Algorithm for interference-free tool orientation planning in multi-axis CNC machining

The introduction of multi axis CNC machining tool orientations improve the flexibility of motion, but also brings problems such as tool interference and nonlinear errors. A tool orientation planning method for multi axis CNC machining is proposed. In this method, the Gaussian sphere is introduced to solve the reachable region, and is expressed in a reachable matrix. A tool orientation planning method based on the reachable matrix is proposed. Results show that tool interference free path can be achieved while ensuring higher machining accuracy and efficiency.
