Modern machining processes usually require a machine that is capable of
selecting different tools. Typically tools are mounted in a turret and
assigned tool numbers as illustrated in Figure 10.6.

These data are set in the offset table corresponding to different offset
numbers:
tool length offset data
tool tip radius data
tool wear compensation data
tool orientation data
See chapter 3.
The selection of a tool number and an offset number for that tool is done
by programming a T-word.
Important: When you activate the MISCELLANEOUS FUNCTION
LOCK feature, the control displays M-, B-, S-, and T-words in the part
program and activates the corresponding Tool Wear Offset, with the
exception of M00, M01, M02, M30, M98, and M99. This feature can be
activated through the front panel screen as described in chapter 2.
The format for a T-word is determined in AMP by the system installer. Six
format selections are available as shown in Table 10.G.
