Japanese Patent JP2014121746
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cutting work method in a machine tool which can improve machining accuracy in comparison with conventional methods.SOLUTION: Both ends of a turbine blade W are processed while being held by clamp mechanisms 4. In the middle of the processing, a servo motor 2 of one work headstock 1b is turned off, and one end side of the turbine blade W is made rotatable. The one end side of the turbine blade W is automatically rotated by distortion due to processing heat, whereby the distortion can be eliminated. Consequently, a turbine blade W with high machining accuracy can be manufactured.
