(M series)
Tool compensation values include tool geometry compensation values
and tool wear compensation values (Fig. 10.2 (a)).
The geometry compensation and wear compensation can be unified to the
tool compensation.

Tool compensation values can be entered into CNC memory from the
CRT/MDI panel or from a program.
A tool compensation value is selected from the CNC memory when the
corresponding code is specified after address H or D in a program.
The value is used for tool length compensation, cutter compensation, or
the tool offset.
Tool offset amount range which can be set is as follows:

The memory can hold 400 sets of tool compensation values.
Type of tool compensation is C.
Tool compensation memory C
Memory for geometry compensation and wear compensation is pre-
pared separately in tool compensation memory C. Geometry com-
pensation and wear compensation can thus be set separately. Separate
memories are prepared for cutter compensation (for D code) and for
tool length compensation (for H code).
