Control device for controlling a machine tool by which tools can be driven

摘要

The device (18) has a memory (3) for storing a movement limit value e.g. acceleration movement limit value, which is specific to a tool i.e. milling cutter (12a-12c). A desired value generating unit (1) generates a desired value e.g. desired speed value, for controlling a movement of the tool. A limiting unit (2) determines a limited desired value by limiting the movement limit value such that the movement limit value is not exceeded when the tool moves. A desired value determination unit (7) determines a change in the desired value from the limited desired value and desired values. An independent claim is also included for a method for safely operating a machine tool.
