GE Fanuc has added new features to its high-end Series 30i-Model A and Series 31i-Model A CNCs to increase productivity, and to further enhance machine and operator safety.

GE Fanuc has added new features to its high-end Series 30i-Model A and Series 31i-Model A CNCs to increase productivity, and to further enhance machine and operator safety.

A new Path Table Operation feature on the GE Fanuc Series 30i-Model A and Series 31i-Model A simplifies the programming of interlinked axes.

All related axial positions are entered as two-dimensional arrays.

The CNC interprets these path tables to control all the rotational and linear axial movements accordingly.

A new 3-D Interference Check feature on the GE Fanuc Series 30i-Model A and Series 31i-Model A /A5 helps to prevent machine collisions.

It enables the definition of all objects in machining that may cause a collision.

The rotary tool, the work piece and the table and clamp, for example, are all defined within a right-angled volume.

The controller will then use this 3-D information to avoid collisions.

This feature on the Open CNC Series 300i Model A and the Series 310i-Model A /A5 can be customised by a Machine Tool Builder (MTB).

This 3-D inteference machine safety feature complements Dual Check Safety, which is designed to protect the safety of the machine-tool operator.

The MTB has to comply with standards such as safety category 3 (EN 954-1).

In GE Fanuc systems, Dual Check Safety is an integrated function on Series 30i/31i/32i CNCs that uses sensors to monitor access to the machine as well as all servo and spindle movements.

The top-of-the-range GE Fanuc Series 30i-Model A controls up to 10 paths, 32 axes and 8 spindles, while the 31i-Model A controls up to 4 paths, 20 axes and 6 spindles.

With a compatible upgrade path from earlier models, they also offer an increased number of simultaneously executed CNC programs, enhanced surface finishing capabilities, as well as increased speed and enhanced ease-of-use.
