Abstract
A machine tool setup changing method includes mounting a master workpiece onto a tool spindle axis, deforming a gripping part by gripping, with the gripping part of a jig, a mock clamped portion of the master workpiece mounted on the tool spindle axis, and removing the master workpiece from the tool spindle axis and mounting a tool supported on a tool support device onto the tool spindle axis, wherein the workpiece gripped at the clamped portion by the gripping part, which was deformed in accordance with the mock clamped portion, can be machined with the tool.

A setup changing method for a machine tool including a tool spindle, a storage magazine which stores a tool which is exchangeably attachable to the tool spindle, and a machining jig having a gripping part which deforms in accordance with a shape of a clamped body of a master workpiece, the setup changing method comprising:
- mounting, onto the tool spindle, the master workpiece, wherein the clamped body of the master workpiece has the same shape as the shape of a clamped body of a workpiece to be machined;
- deforming the gripping part by gripping, with a plurality of straight displaceable pins of the gripping part, the clamped body of the master workpiece while the master workpiece is mounted on the tool spindle;
- removing the master workpiece from the tool spindle and storing the now removed master workpiece in the storage magazine;
- and
- mounting the tool stored in the storage magazine onto the tool spindle, wherein
- the workpiece to be machined, the clamped body of which is gripped by the gripping part that was deformed in accordance with the clamped body of the master workpiece, is machined with the tool.
A machining system, comprising:
- a machine tool including a tool spindle, a storage magazine which stores a tool which is exchangeably attachable to the tool spindle, and a machining jig having a gripping part which deforms in accordance with a shape of a clamped body of a master workpiece;
- and
- a controller that controls the machine tool, wherein
- the controller is configured to cause:
- the master workpiece, which is held in the storage magazine, to be mounted onto the tool spindle, wherein the clamped body of the master workpiece has the same shape as the clamped body of a workpiece to be machined;
- the gripping part to be deformed by gripping, with a plurality of straight displaceable pins of the gripping part, the clamped body of the master workpiece while the master workpiece is mounted on the tool spindle;
- the master workpiece to be removed from the tool spindle and to be stored in said storage magazine, and
- the tool supported in the storage magazine to be mounted onto the tool spindle, and wherein
- the workpiece to be machined, the clamped body of which is gripped by the gripping part that was deformed in accordance with the clamped body of the master workpiece, is machined with the tool.
