Classical versus numerical control machines in discrete material flow simulation based manufacturing architectures optimization

The research results presented in our paper are based on reports provided by different simulation models, using Witness software for a production cycle of a main shaft from a milling machine in order to determine the best manufacturing architecture based on improved productivity. The main purpose is to find out the number of machines necessary in order to obtain good production rates. We will also compare the productivity that will result from manufacturing the shaft when using classical machines, such as debtor machine, lathe machine, milling machine, boring and grinding machine with the one obtained when manufacturing the shaft on numerical control machines.
