| Abstract [eng] |
Manual labour becoming a luxury and industrial automation becoming more and more popular, computer aided process planning (CAPP) has become a must in today’s manufacturing companies. In this work CAPP systems and their applications in Lithuanian manufacturing enterprises were analysed. The aim was to analyse main types of computer aided process planning systems and choose the one that fits Lithuanian manufacturing companies. During the analysis, it was noticed that no new of the mentioned system were developed for 20 years. A question arose – why did this happen as the need for this kind of systems has remained and even kept growing. While analysing literature sources and systems it was found that CAPP system being a bridge between CAD and CAM systems, it was merged with the mentioned CAD system. To compare old and new type systems, 2 different systems were analysed: stand-alone variant CAPP system (CAME SAT) and integrated generative process planning system, merged with CAD software (SolidWorks). With the help of three prepared test tasks systems functionality, ease of use, reliability and viability was analysed and compared. To find out which system best meets todays manufacturing requirements, the results and applications of both systems were analysed and compared. The situation of Lithuanian manufacturing enterprises was also analysed to see their automation level and the need for computer aided process planning systems. |
