Investigation into Roughness of Surface Polished by Abrasive Waterjet with Taguchi Method and Dimensional Analysis

摘要

Abrasive water jet was utilized to polish the 40CrMnMo7 mold steel and BK7 glass in this experiment designed by Taguchi method. The influence of polishing parameters on the polishing quality, their significance order, and the optimum polishing parameters were analyzed and reported. With the experimental data, the mathematic molds of surface roughness of polished workpieces were created by dimensional analysis, and then they were validated by the test experiment.
