Assembly Tolerance Analysis with Simulation and Optimization Techniques 870263

A computer simulation method of assembling parts of a mechanical assembly has been developed by Deere & Company to statistically analyze tolerance stack-up of complex two-dimensional and three-dimensional assemblies. It offers a way to predict the impact of design tolerance and manufacturing variation on assembly quality before prototype machine builds. This technique also provides assessment of design tolerance and manufacturing capability impact on current production assemblies. This method identifies both the amount of variation relative to specifications and the percent contribution of the major contributors to the variation.
