Create the Quality chains required for the specific assembly which will guarantee the workability of the design; Short Quality chains can be graphically represented on the assembly drawing, but the long Quality chains, where the graphical representation will be difficult, should be described as shown below:
2.Select a method of ensuring the quality of the functional parameters and calculate the Quality chains using methods of full interchangeability, partial interchangeability, group interchangeability and compensation method. If needed justify the use of the method of compensation and calculate the compensator(s). The aim is to assign the biggest possible tolerances and guaranteeing the workability of the design. This is directly linked to the sustainability of the new product!
