Digital vision system and mechanical design are areas that affect productivity. Good combination of digital vision system and mechanical design is required to obtain better vision image and accuracy. The better of the two combinations also helps operator to perform their job easier and faster and thus, increasing the productivity of the finish product. This research is to decide the most important combination of digital vision system and mechanical design in the setup of product gap inspection in a production line. The first step of the study was to determine the factors that influence the accuracy; in this case they were the accuracy of product gap measurement. The second step was to determine the level of each gap factor and then design for fractional factorial experiments. There are two factors being evaluated which have influence on the accuracy that is the digital vision camera resolution and increasing number of gaps of the product. There are forty six combinations of experimental runs to obtain the process capability index and the tolerance of the product. Minitab was used to identify the problem location. The result shows that the higher process capability index and lower tolerance of the product can be achieved by using the combination of servo motor system with digital camera system
