Tool geometry variables (length, radius)
The tool geometry variables consist of several components (geometry, wear). The control
computes the components to a certain dimension (e.g. overall length 1, total radius). The
respective overall dimension becomes effective when the compensation memory is
activated.
How these values are calculated in the axes is determined by the tool type and the current
plane (
