Since it provides improved precision and repeatability that may be impossible to attain with ᴍᴀɴual techniques alone, Computer Numerical Control (CNC) technology has dominated the metal forming business in recent years. With so ᴍᴀɴy CNC technologies available, it might be challenging to tell them apart and what each one is used for. While CNC turning and milling have ᴍᴀɴy similarities, they also significantly differ from one another. Although CNC milling and CNC machining are almost interchangeable, CNC turning frequently yields products more quickly and economically than CNC milling. The cutting tool’s range of motion is the limit for CNC milling. Although CNC turning is less effective at material conservation, it offers more complicated design options and speedier production.
By gradually removing material from the workpiece with rotating multipoint cutting tools and computerized controls, CNC milling is a mechanical process that creates parts or components that are specifically created for each customer. These systems usually have three linear degrees of freedom. While the workpiece is held steady, they can move freely about the X, Y, and Z axes. Milling is better suited for prototyping and short production runs because the constrained dimensional operation slows down processing speed.
In the production process known as CNC turning, material bars are held in a chuck and rotated while a tool is being fed to the piece to remove material until the required form is attained. The technique, which involves eliminating material to get the needed shape, is known as subtraction machining. All of the work can be done from one side if the CNC turning center only has one turret. For even speedier operation, certain turning centers do, however, have both a main spindle and a sub-spindle. In this configuration, the workpiece is partially cut by the main spindle before being sent to the sub-spindle to complete the process on the component’s opposite side. Due to its speed, CNC turning processes are suitable for large production runs with short lead periods.
