Workpiece cutting method using cutting beam has at least one cutting parameter modulated for improving quality of cut surface

摘要

The cutting method has a cutting beam displaced relative to the workpiece along a cutting line, with at least one cutting parameter affecting the surface structure at the cut surface modulated via a periodic frequency during the cutting process. The modulation frequency is of the order of the reciprocal spacing of ridges or grooves formed upon cutting without modulation multiplied by the cutting beam displacement rate.
