MACHINE CONTROLS In addition, the Dynamic Tool Load feature offers a new
control function for Okuma MU series milling machines, Klipp- stein said. “It’s targeted for aero because it’s for hard-to-cut materials like Inconel,” he said. “It helps with runout because
as the tool rotates it’s going to automatically adjust the fee- drate per insert blade. Let’s say you need to change a tool. It’s automatically going to change the rate for you—it equalizes the cutting force dynamically while the tool’s in motion. “The new algorithm does this, giv- ing you equal cutting force,” Klipp- stein said. “The goal is to increase tool life, and from the studies that we’ve done, it’s improved tool life by about five times for stainless, and about two times for titanium.”
Automating with Precision Much of the automation added
REDEFINING POSSIBLE From Powder to Polish
At General Carbide, our experienced team of applications engineers and metallurgists can help you develop the ideal tungsten carbide tooling for your stamping/lamination, general metal forming or fastener tooling application in aerospace & defense, energy, medical or motorized vehicles.

in aerospace CNCs revolves around precision machining. With the latest Heidenhain TNC 640 CNCs, aero ma- chinists can automate monitoring func- tions and eliminate some human factors in production, noted Julian Renz, TNC product specialist, Heidenhain Corp. (Schaumburg, IL). “With aerospace, automation becomes more important,” Renz said. “Our Advanced Dynamic Prediction [ADP] is a feature for better smoothing. This is an algorithm that if there are too many data points, it can fix it and it optimizes feed rates.” Automation can lessen or lower the need for operator intervention, particu- larly in monitoring functions, Renz said. Optimizing and smoothing techniques can remove chatter on the part. “Basically it’s our path control concept. Instead of splines, we use a tolerance band to connect the data points. It lets the user decide the width of the tolerances and the correspond- ing acceleration and jerk values are determined in the back of the control. Thus, you let the CNC stay within those parameters with our Control Contour Cycle; it’s called Cycle 32.” The new Advanced Dynamic Pre- diction also plays a role in the CNC’s look-ahead functionality, helping to
