Today tooling-related technologies are treated extremely seriously as it is here that optimum production output consistency of machined product and value-added activities are realised. Often companies feel that to increase productivity - to offset the high capital investment in the plant and to amortise such costs . pay-back is the most advantageous way forward. This strategy can create bottlenecks and disrupt the harmonious flow of production at later stages within the manufacturing environment. Another approach might be to maximise the number of components per hour or alternatively drive down costs at the expense of shorter tool life which would increase the non-productive idle time for the production set-up. Here the prime1 tooling factor should not be for just a marginal increase in productivity and efficiency nor the perfection of any particular operation. If bottlenecks in component production occur they can readily be established by piles of machined parts sitting on the shop floor awaiting further valued-added activities to be undertaken. These line-balance production problems need to be addressed by achieving improved productivity across the whole operation perhaps by the introduction of a Taguchi-type component flow analysis system within the manufacturing facility. The well-known phrase that No machine is an island . for part production and that manufacturing should be thought of as One big harmonious machine and not a lot of independent problems will create a means by which .
