However, it is difficult to computerise the conventional method for tolerance
stack up. So, this method is not useful for large assemblies where as graphical approach techniques provide an opportunity to handle large assemblies by writing a computer program.
Stack Up provides a centrally located multifunctional space which frees up floor space in living areas and can be used flexibly.
In the manufacturing engineering world, these deviations in machining linear dimensions are referred to as tolerance conflicts or "
stack ups," explains Lee Wagstaff, plant manager of Equitable Engineering Co, Troy, MI.
