(1)Tool compensation memory C
Memory for geometry compensation and wear compensation is sepa-
rate in tool compensation memory C. Geometry compensation and
wear compensation can thus be set separately. Separate memories are
prepared for cutter compensation (for D code) and for tool length com-
pensation (for H code).
The above description is summarized as follows:
Tool compensation

Compensation amount
Geometry compensation value for H code
Geometry compensation value for D code
C
Wear compensation value for H code
Wear compensation value for D code
Tool compensation values include tool geometry compensation values
and tool wear compensation values (Fig. 10.2.1 (b)).
Tool compensation can be specified without differentiating compensation
for tool geometry from that for tool wear (Fig. 10.2.1 (c)).

Tool compensation values can be entered into CNC memory from the
MDI unit or from a program.
A tool compensation value is selected from the CNC memory when the
corresponding code is specified after address T in a program.
The value is used for tool offset or tool nose radius compensation.
Tool offset amount range which can be set is as follows:
