Abstract
When forming a micromachined part by water jet guided laser machining at a machine component 20, a point for forming a micromachined part is machined while moving a laser head 7 side and machine component 20 side so as to obtain a desired shape of a micromachined part.
Claims8
A machining method for micromachining a part at a machine component by water jet guided laser machining,
- which method moves the laser head outputting a laser beam together with high-pressure water and the machine component for machining to obtain a hole of the micromachined part having a fan-shaped longitudinal cross-sectional shape or a circular shape when applying water jet guided laser machining to a machining point for forming the micromachined part of the machine component, and
- which method starts said water jet guided laser machining at a start point being more inner than the outermost circumference position of said hole, and after the start of said water jet guided laser machining, moves the laser head or the machine component back and forth in a predetermined direction at the inner more side than the outermost circumference position of the hole and then, machines the outer circumference side of the hole.
