1.1 Basics
General information
Measuring cycles are general subroutines designed to solve specific measurement tasks.
They can be adapted to specific problems via parameter settings.
When taking general measurements, a distinction is made between
● tool measurements and
● workpiece measurements.
Workpiece measurements

<
;
:
In workpiece measurement, a measuring probe is moved up to the clamped workpiece in the
same way as a tool and the measured values are acquired. The flexibility of measuring
cycles makes it possible to perform nearly all measurements required on a milling or turning
machine.
An automatic tool offset or ZO correction can be applied to the workpiece measurement
result.

In tool measurement, the selected tool is moved up to the probe and the measured values
are acquired. The probe is either in a fixed in position or is swung into the working area with
a mechanism. The tool geometry measured is entered in the appropriate tool offset data set.

Programming Manual, 03/2009 Edition, 6FC5398-4BP10-2BA0 15
1.2 General prerequisites
Certain preconditions must be met before measuring cycles can be used.
These are detailed in Part 2 Description of Functions (Chapter 8 ff.).
The following checklist is useful for checking which preconditions have been met:
Machine
● All machine axes are designed in accordance with DIN 66217.
● Machine data have been adapted.
Existence of measuring cycles, data blocks
References:
Commissioning Manual SINUMERIK 840D sl base software and HMI sl
Starting position
● The reference points have been approached.
● The starting position can be reached by linear interpolation without collision.
Display functions of the measuring cycles
A HMI/PCU or HMI/TCU is required for showing the measuring result displays and for
measuring cycle support.
Please observe the following when programming:
● Tool radius compensation is deselected before it is called (G40).
● All parameters for the cycle call have been defined beforehand.
● The cycle is called no later than at the 5th program level.
● The system of units allows measuring in the programmed unit system that deviates from
the basic system with switchable technology data.
– For metric dimension system with active G70, G700.
– For inch-based dimension system with active G71, G710.

1.3 Behavior on block search, dry run, program testing, simulation
Measuring cycles
16 Programming Manual, 03/2009 Edition, 6FC5398-4BP10-2BA0
1.3 Behavior on block search, dry run, program testing, simulation
Function
The measuring cycles are skipped during execution if one of the following execution modes
is active:
•"Trial run" ($P_DRYRUN=1)
•"Program test" ($P_ISTEST=1)
•"Block search" ($P_SEARCH=1), only if $A_PROTO=0.
Simulation
● On HMI Advanced ($P_SIM=1)
The measuring cycle programs are executed when "Simulation" is selected on the HMI.
● On Jobshop products ($P_SEARCH=1 and $A_PROTO=1)
The measurements are simulated. No selected tool or zero offset is applied. Active functions
such as "measuring result display", "travel with collision monitoring", "measuring cycle
logging" are not executed.
Suppression of simulation execution
Execution of the measuring cycles in simulation can be suppressed in simulation by resetting
the variable _MC_SIMSIM=0 in data block GUD6. The measuring cycles are then skipped.
Specifying differences for simulation
The variable _MC_SIMDIFF of data type REAL permits specification of simulated
measurement deviations at measuring points. The value is a dimension in the basic system
of the control.
Excessive values of _MC_SIMDIFF with corresponding value assignment of the defining
parameters cause cycle alarms to be output.
Note
It is not ensured that the correction value contains the correct sign of _MC_SIMDIFF. This
depends on the measurement or calibration task and the direction of measurement. The sign
is influenced in such a way that the overall result makes sense (e.g. "Measure hole").
Changing the sign always causes the sign of the result to change.

1.4 Reference points on the machine and workpiece

1.4 Reference points on the machine and workpiece
General information
Depending on the measuring task, measured values may be required in the machine
coordinate system or in the workpiece coordinate system.
e.g.: It may be easier to ascertain the tool length in the machine coordinate system.
Workpiece dimensions are measured in the workpiece coordinate system.
Where:
● M = Machine zero
● W = Workpiece zero
● F = Tool reference point

The position of tool reference point F in the machine coordinate system is displayed with
machine zero M as the machine actual value.
The position of the tool tip (active tool) in the workpiece coordinate system is displayed with
workpiece zero W as the workpiece actual value. If a workpiece probe is active, the position
usually refers to the center point of the probe ball.
The zero offset (ZO) characterizes the position of the workpiece on the machine.
The ZO is the position of workpiece zero W in the machine coordinate system.
In addition to the pure offset, a ZO might also include rotation, mirroring, and a dimension
factor. Together these are termed a frame.

Measuring cycles

SINUMERIK controls use numerous frames: various basic frames, system frames, settable
frames (e.g. G54), programmable frames: They interact in a frame chain to produce the
overall frame and the workpiece coordinate system.
Measuring cycles do not support any frames with an active scale factor. Rotation or mirroring
is not supported in some cycles and measuring variants.
The machine and workpiece coordinate system can be set and programmed separately in
the "inch" or "metric" measuring system.
Note
Transformation
If kinematic transformation is active, the control makes a distinction between the basic
coordinate system and machine coordinate system.
If kinematic transformation is deactivated, this distinction is made.
All descriptions provided below assume that kinematic transformation is deactivated and
therefore refer to the machine coordinate system.

1.5 Definition of the planes, tool types
The G17, G18 or G19 tool radius correction planes can be selected.
Depending on the tool type, the tool lengths are assigned to the axes as follows:
● Milling cutter, workpiece probe for milling: 1xy or workpiece probe for milling: 710
● Drill: 2xy
● Turning tool, workpiece probe for turning: 5xy
