Abstract
A spindle motor rotates a spindle to which a cutting tool is attached. A feed mechanism moves the cutting tool relative to a thin workpiece. A machining apparatus repeatedly performs a first process of causing the feed mechanism to feed the cutting tool relative to the thin workpiece in a height direction of a rising wall to perform a plunge process on the thin workpiece, and a second process of causing the feed mechanism to feed the cutting tool relative to the thin workpiece in a width direction or the height direction of the rising wall to perform a finishing process on the thin workpiece.
Claims5
A machining method for forming a rising wall by machining a workpiece, the machining method comprising:
- a first process of feeding a cutting tool relative to the workpiece in a height direction of the rising wall to perform a plunge process on the workpiece;
- and
- a second process of feeding the cutting tool relative to the workpiece in a width direction of the rising wall to perform a finishing process on the workpiece, wherein
- each time a cusp is generated after the first process, the second process is performed to remove the cusp, and the first process and the second process are repeatedly performed to form the rising wall having a ratio of a height to a wall thickness greater than or equal to 10.
