Evaluation of Significance of Process Parameters by Statistical Method (Anova Tables) for Friction Surfaced Tool Steel M2 Deposit Over Low Carbon Steel

  • V.Pitchi Raju


This paper discusses the procedure for to test the significance of process parameters of physical characteristics such as width, height and surface roughness of the friction surfaced tool steel M2 deposit over low carbon steel. This  evaluation can be carried out by construction of ANOVA tables, Then write the regression equation after substitution of coefficient of significant factors and afterwards eliminating least important terms, the simplified regression equation can reveals the significance of process parameters corresponding to respective physical quantities of friction surfaced tool steel M2 deposit. These results show the variation of the physical quantities of the deposit corresponding increase or decrease of process parameters such as friction pressure, rotational speed and welding speed.
