WinMax Lathe NC Programming 704-0115-307 Documentation Conventions — xv
DOCUMENTATION CONVENTIONS
This documentation uses several conventions to explain the safety features and
emphasize key concepts. These conventions are described in this section.
Additional information is available on the machine’s Documentation CD.
Sample Screens
Sample screens in this documentation were taken from a WinMax single-screen control.
All screens are subject to change. The screens on your system may vary slightly. The
sample screen here illustrates softkeys and includes a software version.
Softkeys
Softkeys are located on the side of the screen. You can set the softkeys to appear on
either the right or left side of the screen. Refer to the Getting Started with WinMax for
information about making this selection. Softkeys may change upon field entries or other
softkey selection. References to softkeys in the documentation appear with the softkey’s
corresponding F-key. For example, the Part Setup softkey from the Input screen above is
referenced as the PART SETUP F1 softkey.
Screen Areas
The screens are divided into the following areas, in addition to the row of softkeys:
Data Entry
Prompts
Status Bar
Error/Status Area
Softkeys
F1 to F8
Data Entry Area

xvi - Documentation Conventions 704-0115-307 WinMax Lathe NC Programming
The data entry area is located on the opposite side of the screen from the softkeys.
Available softkeys may change even when the text and data entry area does not.
Fields in the data entry area display or receive information. Refer to Using the
Touchscreen for information on entering information in fields.
Prompts and Error/Status Area
The bottom portion of the screen is reserved for prompts, program status and error
messages.
Prompts provide help on data entry selections based on the field with the blinking cursor.
Errors and status messages occur anytime the status or error occurs. They are not based
on the field with the blinking cursor. These messages provide machine information to the
operator.
Error messages may also stop and/or prevent machine operation until the cause of the
error is corrected.
Status Bar
The status bar contains
• The name of the open, selected program.
• A calculator icon—select the icon to display a working, on-screen calculator.
• Units of measure (Inch or Millimeters)—select the units of measure in the
status bar to toggle between Inch and Metric.
• Programming mode (R for Radius; D for Diameter)—select the programming
mode in the status bar to toggle between Radius and Diameter.
• A yellow icon—indicates the feed hold is on when visible.
• A red icon—indicates the Emergency Stop button has been pressed when
visible.
• A keyboard icon—select the icon to display a working on-screen keyboard.
• The current time.
When viewed on a single-screen console, all icons appear in the same status bar; when
viewed on a dual-screen console, the program name and calculator icon appear on the
left screen status bar, and the unit of measure, keyboard icon and time appear on the
right screen status bar.
Console Buttons and Keys
References to console buttons and keys appear in bold text throughout the
documentation. For example, the Start Cycle button appears as the Start Cycle button
and the Manual key appears as the Manual console key in text.
Refer to the Getting Started with WinMax manual for information about console buttons
and keys, in addition to other information about using softkeys and the pop-up text entry

window.
Using the Touchscreen
The console has a touchscreen for entering programming data. To make a selection, tap
the screen on a softkey, field, or drop-down list using the stylus attached to the side of the
console or another suitable pointing device.

PROGRAMMING AND OPERATION
INFORMATION
Hurco provides documentation for using WinMax software on a control or desktop in two
formats: on-screen Help and PDF. The information contained in both formats is identical.
On-screen Help contains information about the current screen. If Help is not available for
a screen, a Welcome screen appears with access to the Table of Contents, Index, or
Search functions.
• To view the on-screen Help directly on a Hurco control, select the Help
console key.
• To view the on-screen Help on the desktop software, select the Help icon in
the menu bar.
PDF files are available on the hard drive. These files can be copied from the hard drive to
a USB memory device and transferred to a PC for viewing and printing.
Using the On-screen Help
On-screen Help provides information about using WinMax. The Help is context-sensitive
to the screen level. Press the console Help button to display the Help topic for the current
screen. The following list describes Help functions:
• Buttons in the upper left-hand corner of the Help screen are used to move
through Help topics and print screens.
•UsetheHide button to hide the navigation pane.
•UsetheBack button to return to the previous Help screen.
•UsethePrint button to print the current displayed Help topic, if a printer
is attached and configured. See Printing the Programming Manuals, on
page - xix for more information about printing.
• Use the arrow buttons to move between pages within a Help topic and to
move through topics.
•UsetheContents tab for a list of information sorted by subject:
1. Select the “+” to expand the topic and view sub-topics.

Printing the Programming Manuals
The WinMax On-screen Help is also provided in PDF format for easy printing. The
information contained in the PDF files is identical to the on-screen Help. The PDF files
may be copied to a floppy disk or USB memory device to be transferred to a PC for
printing. Here are the steps to access the PDF files:
1. From the Input screen, select the PROJECT MANAGER F8 softkey.
2. Select the FILE MANAGER F7 softkey.
3. In the left-hand pane, navigate through the folders:
• For WinMax Lathe on a machine, the path is D:\Hurco\Hurco Lathe\hlp.
• For WinMax Desktop on a PC, the path is C:\Program Files\Hurco\Hurco
Lathe\hlp.
The PDF files will appear in the right-hand pane.
4. Highlight the PDF file(s) in the right-hand pane, and select the COPY F2
softkey.
5. Ensure that your media is loaded (either a floppy disk in the disk drive or a
USB memory device in the USB port), and navigate to the proper location in
the left-hand pane of the DISK OPERATIONS screen (either the floppy drive A:
or the USB port E:). Highlight the desired location.
6. Place the cursor in the right-hand pane and select the PASTE F3 softkey to
paste the PDF file(s) to the desired location.
You may now remove your media and load the PDF file(s) onto a PC for printing.
The SHOW ALL FILE TYPES field in User Interface Settings must be
set to YES (default is NO) in order to see the PDF files in the
directory. Access the SHOW ALL FILE TYPES field in Auxiliary Mode,
Utilities/ User Preferences/ User Interface Settings.
