Founded in Massachusetts in 1983, CNC Software, Inc. is one of the oldest developers of PC-based computer-aided design?/?computer-aided manufacturing (CAD/CAM) software. They are one of the first to introduce CAD/CAM software designed for both machinists and engineers. 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. Since then, Mastercam has grown into the most widely used CAD/CAM package in the world.[2] CNC Software, Inc. is now located in Tolland, Connecticut. 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. Mastercam also offers a level of flexibility that allows the integration of 3rd party applications, called C-hooks, to address unique machine or process specific scenarios. Mastercam's name is a double entendre: it implies mastery of CAM (computer-aided manufacturing), which involves today's latest machine tool control technology; and it simultaneously pays homage to yesterday's machine tool control technology by echoing the older term master cam, which referred to the main cam or model that a tracer followed in order to control the movements of a mechanically automated machine tool.
