Problems solved by technology
[0003] The main technical defects of the original technical solution are: First, the milling process of high-strength aluminum alloy and cast iron parts has long production cycle, low processing efficiency, unstable quality, and large tool loss, which affects the production of various types of engines. efficiency
Second, the spindle power utilization rate of CNC equipment is low, the overall level of CNC machining technology is extremely unbalanced, and the comprehensive effects and advantages of CNC machining technology are far from being brought into play
[0004] The main reason for this situation is the artificial formulation of CNC cutting parameters and the lack of reasonable choices.
For high-speed machining, machining stability is a key factor in high-speed machining technology, and cutting parameters from traditional sources are difficult to fully meet the requirements of high-speed machining
