The answer is simple. In several industries, hard and brittle materials like tungsten carbide, high speed steels, stainless steels, ceramics etc. For example, tungsten carbide is used for making cutting tools while high speed steel is used for making gear cutters, drills, taps, milling cutters etc.
If such materials are machined with the help of conventional machining processes, either the tool undergoes extreme wear while machining hard workpiece or the workpiece material is damaged while machining brittle workpiece.
This is because, in conventional machining, there is a direct contact between the tool and the workpiece. Large cutting forces are involved and material is removed in the form of chips.
Huge amounts of heat is produced in the workpiece. This induces residual stresses, which degrades the life and quality of the workpiece material. Hence, conventional machining produces poor quality workpiece with poor surface finish if the workpiece is made of hard and brittle material.
To overcome all these drawbacks, we use unconventional machining processes to machine hard and brittle materials. We also use unconventional machining processes to machine soft materials, in order to get better dimensional accuracy. Unconventional machining processes can be broadly classified into several types based on four main criteria. The classification of unconventional machining processes is given below:. Each unit contains two mark questions and answers, review questions.
Model question papers are added at the tail end of this book. With these features, we sincerely hope that this book would serve as a valuable text for the students.
