Abstract Details

2003, MS, University of Cincinnati, Engineering : Industrial Engineering.
Tolerance control is critical in assuring product quality in discrete part manufacturing. This work deals with an important aspect of tolerance control, namely, the assignment of production tolerances and determination of mean working dimensions. The guiding principle is that the tolerance is used to account for the inevitable errors in manufacturing, which are collectively reflected in process capability. Therefore, a methodology based on process capability analysis is proposed to determine process tolerances for pre-finish machining operations. The mean working dimensions are determined by examining the inter-relationship between various tolerances to calculate the minimum material removal required for each machining operation. The methodology is based on the use of existing production equipment where historical data is available. An analytical method of estimating process capability based on tolerance normalization is proposed and the results are validated using Monte Carlo Simulation. Algorithms are developed and their use illustrated using several simplified actual parts. This work is a step towards developing a scientific method of solving the tolerance assignment problem based on rigorous analysis of manufacturing errors. This will not only eliminate the trial and error process usually involved in a tolerance allocation process but also result in the realistic tolerances possible to achieve using existing equipment.
