The laser beam machining was carried out for leather with different levels of process parameters like Power (P), Transverse Speed (Sp), Standoff Distance (SOD) and Gas Pressure (G.Pr) and its effect on various response parameters such as MRR, Conicity, Overcut and Circularity are studied. ...
However, increasing both parameters is required until an optimum value for higher material removal rates are achieved. Cicala et al. [9] used an Nd:YAG pulsed laser for the machining of aluminum alloy, stainless steel, and titanium materials. They investigated the influence of the intensity, ...
The pursuit of any machining process is established by determining the equitable aggregate of input parameters. This paper deals with optimization of cut quality during pulsed CO2 laser cutting of mild steel. In the present paper, various input process variables such as laser power, cutting speed ...
A laser beam machining process and apparatus, applicable to laser beam perforation and cutting, in which a laser beam is directed onto a wall (4) of a component (6) to be machined from one side of the said wall and emerges on the other side thereof following the machining operation. ...
