Y. Cautions and remarks tool compen-
sation C
A . Maximum programmable dimensions (Refer to
Table 2. 14) is not changed even in tool
radius compensation C.
B. Programmed shapes that produce input
errors
Input error “ 045” occurs with the follow-
ing programmed shapes.

Tool radius compensation C is applied to
the movement path offset by tool length
offset and tool position offset.

in principle, avoid applying compensation
C to the path using tool position offset
for compensation of tool radius.
When programming G41, G42 and GOO
or GO1 and an F code should be program-
med in the same block or in a preceding
block.
