If friction is considered, fewer contacts can be used, so long as the applied cut-ting forces are not excessive. The choice of these datum points is often left up to thefixture designer. However, workpieces used in demanding applications can havetheir datums explicitly stated in the part drawing. Th[r]

The book and its related lectures are deliberately a survey of each manufac-turing topic and also focus on issues in today's business environment. This has twoobvious limitations:40610.2 Management of Technology407First, as far as depth is concerned, each of the chapters deals with technical materia[r]

The end mill canbe used to machine a feature such as a rectangular pocket with (ideally) verticalwalls.There are a very large number of different shapes of milling cutter for differentapplications. Single toothed cutters are possible,[r]
