The software uses advanced CAD tools to create a mathematical model of the assembly, taking into account all the relevant dimensions and tolerances of the individual parts. Tolerance stacking, often referred to as “stack-up analysis,” is a method used in engineering and manufacturing to assess the cumulative effects of variation in dimensions, tolerances, and specifications in a product’s design and manufacturing process. It then discusses considering the manufacturing Tolerances can be essential to ensuring that products assemble correctly, operate safely, and are profitable to manufacture. Such an analysis assumes that all dimensions in the tolerance chain have worst-case deviations from their nominal values. In such times, tolerance stack-up analysis should be able to cater to the need of achieving accuracy at a minimal cost.
