Abstract: In recent generations, significant development in manufacturing processes has led to large advancements in the process of machining. . However, for converting the raw material into the given desired part, one of the most important processes is called as shaping. In the case of a normal existing shaper, the tool feed to cut the work piece will be given manually. However, in certain cases, there is also automatic feed control. In the case of our method, we propose an automatic feed control by integrated works of mechanical, electrical and coding software. In this method, the tool slide which is kept normal top the work piece or swiveled at an angle, initially moves over the work piece. The entire unit is connected to the internally connected microcontroller circuit. Once the first action of the work piece removal is done, the microcontroller is automatically coded to stimulate mechanical action, by means of which the dial indicator moves to check the flatness of the already cut work piece. Indicators may be used to check the variation in tolerance during the inspection process of a machined part, measure the deflection of a beam or ring under laboratory conditions, as well as many other situations where a small measurement needs to be registered or indicated. [5] Once the secondary action is completed, the deflection detected by the microcontroller is detected in the case of the work piece being uneven and the tool slide is instructed by the microcontroller to move to the deflected point by stimulated mechanical action. Again the dial indicator is moved to check flatness; until the deflection is not detected the above process continuous to occur and finally stop when no deflection is detected. One of the major advantages of using this method of automatic feed is that it is fully automated. Since a dial indicator is also used to check the flatness, the accuracy obtained in the flatness of the work piece will be maximum. It also eliminates the human operator thus diminishing human error.
