What Is Machining?

Machining is a subtractive manufacturing process that involves removing material from a workpiece using various cutting tools such as lathes, mills, and drills. This method is essential for achieving the desired shape and dimensions of components, especially when high precision and repeatability are necessary (source).

Core Concepts and Definitions

  • Machining: The process of material removal to create precise parts (source).
  • Machinist: A skilled operator who utilizes machine tools to manufacture parts (source).
  • Machine Shop: A facility equipped with machine tools, either as a standalone entity or part of a larger operation (source).

Common Machining Processes

Machining encompasses a variety of processes, each suited for specific applications. The main types include:

  • Turning: Utilizes lathes to create cylindrical components (source).
  • Milling: Employs rotating cutters for versatile material removal across multiple directions (source).
  • Drilling: Establishes or refines holes using drill presses (source).
  • Boring: Increases the size of existing holes with precision (source).
  • Reaming: Smoothens hole walls to achieve fine tolerances (source).
