Realizing the nature of the manufacturing process used to make a part can help determine the locations and the optimum number of inspection points. Face and End milling processes are used in this work to produce plates and sheets. A Finite Element Analysis (FEA) model has been developed for cutting of flat plates. That model helps minimizing the number of inspection points. That model suggests that maximum error is in the regions near the center of the plates and sheets. Experiments have been conducted to verify the model. Four pieces of flat plates and two sheets have been made then inspected using coordinate measuring machine (CMM). The experiments showed that the reduction in number of inspection point, in face milled flat plates, reached to about 95.5% compared to the number of population points with a difference in tolerance of about 2.8%. Also, the results showed that the reduction in the number of points, in end milled sheets, reached to 95.6% with a percentage difference in the tolerance of about 7.1%.
