Abstract:
The basic principle of laser drilling is introduced in this paper. The influence of laser energy, defocusing amount and trajectory during the ceramic blind hole processing on hole shape and surface quality was analyzed and verified in experiments. A general law is given. The rational process parameters were determined according to the test results. The rotation cutting was adopted to make the blind hole on Cf/SiC, whose diameter is 1 mm, depth is 1.1 mm and taper is less than 15°.
