CAM software for production is focused on programming machining centers, lathes and turn/mill machines to execute a variety of typically simple machining operations in the most efficient sequence possible. Milling, pocketing, slotting, drilling and OD and ID turning are all examples of operations that might apply to the machining cycle for a particular production part. CAM software for production also often features tools for software automation, or knowledge-based machining. Many of the decisions necessary to machine a production part are repetitive, involving assigning particular tools and parameters for particular varieties of drilled holes or milled features. CAM software with some knowledge-based functionality can allow the programmer to input his “knowledge” about tool, process and parameter preferences for certain fundamental types of machined features, so that the software can recognize those features in the future and program them automatically, saving the programmer time.
