PROJEKT TEHNOLOŠKOG PROCESA LEŽAJNE PRIRUBNICE

Zadatak završnog rada je projektiranje tehnološkog procesa ležajne prirubnice. Kroz rad su prikazani svi važni dijelovi tehnološkog procesa, započevši sa tehnološkom analizom izradka s tehnološkog i konstrukcijskog stajališta. Slijedom toga dolazimo do odabira sirovine, gdje sam se odlučio za otkivak s obzirom da u slučaju šipke, volumen strugotine bi bio preveliki, te bi rezultiralo povećanom potrošnjom alata i strojeva. Koncept tehnološkog procesa sam postavio vodeći se logikom da je cilj ovog rada prikazati znanje i razumijevanje kod studenta, stoga sam uzeo CNC strojeve zbog boljih uvjeta za rad, ali sam operacije odabrao na način kako bi se izvodile i na starijim izvedbama strojeva. Nakon toga sam pristupio detaljnoj razradi tehnološkog procesa, gdje sam izračunao sve potrebne parametre obrade, za svaki zahvat navedenih operacija. Slijedila je izrada tehnološke dokumentacije, koja služi radnicima u proizvodnji kako bi znali što trebaju raditi, bez posebne edukacije. Tu se vidi koliko je tehnolog važan za postrojenje, jer jedan čovjek odradi posao koji bi inače svaki radnik radio sam za sebe. Na kraju sam izračunao proizvodnu i ekonomsku brzinu rezanja za jedan zahvat grube i fine obrade. Izradom ovog završnog rada sam stekao mnogo praktičnog znanja koja će mi sigurno biti od velike pomoći na budućem poslu. Planiranje i utjecaj na kvalitetu rada koja se primjenjuje ovdje, može se primijeniti i na ostalim poslovima i strukama, što sam se mogao i sam uvjeriti radeći u struci i van struke. Projektiranje tehnoloških procesa zahtjeva puno vremena, i još više truda, ali na kraju se to svakako isplati. Zato mislim da je ovo jako zanimljivo radno mjesto i iznimno mi je drago što sam odabrao ovu temu za završni rad.The final task is to design technological process of the bearing flange. All the important parts of the technological process are presented through the work, starting with the technological analysis from the technological and constructive point of view. Consequently we come to the selection of raw materials, where I have decided to work with a forged steel, since in the case of a rod, the volume of the saw would be too large, which would result in increased consumption of tools and machines. The concept of the technological process has been set to show konwledge and understanding of a student as the main goal of this paper. Therefore I have chosen CNC machines because of the better working conditions, but I have chosen the operations which can also be performed on older machines. Afterwards, I approached the detailed elaboration of the technological process, where I calculated all the necessary processing parameters for each operation of all operations mentioned. It was followed by the production of technical documentation, which serves workers in production so they know what they need to do without special education. In that way we can see how important the process itself is because one man is doing a job that would otherwise be the work of every worker himself. At the end I calculated the production and economical cutting speed for one rough and fine processing operation. By completing this final work, I have gained a lot of practical knowledge that will surely be helpful for my future work. The planning and impact on the quality of work applied here can also be applied to other jobs and careers, which I have experienced myself by working in a gerat range of different professions. Designing technological processes requires a lot of time, and even more effort, but ultimately it's worth it. That is why I think this is a very interesting job and I am very glad to have chosen this topic for my final work
