双金属零件在许多行业中用于减轻工件的重量和降低成本，在高负载和磨损下工作。这种复合材料的应用之一是汽车工业。在这项工作中，刀具磨损和切削力在端面铣削铝和铸铁制成的零件进行了研究。以发动机缸体常用材料A356和GG25铝合金为材料，分别加工铝合金和铸铁试样，实验加工长度为3.6m，采用图像处理方法（KNN方法）计算了刀具后刀面的刀具磨损量。结果表明，在所选择的加工参数下，铝合金试样的磨损不显著，而铸铁和铸铁材料的磨损则被考虑在内。试验还发现，铸铁件的磨损量和切削力均远高于铸铁件，且切削力与刀具磨损量之间存在相似性。由此可以得出结论，而不是耗时的磨损试验，刀具磨损趋势，在端面铣削的零件，可以预测从切削力测量。KNN图像处理方法对于计算刀具磨损量非常准确。
Bimetallic parts are used in many industries for weight and cost reduction of workpieces, working under high loads and wear. One of the application for this type of composite material is in automotive industry. In this work, the tool wear and cutting forces in the face milling of bimetallic parts made of aluminum and cast iron were investigated. A356 and GG25 alloys that are common materials for bimetallic engine cylinder block were selected as material for aluminum and cast iron samples, respectively. Machining length was 3.6 meters in the experiments and the tool wear was calculated on the flank face of tool using image processing method (KNN approach). Results indicated that with the machining parameters selected here, the wear of aluminum sample is not significant but the wear for cast iron and bimetallic materials was considered. It was also discovered that the wear and machining force for bimetallic parts are much higher than samples with cast iron material and the analogy was observed between cutting force and tool wear quantities. From this, it can be concluded that instead of time consuming wear tests, the tool wear trend in face milling of bimetallic parts can be predicted from cutting force measurements. It is also conculded that KNN image processing method is very accurate for calculating the tool wear.
