AI Technical Summary
Existing technologies fail to effectively identify and compensate for systematic tilting errors caused by the directionality of surface texture when connecting CNC machining and grinding processes, resulting in step-like abrupt changes at the interface of the machined surfaces, which affects the machining quality and continuity.
By collecting texture data between the machine tool spindle and the worktable, the angle between the probe trigger force direction and the normal of the workpiece surface and the groove direction angle are extracted. The tilt angle is fitted by the least squares method, the normal direction of the machining surface is dynamically adjusted, the contour fitting gap is optimized, and the height difference and tangential offset at the interface are eliminated by iteratively correcting the transverse displacement and coordinate system alignment of the probe trigger point.
It achieves high-precision matching of the machining surface contour and effective elimination of step abrupt changes, improving the overall quality and efficiency of CNC machining and grinding processes, and ensuring continuity and smoothness during process switching.
