AI Technical Summary

Technical Problem

Existing technologies cannot achieve six-axis simultaneous machining of complex castings, resulting in low machining efficiency and insufficient precision.

Method used

A six-axis grinding system is adopted. By establishing a six-dimensional coordinate system model, the XYZ axes are defined as Cartesian coordinates, the C and B axes rotate in a specific plane, and the A axis rotates around the X axis. The mapping relationship between the three spatial axes ABC and the three XYZ axes is established. The method of determining the arc using three non-collinear points is used to calculate the coordinates of the center and the radius. The six-axis circular interpolation is realized by using a homogeneous transformation matrix.

Benefits of technology

It achieves high efficiency and high precision in six-axis linkage machining of complex castings, ensuring the accuracy of grinding and the smoothness of cutting edges, and improving machining efficiency and precise control.
