Design and Fabrication of Indexing Setup for Industrial Drill Jig

An automatic indexing drill jig has been designed and fabricated and installed in a drilling machine. It is a supporting device which holds the work, guides the tool and also locating work piece in its position during machining/drilling process. The main purpose of indexing drill jig is to eliminate the process of marking on the work piece according to the dimensions provided before machining the component and thus the high accuracy is achieved. Drill jig can also perform operations like ream and tap at a sufficient speed and with required accuracy as compared to the process of creating holes conventionally by hand. The role of operator to maintain the accuracy in the process is replaced by the drill jig because of its capability for guiding, clamping and locating of tool and work piece respectively according to the need. The automation in the drill jig is incorporated to make the work easy and accurate. By automation process the advantages like reduction in human errors and idle time is reduced, which increases the production rate.
