Basic point-to-point (P2P) interpolation for linear toolpath causes motion stops at each corner and excites structure vibration. Instead of inserting blending spline curves and solving feedrate planning between linear segments, non-stop feed motion is achieved in real-time by using the approach. Based on kinematic equations and pulse commands of motion axes, the length of FIR filtering is determined to respect corner tolerance and kinematic constraints of the drives simultaneously. Rather than adding the dwell time in filter-based feedrate planning, two-axis motion is realized by evaluating corner speed and matching the same length of FIR filters. Simulation studies and experiments results are provided to validate the effectiveness of the presented technique and improve cycle time and contouring performance. ? 2021 IEEE. |
