Different from material removal mechanism in metals, the main form of material removal of ceramics is brittle fracture removal. Previous studies on fracture mechanics for brittle materials basically do not involve cutting temperature, and only static crack systems are discussed, without considering the kinetic energy of crack extension; however, in real turning processes, the problem of crack extension...
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...
