AI Technical Summary
In existing technologies, the mesh calculation efficiency of ball end mill multi-axis machining is low, and the cutting height calculation is poorly adapted to the geometric characteristics of the ball end mill, resulting in low accuracy of surface morphology generation.
A dynamic discrete domain trimming method is adopted to generate a high-density continuous discrete tool position sequence through spline interpolation, establish a high-resolution Z-Map discrete mesh model, and use a dynamic axis-aligned bounding box algorithm to lock the effective calculation area. Combined with Boolean subtraction operation, the ball end mill cutting process is accurately simulated.
This improved the accuracy and computational efficiency of surface morphology generation, ensuring the accuracy and completeness of simulation results and achieving high-quality surface morphology generation.
