Experimental Study of the Effect of Laser-Cutting Process Parameters on Heat Distribution and Cutting Edge Quality of Steel Sheets

This study aimed to evaluate Laser-cutting process of Mild Steel St37 sheets with two different thicknesses. In order to evaluate the quality of cutting edge and the depth of the area affected by the heat, several tests were conducted to determine the effect of parameters such as Laser power, Laser beam movement speed and pressure of axillary gas on the quality of cutting edge and the depth of ...

Influence of Cutting Speed on the Quality of Blanked Parts

The present paper covers and describes the influences of speed cutting on the part edge quality of blanked parts. Experiment shave been conducted using different material, punch die clearances and different cutting speeds. In order to determine the reachable cutting speeds and calculate the energy required for blanking, velocity stroke cures were obtained. The quality of the part edges shows th...

Influence of Laser Cutting Parameters on CFRP Part Quality

Material processing of Carbon Fibre Reinforced Plastics (CFRP) parts by means of shape-cutting or jet-cutting technologies is state of the art today. These processes still perform in some applications with lack of part quality such as delamination and low productivity. Therefore, laser cutting processes have a great potential in material processing of CFRP. Laser process parameters have to be a...

Comparison of Cutting Ceramics with Hard Metal Cutting Tools

Cutting ceramic tools are used especially at high cutting speeds in the machining process. The highly brittle type of structure and the tendency for cleavage (crack formation) are the infavorable properties of these materials, which keep their hardness at high temperatures. The hard metals are produced by sintering of the carbides such as whisker WC, TiC and TaC with the presence of Co as a bin...
