CNC (Computer Numerical Control) machining is a manual process that coincides with a computer-generated system. Computer codes are pre-programmed to cut, bend, or fasten materials. A CNC machining process promotes consistency and speed within the workplace.
A fully manual process that does not use a computer software program requires an operator to self-guide all of the materials that are being manipulated. An operator will need to consider the positioning of the raw materials that they are working with and will be responsible for measuring surfaces and guiding each tool that is used during operations.
