Statistical Prediction of the Two-Hole Two-Pin Locating Accuracy
Journal Title: RECENT - Year 2009, Vol 10, Issue 25
Abstract
The mechanical assembly method of two pieces having: one two parallel holes, the other two pins, is often used when have to achieve a high position and orientation accuracy. The prediction of the assembly accuracy is a one of the indispensable stages in design process. In this paper the geometrical tolerances are involved, the RFS tolerancing (the geometry tolerance is applied regardless of its feature size), a mathematical model of the geometric errors and the associate algorithm are proposed, the results of the Monte Carlo simulations are presented and analysed. The weights of the errors factors are analysed and based on its several design recommendations are indicated.
