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 ...
متن کاملLaser Cutting Theory
A laser can be used for cutting by exposing material to the intense heat energy developed by its beam. If that heat input to the material is greater than that material's ability to reflect, conduct, or disperse the added energy, it will cause a sudden rise in temperature of the material at that point. If the temperature rise is substantial enough, the input heat is capable of initialising a hol...
متن کاملLASER CUTTING PARAMETERS The laser cutting parameters are dependent on the beam characteristics, the cutting rate
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 a...
متن کاملAssessing the Strength of Carbon Fibres
Data on the strength of carbon fibres, first examined by Crowder (1994), are re-analysed. The new analysis is Bayesian and is implemented using Markov chain Monte Carlo methods. The flexibility of this approach allows an extended form of Crowder’s model to be considered, and provides more reliable measures of precision for parameter estimates. The results obtained lead to an improved understand...
