Machining characteristics of fluorophlogopite glass ceramic

Fluorophlogopite glass ceramic and medium carbon steel were turned on lathe. Machining surface of glass ceramic and tool wear surface were observed with scanning electronic mecroscope. Surface roughness was measured with profile meter. Three cutting force components, including axial force, radial force, and major cutting force, were measured with Kistler piezoelectric dynamometer. Compared with metal materials, fluorophlogopite glass ceramic presents its machining characteristics. Layer structures could be observed on fluorophlogopite glass ceramic turning surface. There exists rapid wear of high speed steel tool during machining process of fluorophlogopite glass ceramic. Surface roughness value become bigger if cutting coolant is applied to machining processes. Radial force has the biggest value among three cutting force components.
