It improves material removal and minimizes cycle time by automatically optimizing the cutting feedrate based on the actual spindle load. Courtesy: Fanuc FA AmericaFanuc Factory Automation America ( Fanuc  FA America) and Jerry Scherer, engineer with  Fanuc  FA America, have been awarded a patent 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.

Fanuc FA America's 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 workpiece 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.

This CNC adaptive control system is the base technology in  Fanuc  FA America's iAdaptS solution that improves material removal and minimizes cycle time by automatically optimizing the cutting feedrate based on the actual spindle load. Additionally, integration of the iAdaptS software solution within the CNC now eliminates the need for mounting hardware, simplifying installation while improving the capabilities of the original iAdapt product. The original iAdapt product introduced the concept of roughing cycle productivity to CNC customers. The "On Demand" control feature simplified the use of the adaptive control by making it easy to setup and operate. iAdaptS extends tool life by keeping roughing tools fully loaded, putting the heat into the chips rather than the part. As a result, there are fewer minor stoppages which further increases productivity and reduces labor costs.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
