Drilling technology and experimental research of ultra-high strength steel A100

In order to study the influence of different drilling parameters on the cutting force during the drilling process of A100 ultra high strength steel, the simulation analysis and drilling test of A100 high strength steel were carried out by single factor test method. Firstly, the dynamic simulation software AdvantEdge cutting simulation software is used to build the A100 steel drilling model, and the cutting force of the A100 steel under different drilling parameters is simulated and analyzed. Secondly, the cutting force is measured in the process of drilling A100 steel by three direction dynamometer and the cutting force is analyzed, and the simulation results are compared with the test results. The results show that the size of drilling force decreases with the increase of spindle speed, and increases obviously with the increase of feed rate, while drilling step depth and feed are the main factors affecting the drilling. Therefore, in the drilling of A100 steel, higher spindle speed, smaller feed and moderate drilling step depth should be selected. (paper)
