“…According to a study that comprehensively considered tool performance and price factors, cemented carbide tools are most well-suited for cutting CGI [ 10 ]. With the aim of improving the tool lifespan, researchers optimized the machining CGI machining process, mainly by considering the material [ 11 , 12 , 13 , 14 ], tool angle [ 15 , 16 ], tool coating [ 17 , 18 ] and cooling lubrication condition [ 19 , 20 ].…”

Compacted graphite iron (CGI) has become the most ideal material for automotive engine manufacturing owing to its excellent mechanical properties. However, tools are severely worn during processing, considerably shortening their lifespan. In this study, we prepared a series of cemented carbide-coated tools and evaluated their coating properties in cutting tests. Among all tested coatings, PVD coating made of AlCrN (AC) presented with the best surface integrity and mechanical properties, achieving the best comprehensive performance in the coating test. The AC-coated tool also exhibited the best cutting performance at a low speed of 120 m/min, corresponding to a 60% longer cutting life and the lowest workpiece surface roughness relative to other coated tools. In the cutting test at a high speed of 350 m/min, the CVD double-layer coated tool (MT) with a TiCN inner layer of and an Al2O3 outer layer had a 70% longer cutting life and the lowest workpiece surface roughness relative to other coated tools.
