Title: Laser-assisted machining method
Inventor: GU YOU-BIN
IPC: B23K37/02
Filed: 2002-11-28
Abstract: Disclosed is a laser assisted machining method, wherein a laser pulse beam is employed to instantaneously soften a minute area of a workpiece at a small distance from and in front of a cutting tool, in order to weaken the strength of the portion behind the cut portion and reduce the resistance against machining so that when the tool is fed forward, the cut portion is caused to drive the softened portion and thus the cut portion and the softened portion can be quickly removed together. The same mechanism is repeated in the next irradiation of the laser beam. As such, the machining process is efficient and precise and removal rate and surface precision can be substantially enhanced, and the service life of the tool extended to significantly reduce the manufacturing costs.
