Computer Numerical Control (CNC) and Mastercam Training
Computer Numerical Control (CNC)
The concept of computer-controlled machining began in 1967. CNC machines became recognized as the industry standard. With the development of CNC machines like milling machines and lathes, G-Codes are still used as a means of control, but are now designed, controlled and conducted through computers. Machines that feature parametric programs allow the operator to make adjustments on-demand and make it easier to access important system parameters.
CNC machining allows for greatly improved accuracy, efficiency, productivity and safety over other forms of metalworking equipment. With CNC machining equipment, the operator is placed less at risk and human interaction is significantly decreased. In many applications, CNC equipment can continue to operate unmanned over the weekend. If an error or a problem occurs, the CNC software automatically ceases operation and calls or pages the off-site operator.
CNC Software, Inc. is one of the oldest developers of PC-based computer-aided design / computer-aided manufacturing (CAD/CAM) software. Mastercam, CNC Software’s main product, started as a 2D CAM system with CAD tools that let machinists design virtual parts on a computer screen and also guided computer numerical controlled (CNC) machine tools in the manufacture of parts.
Mastercam’s comprehensive set of predefined toolpaths—including contour, drill, pocketing, face, peel mill, engraving, surface high speed, advanced multiaxis, and many more—enable machinists to cut parts efficiently and accurately. Mastercam users can create and cut parts using one of many supplied machine and control definitions, or they can use Mastercam’s advanced tools to create their own customized definitions.
