LASER 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 کاملExperimental 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 کاملThe Effect of Power and Maximum Cutting Speed on the Material Removal Rate and Cutting Volume Efficiency in CO2 Laser Cutting of Polycarbonate Sheets
In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...
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 کاملThe Laser Cutting Optimization by Neural Networks
Aim of this contribution is to present the optimization of the laser cutting process by artificial neural networks. NeuroSolution for Excel 1.02 was used in order to interpret complicated dependencies between technological characteristics of laser cutting and output parameters. Multilayer feed forward neural networks are utilized for modelling and prediction of input parameters of laser cutting...
