机床定位误差是产生加工误差的主要因素,特别是在精密加工和超精密加工中更是如此。机床定位误差是指机床在规定的加工空间范围内进行定位的误差。影响机床定位误差的主要因素是机床的测量系统、伺服系统、滑板进给系统以及机床部件相互几何关系等。机床定位误差一般有两种性质不同的误差,即系统定位误差和重复定位误差。系统定位误差反映了机床定位的
Machine tool positioning error is the main factor in processing errors, especially in precision machining and ultra-precision machining even more so. Machine positioning error refers to the machine tool within the specified processing space for positioning error. The main factors that affect the positioning error of the machine tool are the geometric relationship between the measuring system of the machine tool, the servo system, the feeding system of the sliding plate and the parts of the machine tool. Machine positioning errors generally have two different nature of the error, that is, system positioning error and repeat positioning error. System positioning error reflects the positioning of the machine
