Abstract


In industrial practice, there are situations in which it is necessary to select a technology from several manufacturing technologies for a product. One of the methods that can be used in this regard is the analytic hierarchy process method. Using the method involves identifying and weighing some selection criteria. Subsequently, the composite weights of each of the technologies taken into account are determined based on each of the identified criteria. The method was applied to select a technology for separating samples from a workpiece in the form of a plate. It was considered that the separation can be achieved by classical technologies and, respectively, by some non-conventional technologies, such as wire electrical discharge machining, laser beam machining, and plasma beam machining. For the conditions considered, it was found that the most convenient technology is the one based on the use of a plasma beam.
