This paper analyzes the 21 original geometric errors of machine tools and the resulting coupling effects, namely geometric composite errors, and then arrives at the conclusion that the key point of error compensation for CNC machine tools is error value, a function of command position. And it also points the errors can be decoupled into error components of each axis-direction. Therefore, according to the consistency of the geometric composite errors, the decoupling algorithm of the geometric composite errors is researched, and decoupled model is proposed which is not only simplifies the complexity of the geometric model, but is also easy to implement error compensation.
