【Abstract】 Multi-axis CNC mchining center are of both structural complexity and multi-axis kinematics. In order to tackle conjunct movement of axes in virtual enviromnent, geometric model and kinematics of multi-axis CNC machining center are studied, and generic modeling method based on object-oriented technology is investigated. Taking CKX5680 as a study case, virtual simulation model of multi-axis CNC machining center is established with consistency of geometric model and conjunct movement of axes using OpenGL. The developed method lays foundation to NC cutting simulation and collision detection.更多还原
