From Design to Inspection: The Use of GD&T for Predictable Assembly

Abstract

In the good old days one person thought it up, sketched it, made it, inspected it and assembled it; when it did not work, they sketched it again. In the better new days five people each do one of the five, which means the drawing has to carry the meaning on its own – and the cost and complexity of modern products mean the idea has to be shown worth building before it is released. That is the case Bill Tandler and Mark Denman make for geometric dimensioning and tolerancing, taken from design through to inspection with predictable assembly as the test of whether it worked.
