Abstracts: Many industry nowadays are using automation for there production process. Automation has great advantages over manual labour but setting up an automated machine is very costly like VMC, automatic turning center,CNC lathe. A conventional machine can we made to work as a CNC machine by changing guideway or fixture. Jobs of conventional upright drilling machine require positioning of drill over all holes location which can be done more easily by adjusting the guideway or fixture. The spindle is fixed so only option is to move the workpiece with help of fixture. It is also required to do marking on the workpiece which may raise problem due to error in marking by the operator. It will require more time and reduce production rate. Also the drill is required to be set at center of the hole. Our aim is to make an arrangement which will reduce the time consumed in marking the center of the hole on workpiece and to prevent the requirement to make jigs. Instead of making the whole guideway automated we will develop a fixture which will automatically adjust the center of the hole of workpiece. By using this method the production rate will be increased with minimum efforts of human.
