The first CNC machine was developed in the early 1940s and 50s. At that time, it relied on the technology of common telecommunication data storage, which was called “punched tape” or “perforated paper tape”. An electromechanical device that manipulates tools of the machine shop by using computer programming inputs is known as CNC machines. The word CNC stands for Computer Numerical Control. This machine represents one of the two common methods, 3D printing technologies like SLS.SLM, SLA, and FDM, etc. from digital software files to generate prototypes. Nowadays, the latest CNC machine, precision CNC machining China is trending all over the industries. From the molding of hardware to the modern digital print of fabrics, CNC machines are ruling now.
How CNC machine works?
Generally, CNC machining is the best way to transform a stock material piece like a block of plastics and arrive at the final product by the process of controlled material removal. It is typically a prototype part. Correspondingly. Another prototype development technology the 3D printing FDM, CNC machining relies on the digital instructions Computer-Aided Design, CAD or Computer-Aided Manufacturing, CAM file like 3D Solidworks. The design is interpreted by the CNC machine as instructions for cutting prototype parts.
To control the machine tools, the ability to program computer devices advances rapidly the productivity of the shop by automating the technical and labor highly intensive process. Moreover, the automated cuts of CNC machines improve the accuracy and the speed both with which the prototype parts can be easily created. The CNC machining processes often require the multiple tools use to make the desired cuts accurately. For instance, different sized drill bits. Commonly, this machine combines tools into common cells and units from which machines can draw. The CNC machine is an automatic accurate machine because it is dealing with computer programs.
Types Of CNC Machines:
Typically, there are two general categories of CNC machines.
It works by spinning the bit of drill and the movement of bit. Its contact with a stationary block of stock material.
The inverse of the drill is lathing that spins the material block against the drill bit. Typically, this makes contact with the materials by moving a cutting tool until it touches the spinning material; progressively.
- Milling machines:
It is one of the most common CNC machines and has great usage. It involves the rotary cutting tools used to remove material from the stock unit.
- Electrical or chemical machining:
There are several novel technologies, use specialized technologies for material cutting. For instance, it includes electrochemical machining, electron beam machining, photochemical machining, electrical discharge machining, and ultrasound machining, etc. Mostly these technologies are specialized highly and use in special cases for the mass-production by the involvement of a particular type of material.
- Other cutting mediums:
There are many other novel technologies of different mediums use to cut the material. For example, it includes oxy-fuel cutting machines, laser cutting machines, and water-jet cutting machines, etc.
