3.1 Fundamentals
With the shown positioning blocks with vectors, 3-
D tool compensation is possible with compensation
values DL, DR and DR2 from the TOOL CALL block.
The methods of function of the compensation values
depend on the type of tool.
The control detects the various tool types with the
columns L, R and R2 of the tool table:
R2
→ end mill
R2
DR
→ radius cutter or ball cutter
0 < R2
+ DR
→ toroid cutter or toroidal cutter
Without the TCPM function or miscellaneous function
M128, orientation of the tool coordinate system and
input coordinate system is identical.
