CAM Software is used to generate machining programs corresponding to part designs. Short for “computer-aided manufacturing,” CAM creates these programs for CNC machine tools including machining centers, lathes and EDM machines. Sometimes, machining programs can be written and input manually, right at the machine’s control. However, if the workpiece geometry is at all complex, or if the machined features are numerous, then generally CAM software is essential for generating the program both accurately and quickly. In general, CAM development has proceeded along two different tracks. Geometry-based CAM systems used in die/mold machining and other applications focus on complex milled geometries. Algorithms provide specific and efficient ways for machining complex geometries with both high precision and long tool life. By contrast, feature-based CAM systems are generally used in the production machining of geometrically simpler components. These latter CAM systems are often engineered to automate otherwise repetitive programming tasks such as assigning similar tools to similar features.
