Research on Nonlinear Error Analysis and Overproof Processing Method in Five-axis NC Machining with Dual Turntable

摘要

As for the widely used five-axis NC machine with dual turntable,this paper constructs the kinematics mathematic model and finishes solving the machine kinematics formula on the basis of workpiece coordinates system.On the basis of detailed discussion on the effective method for calculating nonlinear error,this paper provides the analysis and calculation and processing procedure for overproof.By processing cutter location (CL) data,the validity and feasibility of the method is tested correct by simulation.Accordingly,this paper provides an inerrable basis for the overproof processing method for design of the general postprocessing system.
