Rotatably driven tool controlling method, involves determining radius at tool, where determined radius is compared with reference value to be corrected, in order to obtain radius comparison value

摘要

The method involves determining radius at a tool (4), where the determined radius is compared with a reference value to be corrected, in order to obtain radius comparison value. A new reference value is determined under utilization of the determined radius, when the radius comparison value violates a predetermined threshold. The reference value is substituted with the new reference value. An independent claim is also included for a program product with program code parts for the execution of the steps of a method for controlling a rotatably driven tool.
