Abstract
In order to realize the laser precision machining of ceramics, the influence of some basic machining parameters (power, scanning speed, scan path spacing, and incidence angle) on the machining effect was studied. The experimental results show that the selection of reasonable processing parameters can obtain better processing quality and processing efficiency. The material removal rate firstly increases, and then decreases with the increment of the incident angle, which indicates that the incident angle has a great influence on the utilization of laser energy. In addition, the machined surface roughness is better after machining at high scanning speed and low power.
