Description
McGraw Hill Modern Machining Processes by PANDEY
Due to the nature of the raw materials being used in various manufacturing processes, there was a need for devising new machining processes. Modern Machining Processes covers new techniques that have evolved to meet the changing needs. Many industries use materials that are very brittle or extremely hard. Conventional machining processes depend on contact between the raw material and the tools used to modify them. But in some cases, this contact could cause damage either to the tool or to the material being processed. For instance, using traditional contact based tools on very hard materials like tungsten carbide might result in damage to the tool. On the other hand, brittle material like ceramic might be easily damaged if processed using traditional tools. Unconventional machining processes involve techniques that do not require direct contact between the tool and the material being processed. This book classifies these tools based on the type of energy used in the process. The first chapter is Modern Machining Processes: An Overview. This chapter also covers process selection. It explains the various factors that have to be taken into account while choosing a particular processing method. The book covers Modern Machining Processes in three sections. The first of these, covered in chapter two, is Mechanical Processes. This chapter examines techniques that make use of mechanical energy. It looks at ultrasonic machining, water jet and abrasive jet machining methods. The next chapter covers Electrochemical and Chemical Metal Removing Processes. This section covers techniques like electrochemical machining, electrochemical honing, electrochemical grinding, and chemical machining. The chapter, Thermal Metal Removal Processes, detail methods like plasma arc machining, neutral particle etching, electric discharge machining, hot machining, electron beam machining and laser beam machining. The book contains concise explanations of the various unconventional machining method
