MODELING AND EXPERIMENT RESEARCH ON INTERFERENCE BETWEEN LINKS OF A 6-DOF PARALLEL KINEMATIC MACHINE

Abstract

Abstract: A workspace based interference model of a 6-DOF parallel machine tool is established，which is expressed by a group of parameterized nonlinear equation. Using the numerical continuous method，the boundary of the solution set of the model is found out，and the one-order boundary describes the relation between the interference and the terminal pose intuitivily. Based on these analytic results and though controlling the extra freedom of the machine tool，the link(sub-chain) interference is avoided effectively and the security of the operation of the machine tool is assured.

Key words: 6-DOF parallel kinematic machine Interference between links Parameterized nonlinear equation Numerical continuous methods, Handling stability, Integrated structural contribution coefficient, Multi-objective optimization, Ride comfort, Variable selection
