Programmable Logic Controller Controlled 360 Degree Flexible Drilling Machine

Abstract

This paper focuses on controlling a flexible drill machine using a programmable logic controller (PLC), so that the speed and time of drilling can be controlled and accuracy of the drilling could be increased. Hence, fabrication of the drill machine whose DC motor can be controlled using a PLC is discussed. The drilling machine finds its application in drilling in any direction (x, y and z) and at any angle which makes it work in 360 degree. Complicated parts having alignment problems could be drilled horizontally, vertically or even upside down. The components used and their specifications in fabricating drilling machine are discussed thoroughly. Parameters of machining, i.e., speed of cutting, rate of feed, cutting depth, material removal rate and time of machining of the drill machine, are calculated which makes it convenient to drill in materials like metals, wood and plastic.
