Abstract

Currently, the assembly tolerance allocation of precision mechanical equipment can be determined by many methods such as engineer’s experience, the worst on worst tolerance analysis method, the root sum square tolerance analysis method, or the Monte Carlo simulation method. However, there are other factors that need to be considered when engineers allocate individual tolerance values to each part. Examples of these factors include the production cost and the uncertainty of the measuring equipment. A new method for allocating a suitable tolerance value to each part or component was developed. By using a real industrial case study, the experimental results indicated that the new method could provide suitable component tolerance values for the production line. Compared with the leveling technique, the results also indicated that the new method can provide better tolerance values. However, this new method has a major limitation in that it can be used only for linear tolerance.
