Standard NC Programming Codes

 NC Programming Code


G00                       Rapid traverse
G01                       Linear interpolation
G02/G03               Circular interpolation
G04                       Dwell
G07                       Tangential circle interpolation
G08/G09               Path control mode (ramp at block transitions) and "Adaptive Look ahead" function
G10/G11               Block per-processing control
G12/G13               Circular interpolation with radius input
G17-G20               Plane selection
G33                       Thread cutting/rigid tapping
G36/G37               Programmable feed rate limitation
G38/G39               Mirror image
G40-G44               Tool radius compensation
G50                       Scaling
G51/G52               Part rotation
G53-G59               Zero offsets
G63/G66               Programmable feed rate/spindle speed override
G70/G71               Inch/metric dimension
G72/G73               Interpolation with in position stop
G74                       Home position
G80-G89               Canned cycles
G90/G91               Absolute/incremental programming
G92                       Position register preset
G94/G95               Feed rate
G160-G164           ART learning function
G186                     Programmable tolerance band

M00                       Program stop
M01                       Optional stop
M02/M30               End of program
M03/M04/M05       Spindle control (cw/ccw/stop)
M06                       Tool change (M-code depends on PLC)
M19                       Spindle orientation
M40-M46               Spindle gear transmission steps

All of the machine-specific functions have the M-code value configured in the PLC application.  Some of the M-codes, like M06 for a tool change and M07-M09 for coolant control, have typical assignments in many controls.  However this control does not require specific assignments.  Therefore, a machine function like the tool change does not have to be M06. The spindle control M-codes (3-5, 19, 40-46) also have configurable assignments.
