Cutting Tools
2.1 Introduction
Machining by cutting produces accurate parts by removing the machining
allowance in the form of chips by using cutting tools that are harder than the
workpiece and will penetrate it. Depending on the accuracy requirements,
hand tools, power-driven cutting tools, or common machine tools are used.
Generally, the machining system consists of the cutting tool, the workpiece,
and the machine tool. The machine tool is responsible for
• Application of the cutting power
• Guiding or limiting the tool/workpiece movements
• Controlling the cutting variables, such as the cutting speed, depth of
cut, feed rate, and lubrication ...
