WinMax Lathe NC Programming
Main Spindle Stop (ISNC M5)
M5 turns the main spindle (S1) off. M5 executes at the end of the block after all motion
occurs. Execute after tool change or motion (system M codes).
Format
S1:M5
Live Tool CW (ISNC M33)
M33 turns the live tooling spindle (S2) on in the clockwise direction. M3 will execute after
Tool, Spindle, and E (Work Offset) codes execute, but before motion programmed in the
block occurs.
An S code specifying the spindle speed must be programmed before the spindle will turn
on. The advanced RPM Look Ahead feature that reduces part cycle time by ramping the
spindle up to speed before the feed move begins improves the cycle time because the
control does not dwell while the spindle ramps up to the programmed speed. When this
feature is active, it is possible to create a part program containing an M33 and spindle
speed command that does not turn on the spindle.
Execute after T and S codes, but before motion.
Format
S2:M33
Live Tool CCW (ISNC M34)
M34 is the same as M0 except it commands the live tooling spindle (S2) to rotate in the
counterclockwise direction. Execute after T and S codes, but before motion.
Format
S2:M34
