Design and Simulation of Virtual Axis Hybrid Abrasive Finishing and Polishing Machine Tool

摘要

To solve the problem of insufficient working space of abrasive finishing and polishing device with large free-form surfaces, a flexible finishing and polishing system with 5-DOF is designed, which combine the 3-TTT parallel mechanism and the principal axis rotating around two axes. Modeling is based on characters. Abrasive finishing and polishing machine tool's concept design is done with Pro/E, The system is described and dynamics simulation with Lagrange method and d'alembert's principle. The simulation result provides grounds for numerical values of Virtual Axis Hybrid Polishing Machine Tool's real-time control and prototype machine design and new reason of applying parallel connection structure in polishing process.
