| Popis: | In the market for cutting tools there are not specific tools for machining polymers, where the main difficulty is chip control. Cutting tools are only available for machining metals. In this study, tests were performed turning nylon, with the use of standard carbide tools, in order to identify tool geometries and cutting parameters able to perform the machining of the material, controlling the chip in the best way possible. The comparison criterion used was the chips formation, since usually for nylon, occurs on continuous tape. The tools that have the best results were the TNMG 160408-PF, used for machining steel with the following cutting parameters: cutting speed of 450 m/min, depth of cut of 2.0 mm and advancement of 0.35 mm/rev; whose chip formed long tubular long tangle, and the tool CCGT-120408 BAL, for the machining of aluminum, with the same depth and advancement parameters, but with cutting speeds of 600 m/min and 750 m/min, providing chip formation of fragmented |
