| Stainless steel material is widely used in various industrial fields for its excellent synthetic property. Stainless Steel is a ductile material, and it is not to broken chip in machining. The domestic manufacturers to produce tools for the processing of stainless steel cutting blade is not effective in chip breaking, its life is short. Its market is largely occupied by foreign tools. Therefore, it is significant to research the positive inserts'grooves for stainless steel machining and so we can know about the broken mechanism of broken grooves, quicken the process of developing broken grooves for hard machining material, improve our self-independent developing ability.The paper systematically summarizes the background and tendency of the development of chip control and the design of Cemented Carbide Indexable Inserts chip-breaking groove that developed in homeland and foreign countries; through the analysis of the two kinds of advanced foreign chip-breaking grooves and abundant experiments, and compared these typical chip breaking groove of the properties and wear resistance. According to the results, We can conclude:blade width, rake angle, edge angle play a key role in the groove parameters.Based on the mentioned theory and experiment, the chip-breaking groove design is proposed, two sorts of grooves cutting tools contained more than fifty standards in the M series are developed, and these tools are applied in Stainless steel machining. The development of stainless steel positive inserts is compared with similar foreign inserts cutting test. The results showed that:The cutting process is more stable and faster, and the chips could be removal out fluently. In general, its cutting performance has achieved the same level as the foreign advanced cutting tool. Those designs have been transmuted into finished products that have been sold to domestic and foreign markets, and achieved perfect technologic and economic benefits. |
