The main purpose of the study is to investigate potentials of vertical machining centre to produce aspheric glass moulds. The use of vertical CNC machining centre is promoted in the study to make the process more flexible compared to dedicated aspheric generators used in optical industry. Glass moulds were rough ground and lapped using four diamond grinding cup wheels. Metal and resin bonded wheels were used in rough grinding and lapping operation with grit size of 151µm and 15µm respectively. Theoretical and experimental investigations of the grinding parameters and material behaviour that influence partial ductile mode have been discussed. Analysis encompasses the kinematics of the grinding process, characterization of grinding wheel to...
