What is the difference between statistical and conventional tolerancing methods?
What will be an ideal response?
Statistical tolerancing is a way to assign tolerances based on sound statistical practices rather than conventional tolerancing practices. It can be applied only when appropriate statistical process control methods are used for manufacturing. When conventional tolerancing methods are used, often the total assembly tolerance is divided by the number of individual parts in the assembly. A portion of this assembly tolerance is then assigned to each component. The problem with this method is that it usually results in tolerance values being more restrictive than necessary. When manufacturing processes are monitored by statistical process controls, technicians and engineers are better informed about processes for which tolerance values can be increased to reduce manufacturing costs.
