COC Tooling and Stamping Halves Press Tool Times PowerINSPECT On-Machine Verification system allows the leading press tool manufacturer in Taiwan, COC Tooling and Stamping, to halve the time needed to manufacture its tools.
This new technology, Delcam’s PowerINSPECT On-Machine Verification
system (OMV), has helped the COC Tooling and Stamping (COC) gain the maximum
benefit from its recent investment in high-accuracy, high-speed machining
equipment. Company President, Mr. Y.K. Tseng, explained that the introduction of PowerINSPECT OMV had produced enormous increases in productivity, even though it had only been in use for six months. "With OMV, we can measure the press tools on the machine and find out if there are any problems immediately,” he claimed. "We can obtain a direct comparison with the CAD model, which is much more reliable than using inspection methods based on drawings.”
Most of the machine tools at COC are between four and five meters in length, and many of the press tools being manufactured are of similar size. "Moving parts of that weight and size to the CMM for inspection used to be extremely difficult and slowed down the whole production process,” said Mr. Tseng. The main problem with these large tools is that the longer cutters needed to machine to their full depth can be pushed out of alignment, especially near the bottom of the part. This gives an oversize surface on the punch, while the cavity will be undersize. "Previously, because of the problems in setting up the tool back on the machine, we would use hand finishing to correct any errors,” remembered Mr. Tseng. "This wasn’t very accurate and was also very time-consuming. Now, we can re-machine the surface on the machine tool, which is both faster and more reliable.” This higher quality tooling can be seen in the much reduced try-out times needed for new tools. "We can now be confident that the tool will work as soon as it comes of the machine,” claimed Mr. Tseng. Prior to the introduction of PowerINSPECT OMV, COC had been a Delcam customer for several years, using the PowerMILL CAM system for all its 3D machining. "We introduced our first PowerMILL seat around three years ago,” said Mr. Tseng. "Our operators found it easier to use and we could obtain a much better surface finish so we decided to standardise on the Delcam software. We have seen even more improvements following the introduction of our new 15,000 rpm spindle machines.” See all the Press Releases from Delcam sites - Click Here Read a recent press release about - Got a Cool Job in Tooling?- Get the word out today!
