Product Development Technologies (PDT) (Lincolnshire, Illinois is located in the U.S.) is a company engaged in, including tool design and manufacture of new product development, including transnational corporations. The company has been working to shorten the processing cycle and reduce production costs, advanced processing strategy for the exploration and research. PDT, when the company since its establishment, that is to carry out the surface coated with TiAlN Coating Clamping milling (using a square with a step structure APKT blade) in the high feed mold under the conditions of innovative technology research. From August 2004 onwards, with the LMT-Fette America (located in Cleveland, Ohio) to develop a high grade feed for the TwincutVario Clamping milling (using a new type of LC280TT blades), and had to applied to high-performance mold process studied. Experimental study in the final process, the use of the new design, manufacture and conducted a number of improvements Vario cutter and the resulting summed up the split crumbs processing patented technology, the exhaust of a model car to take over the base of the shell core box mold machining . The base dimension of 914 × 711 × 127mm, workpiece material is 4140 steel (30HRC). Processing in power 25hp, equipped with 50 horizontal machining center spindle MakinoMCB1210 on. Machining tool with 178mm overhang elongation. Processing test results are exciting, in ensuring the processing components required to achieve high precision at the same time, achieving significant economic results, machine tool processing costs by 12 U.S. dollars per cubic inch down to 6 U.S. dollars, the tool costs by 31 U.S. dollars per cubic inch down to 2 U.S. dollars, the total production cost from 42 U.S. dollars per cubic inch down to 8 U.S. dollars, spare parts production cost savings of more than 81.6% of the original process.
