machine tool geometric error model, and gives the numerical control machine tool first order error expression model, this paper analyzes the model of the error term.
Main shaft rotary five axis machine tool swinging according to the design scheme of the error measuring error parameters identification example of. The dx, dy and dz items measured value error identification error model of the error parameters, and explains the design scheme of the error of measurement error parameters can be used in the model.
