Dual Quaternion Interpolation Algorithm in Five-axis CNC System with High Speed and Precision Machining
High speed and precision machining technologyl,2,3 have been rapidly adopted in five-axis CNC system for their high productivity.The design of trajectory generation and control algorithms plays a crucial role in realizing the accuracy requirement for high speed feed motion.Most interpolation algorithms for five-axis CNC machining are focused on studying techniques to design position,orientation,and feedrate curves in such a way using iso-parametric correspondence as to avoid excessive angular velocities.However,it is difficult to guarantee such correspondence.To help alleviate such difficulties,this paper presents a new interpolation algorithm to five-axis CNC tool path generation for sculptured surface machining.Interpolation algorithm using dual quaternion has several advantages over the algorithm of interpolating translation and rotation independently and then combining the results.The effectiveness of the proposed interpolation algorithm is verified in Matlab.The results show the velocity,acceleration and jerk of five-axis machining can smooth without losing machining accuracyand surface quaffty.
