“…Because the feed amount, f, was much smaller than the radius of the tool nose, R, for a clearer expression, the actual vortex-line track of the tool nose was simplified into three double-point scribe-line circular tracks. The relationships between the rotational speed, n, the feed rate, F, the feed amount, f, the maximum surface roughness, Rz, the cutting velocity of the tool nose, v, and the actual maximum cutting depth, apm, are shown in Equations ( 7)- (10):…”

“…The diamond micro-chiseling method can be used to process micro-cube arrays with complex shapes [9]; this procedure has stringent machine tool requirements and a complex tool-setting process. The machining efficiency of forming microstructures with a grinding wheel is high, but the abrasive particles fall off the wheels during grinding, thereby causing damage to the machined surfaces [10,11]. V-shaped diamond planing tools allow for the machining of MTPAs with slow cutting speeds, large cutting forces, large material plastic deformation, and the generation of burrs on the MTP edges [7,12].…”

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.
