Abstract

Laser assisted machining (LAM) is used in machining difficult- To-machine materials such as hard alloys and ceramics. LAM uses a laser beam with high power density to heat the material within a very limited area, and then remove the heated area using a conventional cutting tool when the temperature of this heated area reaches a desirable range. In this paper, a laser assisted ultra-precision machining (LAUPM) system was developed and assembled into the Optoform 30 ultra-precision turning machine. Basic cutting experiment has been done to demonstrate the feasibility of using this system. The experimental result shows that a high accuracy of tool laser alignment could be achieved using a novel video microscope assisted adjusting method. The laser spot diameter and the cutting zone can be controlled in less than 100μm.
