CNC Machines Have Been Used to Drill Holes, Cut Designs

CNC stands for "computer numeric control" and refers to many different manufacturing processes. Since the technology was developed in the 1970s, CNC machines have been used to drill holes, cut designs and parts from metal plates and do lettering and engraving. Grinding, milling, boring and tapping can also be done on CNC machines. Efficiency Aside from the need for periodic maintenance, CNC machines can operate almost continuously. One person can oversee the operation of several CNC machines at a time. Ease of Use CNC machines are easier for beginners to use than lathes and milling machines. Expanding Options Software changes and updates make it possible to expand the machine's capabilities rather than replacing the machine. No Prototyping New designs and parts can be programmed directly into a CNC machine, eliminating the need to build a prototype. Precision Parts made on a CNC machine are identical to each other. Reduce Waste CNC programs can plan the lay out of the pieces to be machined on the material to be used. This allows the machine to minimize wasted material. Source: ehow.com
