The primary purpose of filing is removing excess material.

• Material Removal: Filing is a crucial process in many metalworking applications. It involves using a file (a tool with multiple cutting edges) to remove small amounts of material from a workpiece.
• Shaping and Finishing: Filing is used to:
  • Shape the workpiece to the desired dimensions and contours.
  • Smooth surfaces after other machining operations (like sawing or turning).
  • Remove burrs and sharp edges.
  • Prepare surfaces for further finishing (like polishing or painting).
