Medium Density Fiberboard (MDF) is a type of hardboard which is made from wood fibers glued under heat and pressure. MDF are appropriate for the many exterior or interior industrial applications. Drilling is one of the most common and fundamental machining processes. It is most frequently performed in material removal and is used as a preliminary step for many operations, such as reaming, tapping and boring. Because of their importance in nearly all production operations, twist drills have been the subject of numerous investigations. This article aims to study the effects of the drilling parameters such as spindle speed, feed rate, and drill diameter (input parameters) used on the prediction of surface roughness (output response) on drilling MDF composite. The experiment was carried out by varying the drilling parameters and the output response surface roughness is modelled mathematically. The adequacy of the mathematical model is analyzed statistically using Analysis Of Variance (ANOVA) which gives a high degree of correlation between the input parameters and output response. It is evident that feed rate during drilling is the most influencing factor to surface roughness.Keywords

This article solves the customer complaint of poor performance of brake in certain tractors. This failure was reported particularly in Tractor which is predominantly used for puddling application. After prolonged usage, breakage was occurring in certain area of the actuating link. In order to overcome this problem, analysis has been carried out by using finite element method along with optimization technique. To obtain the best result various link designs have been created in CATIA and optimized with an optimization tool called OptiStruct solver in Hypermesh. The stress and deflection plots of existing and modified link were compared. Then the fatigue life of the optimized model is obtained from Nastran in order to know the life of the actuating link. In the same way fatigue life of the existing and modified link were analyzed and discussed.Keywords
