Selective AssemblyThe selective assembly can be referred to as a concept where the subcomponents are assembled to form a proper final assembly which will in return provide the highest tolerance specification.Using selective assembly when the parts are being manufactured, the selective assembly resembles an old concept of inspection, in which the component is being identified as good or bad. If all the parts are correct and the component is good then it will be used for assembly or else it will be used for scrap purposes.In selective assembly, if the components are divided into different categories, then the groups will ...

The guidelines for designing a gauge should be carefully done. The form of go gauges should exactly combine with each other so that the mating parts can fit into each other properly. These gauges, especially the go gauges should enable simultaneous checking of several dimensions and must be used for the maximum amount of time. Then the no gauges should be able to check the number of dimensions at any time. It must be taken care of and given the maximum amount of possibility.Material for GuagesThe materials to be considered for gauges should have good properties. The material used for ... Read More
