The Computer Numerical Controls (CNC) market is set to grow due to the demand of production efficiency. CNC machines have been a staple of manufacturers but they are now being paired with automation systems and simulation software to increase production. The addition of 3D printing machines onto the factory floor has also increased the demand of CNC machines, since they are used for the surface finishing of 3D printed objects. When implementing CNC machines there are some tips and best practices because even automated CNC machines need human supervision.
Background on CNC Machines
CNC machines were first developed and introduced between the 1940s to 1950s. They relied on punched tape or perforated paper tape for common telecommunication data storage technology. This quickly transitioned to analog and then eventually digital computer processing. CNCs rely on digital instructions from computer-aided manufacturing (CAM) or computer-aided design (CAD). The CNC machine then interprets the design from the CAM/CAD instructions.
CNC machines are now benefiting from automation to make more precise parts and are aiding emerging technologies by producing quicker parts. The video below describes how 3D printing and CNC machines are being used side by side.
