WinMax Lathe NC Programming
Overview
G Codes initiate axis motion, plane changes, and feedrate changes. This information is
often needed when using an off-line CAM or CAD/CAM system to create NC part
programs.
Any unrecognized code will stop execution and display an error message. More than one
G code can be specified in the same block. If more than one is from the same group, the
last G code entered is active.
G Code Groups
The G codes are grouped by function. These groups are listed in the following table:
Table 2–1. G Code Groups
Some G Codes are on by default at the start of a program until
another G Code cancels it. Defaults are identified below.
Group Function
00 One-Shot
01 Interpolation
03 Dimension
05 Feed
06 Measurement
07 Cutter Compensation
09 Canned Cycles
10 Return from Canned Cycles
14 Coordinate System Selection
20 Speed
21 Programming Mode
Specifying a Group 01 (Interpolation) G code in a canned cycle
automatically enters the G80 condition (Cancel Drill Cycle).
Conversely, a group 01 G code is not affected by the canned cycle G
codes.
