[0017] Specific implementation method
[0018] After analyzing the structural features of many products, the processing method of the present invention has typical application effects on the following two part structures.
[0019] The first type of typical deep groove cavity structure: relative to the corner size, the groove cavity depth is large. When this structure is used for tool selection processing according to the traditional processing method, the tool length-to-diameter ratio reaches or even exceeds 3 to 4, which is far greater than the general processing state. At this time, the sharp decrease in tool rigidity leads to a greatly reduced processing efficiency. After adopting the processing method of the present invention, the slot cavity is milled with a large-diameter tool (the tool radius is 4 times the corner radius), which can greatly reduce the tool length-diameter ratio and realize high-efficiency and fast cutting; using a small-diameter tool for corner plunge milli...
