Turning is one of a variety of subtractive manufacturing processes used to create detailed parts and components. In computer numerical controlled (CNC) turning, this automated process relies on a chuck to hold and rotate bars of material. As this occurs, a tool is fed to the piece that removes excess material to develop features. A turret is then used to move the bar of raw material and remove material until the programmed result is achieved.

Why is CNC Technology Important?
CNC technologies have enabled manufacturers to automate a variety of complex machining processes. While manual machining requires highly skilled machinists who can follow designs, CNC machining offers superior process accuracy and better part-to-part repeatability thanks to its ability to follow digital Computer-Aided Manufacturing (CAM) instructions generated from Computer-Aided Design (CAD) files.

Automated CNC technologies have enabled the mass production of part and components within very close tolerance limits, ensuring that parts generated from the same design may be used interchangeably in the assembly of automobiles, aerospace equipment, industrial machines, and much more. Lower defect rates and faster production ultimately lower the per-unit cost of each part, offering significant savings on high-volume production.

Difference Between CNC Milling and CNC Turning

CNC milling and CNC turning are both subtractive manufacturing processes used to cut material away from a stock workpiece to realize a pre-programmed design.

  • CNC milling. CNC milling rotates cutting tools on multiple axes around a stationary workpiece to remove material in accordance with the specified design.
  • CNC turning. CNC turning rotates the workpiece itself on a lathe while the cutting tool or tools move horizontally on a turret to make cuts and remove material.
