Abstract

This is a case study on determining the specification tolerances of the shiftability parameters of a gear box of a well-known brand of passenger car. The company was experiencing difficulty in setting up the specification tolerance, resulting in problems during the manufacturing process. The shiftability parameters Yi's are related to the dimensions of ni components 1, 2 , , . X X Xni The experimental design technique of Taguchi as modified by D'Errico and Zanio (1988) was used to find the probability distribution of all the shiftability parameters Yi's. The tolerance limits ( , ) LYi UYi for the Yi's were calculated after having selected 99% probability levels. These tolerance were applied to the shiftability parameters and a few prototypes were manufactured. The results obtained on these prototypes were encouraging and, hence, subsequently they were used by the design department in the gear box assembly.
