Numerical control (NC) machines are a limited resource; therefore, they have created a bottleneck that has affected schedules. Many firms off-load as many tools to NC machine houses as possible to relieve the bottleneck. While this has relieved some of the congestion at the NC machines, it does not solve the problem. Another solution is selective programming, which allows the NC machine to produce more tools by machining less of a tool. The first step in the process of selective programming requires that each job be analyzed subsequent to the completion of the tool design and before programmming the tool. The analysis will determine areas that can be machined conventionally even if it is less efficient to do so. About 50% of NC machine work could be done on conventional machines, which are an abundant resource compared to NC machines. It is shown how, by using both NC machining and conventional machining, a product can be produced for the same cost, ahead of schedule.
