Abstract

The improvement of surface shape accuracy and surface quality is an important aspect of ultra-precision grinding. In this paper, experiments were carried out by using a four-axis ultra-precision grinder to analyze the influence mechanism of grating machining and polar axis machining on surface shape accuracy and surface quality, and to clarify the advantages and disadvantages of the two machining processes. In the process of polar axis machining, the influence of polishing on the surface shape accuracy is analyzed, and the influence of different feed modes and x direction offset on the surface shape accuracy is clarified. By establishing the influence model of the error source on the surface shape accuracy, the error factors of the tool alignment were analyzed emphatically. Through numerical calculation and analysis of the specific form of tool alignment error, a reasonable grinding wheel center alignment scheme was put forward. The wear law of grinding wheel was analyzed through process test, and a reasonable dressing method of grinding wheel was put forward.
