Is a FANUC R-30iB Plus a CNC control?

No. R-30iB Plus is a FANUC robot-controller family. FANUC CNC controls include product families such as 0i and 30i/31i/32i.

Does the robot controller replace the CNC control?

No. In a machine-tending cell, the robot controller and CNC control coordinate through a defined machine interface, but each controls its own equipment.

Automation controls

FANUC robot controllers

The robot controller coordinates arm motion, safety interfaces, I/O, programming and connected automation. Controller choice follows the robot generation and cell architecture; it is not interchangeable with the CNC control installed on a machine tool.

Controller planning questions

Which controller and software generation is approved for the selected robot?
What safety hardware, fieldbus, vision, auxiliary-axis and machine-interface options are installed?
Which cabinet format fits the available floor space and environmental conditions?
Who will own backups, access control, software revisions, training and recovery procedures?
How will the controller exchange cycle-ready, door, chuck, pallet, fault and reset signals with the machine?
