The Fagor CNC 8070 control system is based upon an industrial-hardened Windows operating system running on an XP-embedded platform. This allows the integration of a host of online software configurations allowing the control system to work as an open architecture system. The control system is designed for use with digital servo systems, high-speed motors and linear, as well as rotary feedback systems. In addition, true five-axis machining compensation is a standard feature.

This solution increases productivity while maintaining part finish accuracy. Optimizing block processing time and analyzing the tool path in advance with high-speed block look ahead results in optimum part finish. The predictive control feature applies the right acceleration control for each machining operation causing the toolpath transition to become smoother. Mechanical stress is further minimized by applying post-interpolation filters that eliminate the resonance frequencies common to high speed machines.

CAD/CAM generated programs for molds and dies can be large and can require a specific CNC system treatment to obtain the maximum speed with the desired precision. The solutions implemented in the system to process CAD/CAM-generated programs consist of the combination of splines and polynomial transitions as well as the interpretation of the NURBS format. All this helps achieve high-feed-rate machining while maintaining the accuracy and decreasing execution times.

Ethernet communication helps set up the CNC as another node within the computer network and exchanges data with other departments. The control is capable of executing, through Ethernet, a program residing on another PC.

The conversational programming editor is said to make the CNC easy to operate and its intelligent profile editor creates profiles without the need for complex calculations. In addition, the CNC comes equipped with a 10″ or 15″ high-resolution, TFT LCD color screen.

The drives communicate with the CNC via digital servos making it possible to add more drive modules because they do not require additional cables or additional hardware expansions at the CNC. The controller offers remote CAN I/O, modules of inputs, outputs and counters that may be placed in strategic locations of the machine depending on the requirements of the application. High accuracy absolute linear and rotary feedback systems are designed to offer plug and play integration to the system.
