AD&P; > September 2014 > NOTABLE 12 The ROMER Absolute Arm was already the easiest to use portable measuring arm, so how did we make it even better? By observing how our users interact with it and further enhancing the ergonomics and ease of use. With redesigned hand positions, sensory feedback and re-engineered articulation at the wrist, you'll speed thorough inspections even faster than before. Because making shop fl oor inspection more effi cient is what a ROMER arm is all about. Visit www.HexMet.us/adpRomer or call 855.443.9638 for more information. THE FASTEST AND EASIEST JUST GOT BETTER To view a demo, scan this code or visit www.HexMet.us/adpRomerv. cutter's feedrate is increased from 1,656 mm/min to 1,826 mm/min (due to the increased number of inserts used). On an annual basis, they are saving 1,431 hours. And from a fnancial standpoint, the annual savings are on the order of £75,000 (which is in the vicinity of $128,000). vibration problem. Ten additional inserts were added to the face mill, thereby permitting an increase in feedrate. The shaft machining is performed on a purpose-built mach- ining center. First, there are two cuts taken on the forged blank. The operation is performed at 280 m/min with a 0.2 mm/rev feed. The cuts are made to approximately 3.5 mm. Then, there is a return to center line, and a short index in the Z-axis permits turning the chamfer. The double-sided inserts (eight cutting edges) are Sandvik 345R-1305M in grade GC4240. The inserts have an 0.8- mm radius and a 19° rake angle; it is capable of cuts up to 6 mm deep. The insert features a tough coated-carbide substrate to handle steel milling. The chamfering insert is a Sandvik TCMT in GC4225. Based on the combination of geometry and material, it can achieve depths of cut of as much as 4.8 mm. So what was achieved at Getrag Ford? The total cycle time is now 8 seconds. It had been 21 seconds. This is because of the elimination of a toolchange (remember: it is being done with a single tool, not two) and because the p The combined tool for transmission shaft machining developed by Sandvik for Getrag Ford Transmission. Instead of milling in one operation, and chamfering in another, the single tool accomplished both for a productivity increase.
