In precision machining, why use a very low or high-speed cutting of low surface roughness?
Why use lubrication cutting fluid, a large rake angle, feed rate and tool surface roughness of the
primary angle of small low? Why work-piece material hardness, brittleness of the material, the
low roughness during cutting? How to ensure processing quality, it is worth considering. This
article discusses the process of plastic materials in cutting a common physical and mechanical
effects, the growth conditions BUE, disappeared, prevention measures, and surface roughness on
the impact of finishing. This paper describes the formation of BUE, analyze it, find the best
programs and control methods.
