Tool compensation values can be entered into CNC memory from the
MDI panel 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–14.1.2 for details.
Table 14.4.1 shows the valid input range of tool compensation values.
