M128 with 3-D tool compensation
If you carry out a 3-D tool compensation with active M128 and active
radius compensation RL/RR, the TNC will automatically position the
rotary axes for certain machine geometrical configurations (peripheral
milling, see “Three-Dimensional Tool Compensation (Software
Option 2),” page 218).
Effect
M128 becomes effective at the start of block, M129 at the end of block.
M128 is also effective in the manual operating modes and remains
active even after a change of mode. The feed rate for the
compensation movement will be effective until you program a new
feed rate or until you reset M128 with M129.
Enter M129 to cancel M128. The TNC also resets M128 if you select a
new program in a program run operating mode.
Example NC blocks
Feed rate of 1000 mm/min for compensation movements.
