But how well does it bridge design and manufacturing ?Most manufacturing engineers would agree that, if ten different planners were asked to develop a process plan for the same part, they would probably e up with ten different plans. Obviously, and, in fact, there is no guarantee that any one of them will constitute the optimum method for manufacturing the part.What may be even more disturbing is that a process plan developed for a part during a current manufacturing program may be quote different form the plan developed for the same or similar part during a previous manufacturing program and it may never be used again for the same or similar part. That represents a lot of wasted effort and produces a great many inconsistencies in routing, tooling, labor requirements, costing, and possibly even purchase requirements. Of course, process plans should not necessarily remain static. As lot sizes change and new technology, equipment, and processes bee available, the most effective w
