影响超精密车削表面粗糙度几种主要因素分析

摘要

论述了影响超精密车削表面粗糙度的几种主要因素，详细分析了刀具几何形状、最小切削厚度、不规则的金属变形、切削用量、振动等因素对加工表面粗糙度的影响，为超精密车削加工表面质量的控制提供了依据。%The paper discusses the main factors that effect the surface roughness in ultraprecision turning. A detail analysis is made on the influence of geometry of tools, minimum cutting thickness, non-uniform surface deformation, cutting parameters, vibration, etc. On machined surface roughness. It provides an effective evidence for control of surface quality in ultraprecision turning.
