Systems & Software

CNC & Machine Controls
The CNC (computer numerical control) system of a machine tool includes the control unit itself, as well as less visible parts of the motion-control system such as the servomotors, drives and axis positioning devices. These components are part of any CNC machine tool, but they might be bought separately and retrofitted later on older machines that are upgraded or refurbished. Also part of the control system are sensors that may allow 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.

Vector Programming Eases Five-Axis Aerospace Machining


Because the CNCs on this shop’s largest five-axis machining centers accept vector coordinates as program input instead of traditional G codes, critical jobs can be shifted readily from machine to machine.

The Need to Know Is Basic


An MTConnect-enabled monitoring system gives this shop a clear and simple picture of machine tool usage.

MTConnect Is For Real


Introduced at IMTS 2008, this communications protocol for CNC machines and other manufacturing equipment is already helping shops and plants implement effective machine monitoring systems. Although these "early adopters" are motivated by the long-term promise of enterprise-wide efficiency gains, their experience with pilot projects shows that benefits derived in the short term are substantial and worthwhile.
