The reasonability and validity of the method was testified by the coincidence of the simulation and the theory analysis under the motion mode of trapezoidal velocity and S-velocity profile.

Study on error online measurement for complex curved surface profile error of skew roller based on error separation technique;

This article mainly introduces a theoretical basis for Unified method of profile error measurement against large axles form of complex generalized helicoids,and uses the frequency domain Three-point method for Error Separation Technique(CEST) and error compensation technique in the method of profile error measurement.

In order to establish the theoretical model of data processing in profile error evaluation of sophisticated conicoid,an profile error evaluation method,which does not need to meet the small error hypothesis and does not use differential linearization,is presented.

Evaluation method of plane line profile error based on genetic algorithm and auto-spotting;

A new method for calculating the plane line profile error based on genetic algorithm and autospotting is proposed in this paper.

Under no change in hardware, controlling of contour accuracy is achieved in high speed two dimensional laser cutting system by modifying the interpolated data according to the contour error referred as controlling variable.
