Tool compensation values include tool geometry compensation values
and tool wear compensation (Fig. 15.5 (a)).
Tool compensation can be specified without differentiating compensation
for tool geometry from that for tool wear.

Tool compensation values can be entered into CNC memory from the
CRT/MDI panel (see section III–9.1) 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.
See subsec. II–15.1.2 for details.
Table 15.5.1 shows the valid input range of tool compensation values.
