【正文】 New tools maximize new machine designs The primary tooling concerns when machining aluminum are: minimizing the tendency of aluminum to stick to the tool cutting edges。 ensuring there is good chip evacuation form the cutting edge。 and ensuring the core strength of the tools is sufficient to withstand the cutting forces without breaking. Technological developments such as the Makino MAGSeries machines have made tooling vendors rethink the any stateoftheart machine technology. It is vital to apply the right tooling and programming concepts. Materials coatings and geometry are the three elements in tool design that interrelate to minimize these concerns. If these three elements do not work together, successful highspeed milling is not possible. It is imperative to understand all three of these elements in order to be successful in the highspeed machining of aluminum. Minimize BuiltUp Edge When machining aluminum, one of the major failure modes of cutting tools the material being machined adheres to the tool cutting edge. This condition rapidly degrades the cutting ability of the tool. The builtup edge that is generated by the adhering aluminum dulls the tool so it can no longer cut through the material. Tool material selection and tool coating selection are the two primary techniques used by tool designers to reduce occurrence of the builtup edge. The submicron grain carbide material requires a high cobalt concentration to achieve the fine grain structure and the material’s strength properties. Cobalt reacts with aluminum at elevated temperatures, which causes the aluminum to chemically bond to the exposed cobalt of the tool material. Once the aluminum starts to adhere to the tool, it quickly forms a
