Why outsource your stack up analysis to spires Engineering Consultancy?

During your Engineering Peaks, Spires is able to assist your team in ensuring parts are fitted together by carrying out a tolerance stack-up analysis. We are your extended arm in assisting you to meet your objectives within a very competitive aerospace sector!

Product manufacturers utilize an organized flow of information to translate customer requirements into product requirements.

Tolerance Stack-Ups are vital to address mechanical fit and mechanical performance requirements. The mechanical fit is simply answering the question, “Do the parts that make up the assembly always go together?” Mechanical performance requirements would include the performance of mechanisms, like switches, latches, actuators, and the like. Other performance requirements could include optical alignments or motor efficiency. So what is a “stack-up”?

Tolerance stack-up calculations represent the cumulative effect of part tolerance with respect to an assembly requirement. The idea of tolerances “stacking up” would refer to adding tolerances to find total part tolerance, then comparing that to the available gap or performance limits in order.
