Thermal hybrid machining processes

Abstract

This chapter describes thermal-type HMPs in which EDM as the primary process of material removal is combined with either a conventional machining/finishing process or with an electrolytic dissolution-based process for improved machining/finishing characteristics and workpiece surface integrity. This hybridization enables thermal HMPs to reduce processing times by 2 to 3 times when compared to their constituent processes while producing surface finishes up to 0.1 µm. Some of the important applications of thermal HMPs are as follows: drilling of micro-holes and the production of slits in quartz and glass, machining of metal matrix composites and ceramics, and dressing of grinding wheels. © The Author(s) 2016.
