The use of CNC or computer numerical control equipment in milling and turning provides a level of precision and control that is simply not possible with manual turning and milling. Through the use of a computer program that controls the precise movements of the cutting tools on the equipment, parts can be produced to tight tolerances.
Unlike other types of machining, the use of CNC milling and turning is also faster than manual options. The equipment can operate on a continual basis, something that is not possible when the operator has to manage and control the system. Additionally, the entire system can operate independently of the need for human adjustments, which keeps the production at a higher rate.
Another benefit to consider is the lower waste involved in prototype development as well as full-scale production using CNC milling and turning. Once the program has been developed, it can be stored and run as often as necessary, producing exact copies of the CAD/CAM drawing that are identical to each other and to every other part produced on other runs as well.
Differences In CNC Turning and CNC Milling
CNC milling is a process where the workpiece remains stationary in the equipment and the cutting tools, and the milling table will move as per the programmed information.
The opposite is true for CNC turning, where the workpiece is rotated while the cutting tool traverses the workpieces. Turning is most often used when there is a need to shape the exterior of a cylindrical workpiece in symmetrical ways or when there is a need to bore into the workpiece.
Milling, on the other hand, can be used to create unique shapes and features on the exterior of the surface of the workpiece. It can be used to cut radial corners or to create specific shapes of pockets in the workpiece.
Companies that specialize in CNC milling and turning will assess the design and choose the ideal process for effective, efficient and lowest possible cost production options.
