Programming principles
1.6 Tool and tool offset
The compensation is retracted with the first programmed traversing of the associated length
compensation axis.
A tool radius compensation must also be activated by G41/G42.
Programming example
Tool change:
N10 T1
N20 G0 X100
N30 Z100
N40 T4 D2
N50 X50 Z50
N60 G0 Z62
N70 D1
N80 M30
Contents of a compensation memory
● Geometrical dimensions: Length, radius.
● Tool type
● Cutting edge position
The following figures provide information on the required tool parameters for the respective
tool type.

They consist of several components (geometry, wear). The control takes into account the
components to obtain a resulting dimension (e.g. overall length 1, total radius). The
respective overall dimension becomes active when the offset memory is activated.
The way in which these values are computed in the axes is determined by the tool type
and the current plane G17, G18, G19.
The tool type (drill or turning tool) determines which geometry data are required and how
they will be calculated.
For the "turning tool" tool type, you must also enter the cutting edge position.
