EFFECTS OF CUTTING PARAMETERS ON KERF SIZE VARIATIONS OF THICK SHEET METAL

Mechanical Engineering

Laser cutting of thick sheets, in general, leads to poor end result quality thanks to excessive thermal erosion from the kerf sites. within the gift study, optical device melting of thick steel sheets is taken into account and result of cutting parameters on the share of kerf breadth variation is examined. The cutting parameters thought-about embrace optical device output power, cutting speed, and O helping pressure. A factorial analysis is applied to spot the main effects and interactions of the parameters. Thermal potency of cutting and liquid layer thickness is developed. Optical research and scanning microscopy (SEM) square measure applied to look at the cutting defects and also the kerf size variation. it's found that optical device output power and pressure have important result on the share of kerf breadth variation.
