Machining: An Introduction
In terms of annual dollars spent, machining is the most important of the manufacturing processes. Machining can be defined as the process of removing material from a workpiece in the form of chips. The term metal cutting is used when the material is metallic. Most machining has very low set-up cost compared to forming, molding, and casting processes. However, machining is much more expensive for high volumes. Machining is necessary where tight tolerances on dimensions and finishes are required.

 
The Machining section is divided into the following categories:
  1. DRILLING:

     
  2. TURNING:

     
  3. MILLING:

     
  4. GRINDING:

     
  5. CHIP FORMATION:
