GRAPHIC MODELING OF A DRILLING FIXTURE AS A PART OF EMCO MILL 55 CNC MILLING AND DRILLING SYSTEM

Abstract

The paper presents a drilling fixture that fits on the EMCO MILL 55 CNC working table for machining the holes of some blanks made of materials having low and average hardness. The modeling was carried out with Autodesk Inventor software package, highlighting the essential controls, from basic sketches to the completion of the component parts, respectively the final assembly. At the same time, the paper presents a brief theoretical calculation of the necessary force for fixing the blank into the fixture. Based on the fixture elements, the physical model of the drilling device was drawn. Moreover, a double- straight edged helical drill used for the drilling process was modeled in CATIA environment.
