Technological improvements in the manufacture of wedge brake for automatic transmission

Diplomsko delo obravnava tehnološke izboljšave mehanske obdelave z odrezovanjem na velikoserijskem artiklu zavorne zagozde. Uvodoma smo predstavili osnove CAD/CAM sistema in CNC-obdelovalne stroje, na katerih bomo izvedli obdelavo. Nadalje smo opisali karakteristike obdelovanca in potek proizvodnega procesa. Sledi predstavitev strojev in orodij, ki smo jih uporabili za izdelavo in kontrolo končnega izdelka. Temeljito smo razdelali posamezne delovne operacije in uporabljena orodja. Rezultat analize prikazuje kritične karakteristike, ki so bile predmet tehnoloških izboljšav. Pri tem smo se posluževali rezilnih orodij različnih proizvajalcev, ki smo jih testirali z različnimi obdelovalnimi režimi. Rezultat analize je časovna in stroškovno optimalna obdelava zavorne zagozde.My diploma thesis talks about the technological improvements in processing metal mechanically by cutting it off on a multiserial product of a brake wedge. In the introduction, the basis of CAD/CAM systemand CNC-processing machinery are introduced. There will be processing done on them. Furthermore, the characteristics of the processed product and the course of the production process are described. Then, there are machinery and tools introduced. They have been used for the production and the control of the final product. Certain working operations and tools used have been described into details. The analysis result shows serious characteritics which have been the subject of the technological improvements. Here we have used cutting tools of different producers which have been tested by different processing procedures. The result of analysis is a brake wedge for which optimal costs and time have been spent
