ADAPTABILITY OF POLISHING DISK TO THE SURFACE OF AUTOMOTIVE DIES IN FLOATING POLISHING

摘要

The surfaces of automotive dies are complex, especially automotive panels are free-form surfaces. So, at present, automobiles dies polishing is mostly done through manual work. Studying floating polishing technology to develop a polisher to replace the manual work, therefore, is a target die manufactures are looking for. One important problem is how to make polishing disk accrete free-form surface of dies. So, based on analyzing the characteristics and engineering requests of automotive dies, the adaptability of polishing disk with several typical curved surface is studied, and the expressions of max limit of polishing disk, shape of surface and a sway angle of polishing disk are gained in the condition that the polishing disk adapts to the typical curved surfaces. The results offer a rule to design a series of floating polishing disk.
