Fly-Cutting Processing of Micro-Triangular Pyramid Arrays and Synchronous Micro-Scrap Removal

Blog Article

Many micro-scraps are generated when a micro-triangular pyramid array (MTPA) is machined by the fly-cutting method.Micro-scraps are generally not removed quickly enough; therefore, these residual micro-scraps participate in the cutting process again, scratching the workpiece surface and accelerating diamond tool wear.To remove micro-scraps rapidly, a fly-cutting method to produce MTPAs on vertically oriented working surfaces was developed during taylor te400 this study.The results show that an MTPA produced by fly cutting on a vertical workpiece had a clearly wac 4011 outlined structure, high dimensional accuracy, and a low surface roughness.There was no micro-scrap residue on the workpiece surface and the diamond tool wear was small.

The cutting inlet edges had no burrs, and the cutting outlet edges had only a small number of burrs.This method of fly cutting MTPAs on vertically oriented working surfaces provides a foundation for the development of high-precision micro-triangular pyramid optical elements.
