As outlined by Universal Technical Institute in their article “How a CNC Mill Works,” CNC milling is a precise machining process that follows a structured workflow, from CAD design to final machining. This process allows manufacturers to create highly detailed and accurate parts using automated milling machines.
How CNC Milling Works: Step-by-Step
- Design & Programming – A 2D or 3D CAD model is created and converted into a CNC-compatible format using CAM software.
- Machine Setup – The operator prepares the worktable, work-holding device, and milling tools.
- Program Execution – The CNC machine follows programmed instructions to cut, shape, and refine the material.
- Precision Cutting – The rotating cutting tool moves in multiple directions and along various axes to create intricate designs.
- Final Processing – The machine continues shaping the material until the part meets exact specifications.
CNC milling machines are available in horizontal and vertical configurations, with cutting tools rotating at speeds of thousands of revolutions per minute (RPM). This process is used to refine pre-machined parts or shape raw materials from start to finish with exceptional accuracy.
