机械零部件制造加工过程中,铝合金材料得到了广泛的使用。铝合金与大部分钢材和铸铁材料相比,具有一个明显的优点:较低的屈服强度。因此,加工中需要的切削力较低,可以在刀具不发生过量磨损的情况下提高切削速度和进料比。但是,就铝合金的切削性能而言,它的柔韧性会带来两个严重的问题:第一,容易出现粘结的现象。铝质颗粒粘结到切削刀具的表面,严重影响加工件表面粗 Mechanical parts manufacturing process, aluminum alloy materials have been widely used. Aluminum has the obvious advantage over most steel and cast iron materials: lower yield strength. As a result, the cutting forces required during machining are low, which increases the cutting speed and the feed ratio without excessive tool wear. However, the ductility of aluminum alloys poses two serious problems with regard to the machinability of aluminum alloys. First, there is a tendency for sticking. Aluminum particles bonded to the cutting tool surface, seriously affecting the rough surface of the workpiece
