Starting a New NC Program
Procedures for entering the program name, the part setup information, the tool
descriptions, and the program parameters are described in Getting Started with WinMax
Lathe, Project Manager, on page 3 - 1 and Programming Basics, on page 4 - 1, in addition
to information about saving files.
The parameters, part setup (except work offsets), and tool setup (except tool offsets)
used for NC programs are not stored as part of the NC program. This information can be
loaded from a Conversational program before going into the NC mode.
Part and tool setup information is not automatically deleted or replaced when loading a
new NC program. If part and tool setup information appears on the setup screens after
loading in a new NC program, it is the setup information from the previously displayed
part program.
When there is no NC program loaded in memory, the system automatically assigns the
filename NONAME#, where the # represents a sequential number from 0 to 99. The file
extension is set in User Preferences. Refer to Getting Started with WinMax Lathe, Project
Manager, on page 3 - 1.
These steps for creating an NC part program help determine the most efficient tool
movement and basic program structure to save time during programming:
1. Determine the tool path on the print and label the points where the path
direction changes.
2. Make a chart showing the coordinates of each point identified in the previous
step.
3. Identify the turret movements that will be necessary during cutting.
NC Programming Rules
Here are some basic rules to follow when creating NC part programs:
• The axis letter always precedes the numeric information.
• In most cases an integer works the same as a decimal or real number. In the
following cases an integer is scaled by the appropriate scaling factor to
maintain compatibility with existing NC programs:
Feedrate: F (BNC only)
Rotation: R (ISNC only)
Dwell: P, X (Both BNC and ISNC)
Scaling: P (ISNC only)
If an integer is below the acceptable range after scaling, a “Below
Minimum Value” error message occurs.
