Do modelowania etapów projektowania technologicznego obróbki użyto notacji BPMN. Opisano trzy podejścia metodyczne komputerowego wspomagania projektowania technologicznego obróbki CAPP. Następnie omówiono model współbieżnego projektowania konstrukcyjno-technologicznego wspomaganego systemami CAPP i CAAPP oraz DFM i DFA. W pracy zaproponowano dwie koncepcje procedury przygotowania wyceny wspomagane systemami CAPP.

For modeling of stages of machining process planning was used Business Process Modelling Notation (BPMN). Three methodological approaches of computer aided process planning (CAPP) were described. Then a model of concurrent preparation of construction and technology aided by systems CAPP, CAAPP, DFM and DFA was discussed. The paper proposes two concepts of procedures for the preparation of valuation aided by CAPP systems.

Approach for the development of heuristic process planning tool for sequencing NC machining operations

This chapter deals with the process planning for sequencing NC (numerical control) machining operations. This task of selecting and ordering of machining operations is still done manually in principle. In order to overcome this problem, an approach for enabling the automatic preparation of work plans with methods known from the graph theory is introduced in this chapter. Therefore a work plan is mapped into a directed graph in a mathematically defined way. Based on that, it is possible to use algorithms to find the shortest path and a Hamiltonian path inside this directed graph as optimal sequenced solution under given requirements. Thus, the work plan is structured and re-ordered. Finally the corresponding NC machining code will be generated and distributed to the machinery.
