Programming
10.6 Tool and tool offset
Tool length compensations become effective immediately when the tool is active; when no D
number was programmed with the values of D1.
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.

● Geometrical dimensions: Length, radius
● The tool type
● Cutting edge position
The following figures provide information on the required tool parameters for the respective
tool type.

Tool change:
These consist of several components (geometry, wear). The control systems computes
the components to a certain 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 determines which geometry data are required and how they will be
computed (wheel types).
For dressers, you must also enter the cutting edge position.
