CNC and Machine Controls

The CNC (computer numerical control) system of a machine tool includes the control unit itself, as well as the motion-control system such as the servomotors, drives and axis positioning devices. Also part of the control system are sensors that might enable the control to make certain real-time decisions during unattended or lightly attended machining processes. These can include probes for measuring the position of the part or machined features, as well as monitoring systems for detecting the presence of the tool or the force that is being exerted in the cut. Some CNCs offer conversational programming as an alternative to traditional G-code programming as well as open architecture for easier data sharing/communication between shop equipment.
