This paper describes a technique for selecting and financially appraising CNC machine tools. The technique has been extensively used within a company operating a small-batch multi-product, manufacturing system. The paper describes how computer-assisted modelling was developed to identify key machined components from a sales forecast for a defined product mix. Data from key machined components was used to formulate the machine specifications for new CNC machines. These were then matched to the specifications of a number of commercially available machines. Having identified the optimum component range, further models were developed to assist the financial appraisal of specific machine tool investments and to identify optimum batch sizes. The models were also used to demonstrate the relationship between unit cost, production methods and batch size. Finally, the simulation routines available are discussed in order to illustrate the situations that can be evaluated.
