(1) for different materials, high-speed cutting mold technology test In reference to foreign high-speed milling parts of the process parameters found that foreign companies produce tools based on imported materials to do the test, with its recommended parameters in the high-speed processing of domestic materials mold When the effect is more obvious difference. Therefore, the use of foreign tools, in addition to the need to refer to manufacturers to provide the parameters, the actual process test is also necessary. Domestic tool manufacturers rarely recommend high-speed milling of technical parameters, so the choice of domestic tools more necessary to do the test, in order to obtain more satisfactory process parameters. The best choice of fixed manufacturers of tools, through the test, the formation of processing technology standards, and on this basis to optimize a set of suitable for the enterprise processing technology parameters, and into the enterprise standards. (2) high-speed cutting of the tool path and programming high-speed cutting tool technology in the tool path, feed mode and feed is the main content. Many toolpaths in high-speed cutting tool technology are designed to reduce tool wear and extend tool life, so the tool's path in high-speed cutting feed is much more complex than normal machining.
