“…Because the fly-cutting method is a discontinuous cutting method, it inevitably produces many micro-scraps with thicknesses of approximately 2 mm. Some of the microscraps that remain on the MTP surfaces are squeezed and scratched by the diamond tool; thus, they can easily produce scratches on the surfaces of the MTPAs, and can even cause the edge or tip of the diamond tool to break [15,16]. Therefore, it is necessary to continuously remove micro-scraps when using the fly-cutting method to process MTPAs.…”

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 this study. The results show that an MTPA produced by fly cutting on a vertical workpiece had a clearly 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.
