Development on Shape-Adaptive Compliant Tool System

Abstract

A new shape-adaptive compliant tool system is developed in this essay, which can be effectually integrated with industrial robots and five-axis NC machines. The main principle of the above compliant tool system can be described as follows: a passive servo mechanism of bi-directional rotating sphere hinge, working with the robots to control the tool-path which can meet the requirements of the adaptive capability on free-form surfaces. The normal polishing force could be controlled by the designed linear stepping motor and column helix spring system. The virtual prototyping of the tool system is created in ADAMS, and used to take the simulating experiments on workpieces which have typical free-form surfaces. The experimental results indicate that the tool system developed in this essay performs well on shape-adaptive capacity on free-form surfaces.
