Abstract
A computer program product, a control unit, a machine tool and method for operating a machine tool includes providing a control command set for a tool, providing an actual contour of the workpiece, determining a first material entrance point of the tool into the workpiece and generating a first positioning command for an approach to the first material entrance point, wherein the first positioning command specifies a track path which differs from a track path specified by the control command set, where as an alternative, or additionally, a rapid movement of the tool and or clamping of the workpiece is specified by the first positioning command.
Claims16
A method for operating a machine tool, comprising:
- a) providing a control command set via which a desired machining of a workpiece is defined;
- b) providing an actual contour of the workpiece;
- c) calculating a first material entrance point of a tool into the workpiece based on the actual contour of the workpiece;
- and
- d) generating a first positioning command for an approach to the first material entrance point;
- wherein the first positioning command specifies a track path which differs from a track path specified by the control command set;
- wherein said calculating is performed via a collision avoidance unit of the machine tool;
- wherein the track path has an abbreviated traverse section and the actual contour of the workpiece is produced by detection of the workpiece;
- wherein the first positioning command generated during said generating is dominant in comparison to a specification of the control command set;
- and
- wherein the method is performed in real-time.
A control unit for a machine tool, the control unit comprising:
- a computing unit;
- and
- a storage unit;
- wherein the control unit is configured to:
- a) provide a control command set via which a desired machining of a workpiece is defined;
- b) provide an actual contour of the workpiece;
- c) calculate a first material entrance point of a tool into the workpiece based on the actual contour of the workpiece;
- and
- d) generate a first positioning command for an approach to the first material entrance point;
- wherein the first positioning command specifies a track path which differs from a track path specified by the control command set;
- wherein said calculation is performed via a collision avoidance unit of the machine tool;
- wherein the track path has an abbreviated traverse section and the actual contour of the workpiece is produced by detection of the workpiece;
- wherein the first positioning command generated during said generation is dominant in comparison to a specification of the control command set;
- and
- wherein the method is performed in real-time.
