Abstract

An experimental study has been carried out to investigate and compare the cutting tool performances represented by insert wear, surface roughness and cutting forces of an uncoated carbide (H13A) and three coated carbides GC2015 ( TiCN / Al2O3 / TiN ), GC1015 (TiN) and GC4215 ( TiCN / Al2O3 ) during the dry turning of AISI4140 steel. Turning was carried out during 5 minutes on cylindrical specimens (80 mm diameter and 400 mm cutting length) along with a depth of 0.5 mm, a feed rate of 0.08 mm/rev, and with a cutting speed of 350 m/min. The wear results show the effectiveness of both GC2015 and GC4215 cutting inserts where the flank wear rate of the monolayer insert (GC1015) reaches approximately 2 times that of the bilayer insert (GC4215) and 4-times that of the multilayer insert (GC2015), while insert H13A demonstrated the highest wear. Moreover, SEM analysis shows that abrasion, adhesion and chipping are the dominant wear mechanisms. The surface quality obtained with the coated GC2015 insert is found to be 1.38, 1.63 and 4.63 times better than those obtained with GC4215, GC1015 and H13A inserts respectively. Finally, the coated GC2015 (CVD) cutting insert is identified as the leading material in terms of cutting force as the results found show that the ratios are ( Ft-GC4215 / Ft-GC2015 ) = 1.05, ( Ft-GC1015 / Ft-GC2015 ) = 1.13 and ( Ft-H13A / Ft-GC2015 ) = 1.77.

无涂层、PVD、CVD和MTCVD涂层硬质合金刀片干式车削AISI4140钢性能的比较研究

对AISI4140钢干车削过程中，未涂覆硬质合金(H13A)和涂覆硬质合金GC2015 (TiCN / Al2O3 / TiN)、GC1015 (TiN)和GC4215 (TiCN / Al2O3)的刀具切削性能进行了试验研究和比较。在5分钟内对圆柱形试样(直径为80 mm，切削长度为400 mm)进行车削，车削深度为0.5 mm，进给速度为0.08 mm/rev，切削速度为350 m/min。磨损结果表明，GC2015和GC4215切削齿都是有效的，其中单层齿(GC1015)的齿面磨损率约为双层齿(GC4215)的2倍，多层齿(GC2015)的4倍，而H13A齿的磨损率最高。此外，SEM分析表明，磨损、粘附和切屑是主要的磨损机制。GC2015涂层刀片的表面质量分别是GC4215、GC1015和H13A涂层刀片的1.38倍、1.63倍和4.63倍。最后，涂层GC2015 (CVD)切削齿在切削力方面的比值为(Ft-GC4215 / Ft-GC2015) = 1.05， (Ft-GC1015 / Ft-GC2015) = 1.13和(Ft-H13A / Ft-GC2015) = 1.77，从而确定了涂层GC2015 (CVD)切削齿为领先材料。
