
Number of pieces that can be made with the same tool, once this number is exceeded, a warning appears on
the tool screen.
If a tool is shared among several jobs, it is possible to activate the Shared tools table option in TOOLS >
SETUP > ELECTRICAL CONNECTION > TOOLS > "THIRD TOOL". With this option active, a table of twelve
tools is created which can be shared between several jobs. The table is visible in the TOOLS >
MAINTENANCE menu. To indicate in the job which tool in the table must be used, access the EDIT JOB >
PROPERTIES AND OPTIONS > ACCESSORIES menu.

7 The tolerance range
The tolerance rage is used to control the curve and consequently to control the quality of the piece.
The tolerance rage consists of two lines called the upper border and the lower border.
For the piece to be classified as good the points representing the curve cannot be above the upper edge, and
cannot be below the lower edge.
The figure shows a curve relative to a good piece, as it is included between the two edges of the tolerance
range.
Figure3
Each border is composed of a sequence of points joined by segments.
7.1 Create the tolerance range
To create a new tolerance range, use the EDIT JOB > TOLERANCE RANGE menu. If the tolerance range
does not exist, confirmation is requested for the creation of a new one. Choosing YES, a simple tolerance
range formed by two points for each edge appears in the graph.
7.2 Modify the tolerance range
To modify the tolerance range use the EDIT JOB > TOLERANCE RANGE menu. When moving the points,
be careful not to switch the top edge with the bottom edge.
The modification of the tolerance range must be performed by moving the points that determine the two edges.
When the tolerance range is modified, only one point of one of the two edges is highlighted, this point is the
active one, i.e. it is the one that can be moved using the keys . It is possible to change the
active point with the "select previous point" and "select next point" commands. To activate the points of the
other border, press the command "select other edge". The force and position of the active point are displayed
below the graph.
You can add a point by dividing the segment following the active point in two parts. To do this, press the "add
new point" command.
It is possible to delete the active point with the “delete point” command.
When using the arrow keys, it is possible to change the speed by pressing the "change size of step" command.
