Design Parameters of Automatic Drilling & Tapping Machine

Abstract

Abstract: This paper focuses on design of machine which can perform drilling and tapping processes together with the help of automation in order to improves production, reduce time for manufacturing and manufacture economically on a bigger scale. In regular drilling process which is the most common way to put a hole in metal or other materials, for precise hole location, good finish and accurate size automatic drilling machine is required. To cut threads on hole accurately along with the drilling process we using drill cum tapping bit. Tapping operation required to rotate the spindle in both clockwise and counter clockwise direction. So, we have made bevel gear arrangement for reversal of the spindle and also worm and worm gear is used for speed reduction as drilling requires high RPM and tapping requires low RPM to perform the drill and internal threads.
