Abstract

Tolerance analysis is used for an optimal tolerance assignment to satisfy the function requirements, and mean while minimizes production cost. This paper introduces a computerized procedure for optimal tolerance assignment in mechanical assemblies to satisfy the function dimensions. The developed computer system has the ability to integrate CAD systems which support DXF (Drawing Interchange File). For example, the software receives a DXF file of an assembly then analyzes it to detect the individual parts of the assembly using rules of form definitions in system knowledge base. Also, the developed system estimates the dimensions and the type of chain link for each part to generate the Tolerance chain link relation. The optimization problem is formulated automatically with tolerance-cost functions as an objective function to be minimized. The constrains are the limits of function dimensions and process capability boundaries. Then, the program generates M. file which used by MATLAB package to calculate the optimal tolerance values. A mechanical assembley case study is used as an applicaron to show the capability of the new system
