The aim behind applying functional tolerancing to a mechanism is to widen the tolerances
used in parts manufacturing according to the effective functional properties of the product.
This step may be performed using CAD systems and geometrical specifications defined by
ISO standards. The present paper will describe the complete process involved in functional
tolerancing. The CLIC tolerancing method has been implemented within an Excel software
environment. CAD models for parts have been imported via a STEP interface. According to …
