英语翻译
To meet the demand for production and precision,researchers and equipment builders are looking outside the bounds of conventional milling,drilling,turning,and grinding.New cutting and machining processes continue to emerge along with methods for modifying the conventional techniques.
Laser-assisted machining.Laser-assisted machining is a process that has long been researched and now ready to come out the lab.In this operation,a laser beam is projected onto the part through fiber optics or some other optical-beam delivery unit,just ahead of the tool（as shown in Fig.34.1）.During a cut,laser power is varied to match the profile being cut.CO2 laser are usually used with power levels from 200 to 500 W.The laser-induced heat softens the workpiece and make it easier to cut.
