Piston pins play a crucial part for providing support to the connecting rod which plays a pivotal role in functioning of the automobile. The current work focusses on identifying the factors which affect the inner bore diameter for piston pins during the boring process and also finding an optimal setup which can reduce tool life. In order to identify the parameters which, have an effect, factors such as speed, feed and depth of cut were considered and a full factorial design of experiments were conducted with 3 replicates. The response variable used while conducting include mean inner diameter and range. The experiments were conducted using randomization principle and experimental conditions were run according to random number generator using Minitab software. Analysis of variance (ANOVA) was conducted using Minitab and based on the ANOVA results, main effects and interaction plot, optimal parameters values were chosen which would provide optimal inner bore diameters. In addition, optimal parameters where accordingly chosen which would provide longer tool life.
