Conceptual Design of Manufacturing System

U ovom diplomskom radu prikazan je idejni projekt proizvodnog sustava strojne obrade za šest proizvoda. Prikazana je analiza tehnoloških i proizvodnih karakteristika svakog proizvoda. Na početku rada prvo su definirane količine koje će se proizvoditi u toku jedne godine za svih šest proizvoda. Zatim su opisani i analizirani svi proizvodi sa konstrukcijskog, proizvodnog i tehnološkog stajališta. Sljedeće poglavlje prikazuje detaljan plan obrade svakog proizvoda te prikazuje vrijeme trajanja svih operacija na pojedinim strojevima, što CNC što univerzalnim koji su detaljno opisani, njihova nabavna vrijednost,specifikacije itd. Na temelju vremena obrade napravljene su matrice pomoću kojih smo izvršili grupiranje proizvoda, u ovom slučaju skraćenom procesnom metodom te smo dobili odgovarajuće modele proizvodnog sustava prema odgovarajućem stupnju iskorištenja. Nakon grupiranja odredili smo odgovarajući prostorni raspored za svaki model te napravili hodogram obrade i odredili način transporta. Napravljen je proračun za minimalan broj radnika u sustavu te je definirano terminsko opterećenje. Na kraju su napravljeni ciklusi izrade za pojedini proizvodni model.In this graduate thesis there is presented the conceptual design of the machining system for six different workpieces. An analysis of the technological and production characteristics of each workpiece is presented. . At the beginnig of the thesis are defined quantities that will be produced during one year for all six workpieces. Then, all products from the construction, production and technological point of view are described and analyzed. The next chapter shows a detailed processing plan for each workpiece and shows the duration of all operations on individual machines, both CNC and universal, which are described in detail ( their purchase value, specifications, etc.) . Based on the processing time, the matrices are formed by means of which grouping of the workpieces is done, in this case by an abbreviated process method, and we obtained the appropriate models of the production system considering degrees of utilization. After grouping, we determined the appropriate spatial arrangement for each model, defined workflow of processing and transport system. A calculation was made for the minimum number of workers in the system and the term load was defined. In the end, production cycles were made for each production model
