As a manufacturer, the goal has always been to increase productive efficiency; to adopt manufacturing technologies that streamline and shorten processes, maximize output and minimize costs. The modern-day CNC machining technology is the answer to it.
What exactly is CNC machining? And what are the benefits it brings to the manufacturing process? Right here in this article, we go over everything you need to know about CNC machining.
Computer Numerical Control or CNC machining is a digital manufacturing process. A pre-programmed computer system controls the tools and machinery used in production, fully automating the process. Thus, it dispenses with the need to employ people to operate machining tools. CNC machining is evolved from Numerical Controlled (NC) machines.
Owing to CNC machining techniques, it has now become possible to manufacture intricate designs in parts and products; the same would have been challenging if done manually, using traditional production techniques.
A CNC system looks like an ordinary computer system; however, it uses dedicated consoles and software programme to produce machined parts. The prototypes are designed using CAD software, which are then fed into the system. The 3D models describe the physical properties and dimensions of the machined parts in detail. These are written code controls. CAD files are written in G-code and translated using a CAM software.
When the system is switched on, the software sends the appropriate functions to the tools and machines. They are also capable of switching digital functions. The code controls the entire manufacturing process, from directing the cutting head to adjusting variables such as RPMS, cutting speed, and voltage. CNC machines function like a robot. CNC machining is a subtractive manufacturing process. It involves cutting 3D products out of a solid block.
There are many types of machines used in CNC machining. Listed below are the most common ones.
CNC machining uses prototypes to produce a range of plastic and metal parts. This ensures uniformity and precision in design. This well-oiled system speeds up the production process, thereby increasing efficiency. CNC machining optimizes material usage and reduces wastage.
The automation in production further saves time and money. If we do a cost-comparison of CNC fabricated parts, whether produced in volume or as custom designs, they work out cheaper.
