Title:
切削工具製造方法
Document Type and Number:
Japanese Patent JP6980216
Kind Code:
B2
Abstract:
A controller performs a first process of scanning a cylindrical irradiation region including a focused spot of laser light emitted from a laser light emitter to machine a flank face side of a workpiece to manufacture a cutting tool having a plurality of cutting edges arranged in line. In the first process, the controller scans the cylindrical irradiation region along a scanning path that has periodicity and changes a machining depth to form the plurality of cutting edges. The controller further performs a second process of scanning the cylindrical irradiation region including the focused spot of the laser light emitted in a direction different from an irradiation direction of the laser light in the first process to machine a rake face side of the workpiece.
