Abstract: Colloid jet polishing (CJP) is a new technique for the ultraprecision machining of aspheric surfaces, especially for the ultrasmooth surfaces machining of small-radiused concave surfaces and freeform surfaces. In this paper, a colloid jet polishing equipment with 5 axes, four of which perform linkage movement was developed. According to characteristic of colloid jet polishing, NC interpolation algorithm for rotary symmetric aspheric based on this equipment was researched. The derivation process and computer si…
