TECHNICAL DEFINITION

Computer Numerical Control (CNC) is an automation technology where machine tools (e.g., mills, lathes, routers) are controlled by pre-programmed computer software, executing precise, multi-axis movements and operations on workpieces based on G-code instructions, enabling high-precision and repeatable manufacturing.

BACKGROUND

Design for manufacturability (DFM), also known as design for manufacturing, is the engineering practice of designing a product to reduce the cost of its manufacture and to make its manufacture easier, and often the two aspects are intertwined. Common factors that affect manufacturability include the type of raw material, the form of the raw material, dimensional tolerances, and secondary processing such as finishing.
