  Hybrid Machining Processes

15.1   INTRODUCTION

Advanced materials play an increasingly important role in modern manufacturing industries, especially in aircraft, automobile, tool, die, and mold-making industries. The greatly improved thermal, chemical, and mechanical properties of these materials such as improved strength, heat resistance, wear resistance, and corrosion resistance are making conventional and nonconventional machining processes unable to machine them economically. Table 15.1 compares the nonconventional machining methods regarding their removal rate, accuracy, surface finish, power needed, and the capital cost. The technological improvement of these machining processes can be achieved by combining different physicochemical ...
