Fanuc FA America awarded new patent


Increasing machine tool productivity is critical for moldmakers in their bid to be globally competitive. To assist with that goal, FANUC Factory Automation America (FANUC FA America) and Jerry Scherer, engineer with FANUC FA America (, have recently been awarded a patent (US 8, 135,491 B2) for the development of their CNC Adaptive Control System for on-demand integrated adaptive control of machining operations. This system was developed to increase machine tool productivity with FANUC FA America’s iAdaptS adaptive control solution.

The newly patented CNC Adaptive Control System measures the present value of the spindle load and then compares this value to a present value of a target spindle load. The adaptive controller is configured to control the feed rate of the machine tool relative to the work piece to maintain the present value of the spindle load approximately equal to the present value of the target spindle load using one or more calculations of the first feed rate value, the first feed rate dither adjustment value and the second feed rate dither adjustment value....
