M128 with 3-D tool compensation
If you carry out a 3-D tool compensation with active M128 and active
radius compensation G41/G42, the TNC will automatically position the
rotary axes for certain machine geometries (Peripheral milling,
see
“Peripheral Milling: 3-D radius compensation with workpiece
orientation,” page 146).
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.
To cancel M128, enter M129. 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.
