AI Technical Summary
Existing virtual machine tool axis position calculation methods for five-axis linkage machining simulation suffer from insufficient versatility, poor simulation accuracy, and low linkage reproduction. They cannot be adapted to five-axis machine tools with different structures, and the simulation results differ from actual machining.
By retrieving the five-axis virtual machine tool model that matches the machining task, a machining coordinate system is created at the workbench node. The start and end rotation axes and machining coordinates in the CNC code are parsed. The total motion time is calculated in combination with the motion type. Interpolation calculation is performed to distinguish between rapid and linear motions. Real-time rotation axes and virtual tool coordinates are solved synchronously. Real-time axes are calculated line by line in a loop to generate a complete set of real-time axis sequences.
It achieves universal compatibility with five-axis machine tools of different structures, improves simulation accuracy and linkage reproduction, ensures that simulation data is consistent with actual machining parameters, and provides accurate support for machining process verification.
