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 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 کاملLaser Beam Hazard for flight personnel
Lasers can produce a beam of light of such intensity that permanent damage to human tissue, in particular the retina of the eye, can be caused instantaneously, even at distances of over 10 km. At lower intensities, laser beams can seriously affect visual performance without causing physical damage to the eyes; causing transient damage or causing sensation and loss of focus. Laser illumination o...
متن کاملOptimal beam forming for laser beam propagation through random media
Focusing optical beams on a target through random propagation media is very important in many applications such as free space optical communications and laser weapons. Random media effects such as beam spread and scintillation can degrade the optical system’s performance severely. Compensation schemes are needed in these applications to overcome these random media effects. In this research, we ...
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...
