Cutting characteristics of glass milling.

Improvement of cutting efficiency in the roughing and the finishing processes.

Abstract

An improvement of cutting efficiency in glass milling is discussed. In cutting tests, characteristics of brittle fracturing are observed in the roughing and the finishing process to improve the cutting efficiency. As the result, it is shown that an axial length of fractured area is less than 0.01mm in roughing process. And the fractured area can be removed with finishing process at a axial depth cut of more than the axial length of farctured area.
