Computer Numerical Control (CNC) machines are used to create product prototypes based on software, like 3D printers. There are two main types of CNC machines that you can use for an application depending on your needs: conventional machining or novel machining. Based on the type of CNC machinery, you’ll need different parts such as CNC cutting bits or drill bits.
Conventional Machining
Conventional CNC technology will use three main types of tools. Drills are frequently utilized, which operate by spinning drill bits that contact pieces of unformed stock material. Lathes are also used, which raise the material up toward the spinning drill bit.
Milling machines are the most commonly used conventional CNC machines. They use rotary CNC cutting bits to remove material from the unformed material.
Novel Machining
Novel CNC machining technologies take advantage of certain specialized techniques to shape materials. These can include electrochemical machining, ultrasonic machining, electron beam machining, photochemical machining, and electrical discharge machining. These techniques are often used to accommodate mass production of prototypes using a specific type of material.
There are also other types of cutting mediums that novel technologies can use to cut materials, including plasma cutting machines, oxy fuel cutting machines, laser cutting machines, and water jet cutting equipment.
Which Is Better: CNC Machining or 3D Printing?
The answer to this will depend on the requirements of the application. Typically, CNC machining is used for more industrial applications to product prototypes from a variety of materials, seeing as 3D printers can only work with certain types of materials whereas CNC machines can work with many more. Novel CNC machinery is also frequently manufactured specifically for use in manufacturing processes in niche industries.
Ultimately, CNC machinery offers more versatility for a wide range of manufacturing processes and is still the ideal process for generating prototypes.
