9 Tool Offsets
9.1 Tool data
The geometrical tool data for the tool are stored under tool offset number D:
Radius ±9999.999 mm
Length ±9999.999 mm
input resolution 1µm
T-number 8 decades
Tool type
In the standard control the tool offset block is divided into 10 columns (P0 to P9). The format
of the tool offset block is identified by the tool type (P1). The number of tool offset blocks
depends on the number of tool offset parameters per block and the size of the tool offset
memory.
The tool offset is called in up to 3 decades via D1 to D... It is cancelled with D0. The offset is
not executed until the corresponding axis is programmed.
The tool number, tool type, geometry, basic dimension and wear of all active tools are stored
in the TO area of the NC. The geometry and wear are updated, for example by measuring
cycles in the NC. The wear and basic dimension are totalled in the NC in accordance with the
machine data.
Breakdown of tool type P1
Type 0 Tool not defined
Type 1 . . . 9 Lathe tools, position of tool tip
Type 10 Tools with active length compensation only (e.g. drills)
Type 20 Tools with radius compensation and one length compensation (e.g. cutters)
Type 30 Tools with radius compensation and two length compensations
(e.g. angle cutter)
Type 40 Cutter for 5-axis tool length compensation (option)
Tool offsets can be entered both through the operator panel and the data input interface, but
no block numbers must be programmed (see punched tape formats).

It can be defined via machine data that tool type 0 act
like tool type 20. Radius and length compensation are
then assigned as for type 20. The display type 0
remains unchanged.
