Trapezoidal acceleration based feed profiling has been widely used in high-speed motion generation for machine tools. Although it delivers continuous acceleration with limited jerk, the profile cannot be tuned to avoid exciting particular modal frequencies and eliminate residual vibrations. This paper proposes a novel FIR based trajectory generation algorithm that generates continuous trajectories with confined contouring errors suitable to deliver rapid motion with attenuated residual vibration. Specifically, fundamental formulation is presented to interpolate circular paths with confined contouring error while accounting for the FIR filter dynamics and path kinematics. Proposed method has been validated though simulations, and it shows significant improvement towards minimizing cycle time and accuracy of contouring multi-segmented Cartesian tool paths.
