Some Results on the Factor of the Surface Details When Turning C40 Steel Current
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 3
Abstract
This article presents some results of surface hardening (HV) experiment on machining C40 steel on CNC lathe. The experiment was conducted to investigate the effect of cutting mode (cutting volume - S, cutting speed - V and cutting depth - t) according to the experimental design of the center of rotation with 20 experimental points, and then identifying surface hardness for each sample. The experimental data help build the interaction graph of each pair of cutting conditions to the surface hardness. The data are also used to build the regression coefficient showing the relation between the surface hardness and the parameters of the cutting mode . The results show that all parameters S, V, t have a significant influence on HV. Specifically the cut depth t has the greatest influence on HV, followed by the influence of V and S; The interaction effect of the parameter of cutting mode on HV is quite complex. When increasing the value of S, V, t parameters, the interaction between them may increase or decrease HV.
