Abstract
A control device for controlling a machine tool which can be used to drive tools includes a memory for storing a movement limit value which is respectively assigned to the tools and is specific to the respective tool. A desired value generating unit generates desired values for controlling the movement of the tool. The desired values are limited by a limiting unit on the basis of the assigned movement limit value in such a manner that the movement limit value is not exceeded when moving the tool.
Claims8
A control device for controlling operation of a machine tool to drive a tool, said control device comprising:
- a memory storing a movement limit value which is specific to a tool;
- a desired value generating unit generating a desired value for controlling a movement of the tool;
- and
- a limiting unit determining a limited desired value by limiting the movement limit value, such that the movement limit value is not exceeded when the tool moves.
A machine tool, comprising a control device which includes a memory storing a movement limit value which is specific to a tool, a desired value generating unit generating a desired value for controlling a movement of the tool, and a limiting unit determining a limited desired value by limiting the movement limit value, such that the movement limit value is not exceeded when the tool moves.
A method for safely operating a machine tool which can be used to drive a tool, comprising the steps of:
- assigning a movement limit value which is specific to a tool;
- storing the movement limit value;
- generating a desired value for controlling a movement of the tool;
- generating a limited desired value by limiting the desired value as a function of the movement limit value;
- and
- limiting the tool-specific movement limit value with the limited desired value to prevent the movement limit value from being exceeded when the tool moves.
