Abstract: Process planning is a key function of manufacturing companies that is responsible for the determination of methods by which a product is to be manufactured economically and competitively. To efficiently perform this function, computer-aided process planning (CAPP) systems are widely used. On the other hand, scheduling is another important function of manufacturing companies that gives the time each manufacturing operation should start and finish on assigned machine for the due dates of manufactured products to be efficiently met. Many computer-aided scheduling (CAS) systems are being used for the optimization of scheduling function. Unfortunately, because a poor collaboration or integration of CAPP and CAS systems, scheduling problems may occur in overloaded shops or high production costs may be obtained even for optimized process plans. The CAPP-CAS software that will be discussed during the lecture is a solution to overcome process planning and scheduling collaboration problems at make-to-order manufacturing of machined parts. There will be described the working sessions with the software, in terms of inputted data and outputted results. Some concluding remarks will be made on the quality of planning and scheduling solutions delivered by the software and on its future development.
