Grinding Model of Processing Aspheric Parts by Bending Method

Article Preview

Abstract:

A new method of processing optical aspheric parts by of bending and forming is presented, and the processing is line contact. The grinding principle is given of the bending and forming method. Based on the Preston equation, the grinding conditions is put forward to the bending and forming method. The function of the pressure and the relative velocity on the any point of at the processing surface are made. The material removal function is deduced about the bending and forming method. The experiments shows the grinding average error is 0.0272mm using solid abrasive on parabolic parts, and the maximum error is 1.0038μm using abrasive belt on hyperboloid parts.
