摘要：
Aiming at the need to manually plan empty run during multi-spindle 5-axis processing, an automatic empty run trajectory planning method was put forward. On the basis of multi-spindle machine tool kinematics modeling, aiming at the cutter location point trajectory and generating of tool axis vector, the cutter location point trajectory based on shortest path and collision-free tool axis vector planning were proposed respectively, so that the empty run planning was converted into a parameter-optimization problem. To simplify collision detection, a two-level intersection detection algorithm was proposed. The objective function of empty run planning was established by weighting coefficient method, and it was solved by genetic algorithm, so that a flexible ideal trajectory with no collision, shortest movement time, smallest change of rotation axis angle and shortest ending-trajectory was planned. In the simulation platform established by Vericut, the feasibility and effectiveness of the method had been verified. The empty-run trajectory planning for complex work-piece could be realized by decomposing trajectories and calculating intersections with work-piece edge for many times. © 2022, Editorial Department of CIMS.
