Zero Width Glass Cutting with CO2 Laser
Laser cutting of glass in not a novel technique, excellent results have already been achieved by various research institutes. There are several patents concerned with controlled cutting of glass with zero width and other brittle materials in a straight line using CO2 laser beam. Laser beam glass cutting produces a high quality cut edge with minimal microcracking. This is achieved using a contro...
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 کاملThe effects of power rippling on CO2 laser cutting
A power rippling method was proposed in this study to improve the cut edge quality by disturbing the natural frequency of the periodic striations in high power CO2 laser cutting. A pilot study was also designed and set up to examine the power responsibility of the laser system, which is externally controlled by a modulated analogue signal from a signal generator. Several aspects were examined i...
متن کاملA Numerical Investigation into Cutting Front Mobility in Co2 Laser Cutting
-The technologically important case of reactive gas laser cutting is examined. A transient twodimensional (2D) model is developed specifically to investigate the effect of various CNC velocity profiles on the resulting cutting front temperature. Co-ordinated motion systems must ramp up and down to their target speeds, and therefore such accelerations must be considered. In doing so, the dynamic...
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 ...
