چکیده
The laser cutting parameters are dependent on the beam characteristics, the cutting rate required, the composition and thickness of the material to be cut, and the desired cut edge quality. The laser cutting process and cut quality depend upon the proper selection of laser and workpiece parameters. Deficiencies in cutting quality may be related to the slow process drifts and disturbances that are caused by velocity fluctuations, variation in power and spatial intensity distribution as well as optical integrity perturbations. The effects of the beam parameters, process parameters and material parameters are described in the following sections.

متن کاملMachinability evaluation of Titanium alloy in Laser Assisted Turning
The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...
