Tolerance is designed to ensure an integrated product design phase the functional requirements of the parts at the same time choose a suitable tolerance. It is the establishment of tolerance from the perspective of an integrated mathematical equation using Monte Carlo simulation approach to a comprehensive simulation study of tolerance. Based on the characteristics of the cumulative change in the model based on integrated simulation of the tolerance equation, using Monte Carlo simulation method. Samples obtained through the simulation of the equation, then the use of origin to deal with statistical analysis software, the results reflect the characteristics of degrees of freedom within the tolerance zone changes in the design stages of guiding significance for tolerance allocation.
