want between absolute and incremental data input.
Within a block, you can also change the type of input for

Right-hand or left-hand threads are programmed by
specifying the direction of spindle rotation M3/M4. Spindle
rotation and speed must be programmed in the block

For programming taper threads, enter the X and Z
coordinates with G33. Multi-turn threads can be
programmed using the offset starting points (SF=& ).

Tool call
N10 T17 D8
T Call tool number
D Call tool offset, activate tool length
compensation
In order that the tool offsets are correctly taken into account
in the axes, before the tool is called, the machining plane
must be selected.
Tool offset values can be exchanged in the course of the
NC run. The machining plane does not have to be re-
programmed.
If no D number is to be input when the tool is called, a D
number can be specified via machine data.

In the NC block with G40/G41/G42, there must be at least
one axis programmed with the selected working plane (G17
to G19).
The offset must be selected or canceled in a program block
using G0 or G1. The compensation acts only in the
programmed working plane (G17 to G19).
