trunnions—as a companion to its two other legacy four-axis Mitsui Seiki HMCs. “We have gained a lot of experience in titanium since then. This is another aspect of planning—we listen to our vendor resources about what they are seeing in the marketplace and the technology solutions that are truly working. We also visit the OEMs in our target sector and note what they have on the production floor or, perhaps more importantly, wish they had on the floor. Mitsui Seiki advised us on the comprehensive titanium-cutting solution, including tooling, such as the Ken- nametal Harvi cutters.” KT’s early-and-often planning approach might be in- tangible, but quantitative data are not, and the company’s clients evaluate KT’s part consistency, among other factors, in numerical terms. To that end, Tajirian and his team are continually looking for ways to improve part precision. The two CMMs—supported by the latest PCDMIS and CATIA soft- ware—and the other gaging devices in the cool, quiet quality

room get a healthy workout at KT engineering. The company is certified to both ISO 9001:2008 and AS9100C. Quality technicians measure part accuracies, monitor productivity gains, track all parts via a barcode system, and compute and appraise the trend analyses. For instance, a titanium hinge used in an aircraft wing assembly used to take 32 hours to produce; now it’s down to 18 on the five-axis trunnion HMCs. KT’s skilled machinists have always been able to hold required tolerences, but before those new HMCs were in place the part had to travel to and from five different machines, which increases the risk of going out of bounds with varying positioning values of each piece of equipment. Plus the extra physical handling added more unproductive time to the statistics. An unforeseen benefit: finer surface finishes are also being achieved, which translates to less bench time.

“The ample work envelope on the trunnion machine allows us to cut two parts out of the titanium block now, and cut five sides in one setup,” said Tajirian. “That has also improved our efficiency. As for the quality impact, the rigidity and accuracy are exceptional. On the bores we are achieving a plus or minus two ‘tenths’—better than half a thousandths,
