Analysis of computer-aided manufacturing systems

BACKGROUND: Process of design and development of a controlling program starts after the conclusion of the previous stage of the product life cycle and it begins with the work of an engineering center. At this stage, development of new design solutions takes place and technical requirements specification for the developed product is approved with the customer.

AIM: Process of design and development of a controlling program starting after the conclusion of the previous stage of the product life cycle and beginning with the work of an engineering center.

METHODS: Based on that, the drawing of the product including technical requirements is prepared. Then, generally, this drawing is handed over to the department of process engineers-programmers where the design and development of the process control for the product takes place. As a rule of thumb, at this stage, a process engineer seeks advice from a drawing developer to obtain a full information about the product in order to eliminate any mistakes. There are possible cases where at this moment the drawing is given back to the engineering department due to impossibility of product manufacturing caused by lack of manufacturing abilities or poor design solutions making describing of manufacturing technology impossible.

RESULTS: The study result is the fact that the next stage that follows obtaining the technical requirements specification is development of technological process. The technological process should be formulated properly in terms of technology in accordance with internal enterprise standards (each enterprise can have own standards but the formulation structure is unite) and be sufficiently informative for the sake of exclusion of high chances of rejects during manufacturing. As the statistics shows, many enterprises suffer from high reject rate caused by improper behavior of CNC operators because of disappointments to the technological process.

CONCLUSIONS: Based on results of metalworking simulation, the method aimed to optimization of the strategy of machining high-speed metalworking at development of a controlling program has been formulated.
