Automatic assist in estimating the production capacity of final machining for cast iron machine parts

Abstract

The paper presents a new approach for production capacities balancing. It is dedicated to companies performing machining services on a variety of materials on a small scale. The method is to help balance the production capacity on the basis of a defined labor intensity structure taking into account the share of set-up times and the level of defectiveness. The designed numerical algorithms along with the user interface make it possible to characterize machine tools and orders in the production system and compare the production capabilities of the system with the demand. The paper presents the algorithm working pattern, mathematical formulae used and a sample source code. An example of a computer application allowing to estimate the production capacity for sample orders (cast iron castings) and process routes in a selected cast iron production plant are also presented.
