摘要
为了研究CO冷却对Ti(C,N)基金属陶瓷切削性能的影响。本文设计了Ti(C,N)基金属陶瓷CO冷却气压0、1.5、2.5、3.5、4.5 kPa五种工况,对Ti(C,N)基金属陶瓷刀片进行切削测试,对比不同工况下Ti(C,N)基金属陶瓷轴向应力、表面粗糙度以及磨损量。实验结果表明:与真空冷却相比,CO冷却下Ti(C,N)基金属陶瓷轴向应力更大、表面粗糙度更小,刀具后刀面的磨损量更小,Ti(C,N)基金属陶瓷的切削性能更强。证明本文方法CO冷却对Ti(C,N)基金属陶瓷切削性能具有重要影响,当CO冷却气压在2.5 kPa~3.5 kPa区间时,Ti(C,N)基金属陶瓷的轴向应力最强、表面粗糙度最小,刀具后刀面的磨损量最小,金属陶瓷的切削性能最佳。在实际Ti(C,N)基金属陶瓷中CO冷却过程中将CO气压控制在2.5 kPa~3.5 kPa,以此保证Ti(C,N)基金属陶瓷具有良好的切削性能。
In order to study the effect of CO cooling on the cutting properties of Ti(C,N)⁃based metal ceramics,in this paper,five working conditions of Ti(C,N)⁃based metal ceramic CO cooling pressure 0 kPa,15 kPa,25 kPa,35 kPa,45 kPa were designed,and the Ti(C,N)⁃based metal ceramic blade was tested to compare the axial stress,surface roughness and wear amount of Ti(C,N)⁃based metal ceramic under different working conditions.The experimental results show that,compared with vacuum cooling,under CO cooling,the axial stress of Ti(C,N)⁃based metal ceramics is greater and the surface roughness is smaller,the wear on the flank face of the tool is smaller,and Ti(C,N)⁃based metal ceramics have stronger cutting performance.In this paper,the method of CO cooling has an important impact on the cutting performance of Ti(C,N)⁃based metal ceramics.When the CO cooling pressure is in the 25 kPa~35 kPa range,Ti(C,N)⁃based metal ceramics has the strongest axial stress,the least surface roughness,the wear on the flank face of the tool is the minimum,and the cutting performance of metal ceramics is the best.CO pressure is controlled at 25 kPa-35 kPa in actual Ti(C,N)⁃based metal ceramics to ensure good cutting performance of Ti(C,N)⁃based metal ceramics.
