在超精密光栅飞切（UPRFC）中，在加工表面上发现3.42 MHz-6.36 MHz范围内的甚高频微波。这项研究进行了一系列的理论和实验研究，以发现这些微波的起源以及如何抑制它们。研究结果表明：（i）在UPRFC中，在切屑形成期间，在加工表面上的微波是由材料滑动引起的;（ii）由于切屑沿着其长度方向的不一致厚度，微波在每个进给长度中的表面出口处积累;以及（iii）切屑厚度和工具磨损改变微波的长度和分布。这项研究提供了一个深入了解微波形成的沿着与建议，如何抑制他们。
In ultra-precision raster fly cutting (UPRFC), very high frequency microwaves in the range of 3.42 MHz–6.36 MHz are found on the machined surface. This study conducted a series of theoretical and experimental investigations to discover the origin of these microwaves and how they might be suppressed. Research results show that: (i) microwaves on the machined surface are caused by the material sliding during the chip formation in UPRFC; (ii) owing to the inconsistent thickness of chips along their length direction, the microwaves accumulate at the surface-exit in each feed length; and (iii) chip thickness and tool wear change the length and distribution of the microwaves. This research provides a deep insight into the formation of microwaves along with suggestion on how to suppress them.
