CAM programming, like 3D modeling, requires knowledge and experience in running the program, developing machining strategies, and knowing what tools and operations to use in each situation to get the best results. It is also not an automatic operation that imports your CAD model and spits out the correct NC code. Note: CAM does not actually run the CNC machine, but just creates code for it to follow. When the two are used together, this is generally referred to as CAD/CAM. Some industrial standard desktop machines do exist with dedicated controllers for doing precise small work.ĬAM – Computer Aided Machining or Manufacturing – Refers to the use of various software packages to create toolpaths and NC code to run a CNC controlled machine, based on 3D computer model (CAD) data. A few will also accept standard G-code as input.

Others have their own closed command system and perhaps even dedicated CAM software. Some desktop machines may run a lot like a printer.

In general these are lighter weight, less rigid, less precise, slower, and less expensive than their industrial counterparts, but can do well for machining objects out of softer materials such as plastics, foam, and wax. On the industrial machines there is usually a sophisticated feedback system that constantly monitors and adjusts the cutter's speed and position.ĭesktop CNC – There are many smaller modelmaker-hobbyist style desktop CNC machines. The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions. But for more hobbyist types of machines, or with some retrofits, the computer can be an external PC. For larger industrial machines, the computer is generally an on-board dedicated controller. The machine can be a milling machine, lathe, router, welder, grinder, laser or waterjet cutter, sheet metal stamping machine, robot, or many other types of machines. CNC – Computer Numerical Control – Taking digitized data, a computer and CAM program is used to control, automate, and monitor the movements of a machine.
