Shaping Ceramics with a Continuous Wave Carbon Dioxide Laser
The application of the continuous wave carbon dioxide laser to processes such as straight-line cutting and hole drilling is well established.1 Recently the CW-CO2 laser has been used to shape ceramics in lathing and milling operations. In this report we present results on such shaping of Si2N4, SiAlON and SiC workpieces. A straightforward analysis is presented, which predicts the feed and power corresponding to a specific surface roughness grade and effective material removal rate.
