5.2 Tool length compensation

5.2 Tool length compensation
The tool length compensation compensates for the differences in length between the tools
used.
The tool length is the distance between the toolholder reference point and the tool tip:
This length is measured and entered in the tool compensation memory of the control together
with definable wear values. From this data, the control calculates the traversing movements in
the infeed direction.
Note
The offset value for the tool length is dependent upon the spatial orientation of the tool.
