在干切削状态下,通过改变切削参数,研究了用高速钢刀具高速铣削树脂砂铸型时刀具的磨损行为,分析了刀具的磨损形态和砂型切削机理。结果表明,后刀面磨损是树脂砂铸型铣削过程中刀具的主要磨损形式,不同切削参数对刀具磨损的影响程度不同。 Under the condition of dry cutting, the wear behavior of the tool when the resin sand mold is cut by high speed steel cutter is studied by changing the cutting parameters. The wear pattern of the tool and the cutting mechanism are analyzed. The results show that the flank wear is the main form of tool wear during resin milling, and the influence of different cutting parameters on tool wear is different.
