Abstract: To understand the application and importance of the involvement of automation in conventional drilling machine in manufacturing. A drilling machine comes in many shapes and sizes, from small hand-held power drills to bench mounted and finally floor-mounted models. They can perform operations other than drilling, such as countersinking, counter boring, reaming, and tapping large or small holes. Because the drilling machines can perform all of these operations, this paper will also cover the types of drill bits, tool, and shop formulas for setting up each operation. Safety plays a critical part in any operation involving power equipment. This paper will cover procedures for maintaining, and setting up the work, proper methods of selecting tools, and work holding devices to get the job done safely without causing damage to the equipment, yourself, or someone nearby. Keywords: Pneumatic System, PLC. I. INTRODUCTION To evolve and admit automation by the involvement of various types of drives, cylinders and man motion study. In this paper it has been innovated that how we can use or convert conventional drilling process with the help of PLC, Pneumatic Cylinder, dc motor and sensors into the process. It is a time saving with good quality procedure. In the paper the various Man Motion has been done with help of cylinders. Such kind of conversion can be done easily anywhere where high volume with good quality to be produced. The industrial CNC machine components are fabricated using quality material and technology. These are available in varied sizes and diameter at the leading market prices. We ensure to monitor its quality before offering to our esteemed clients across the world. II. MANUFACTURING&APPLICATION A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials. Drilling machines use a drilling tool that has cutting edges at its point. This cutting tool is held in the drill press by a chuck or Morse taper and is rotated and fed into the work at variable speeds. Drilling machines may be used to perform other operations. They can perform counter sinking, boring, counter boring, spot facing, reaming, and tapping .Drill press operators must know how to set up the work, set speed and feed, and provide for coolant to get an acceptable finished product. The size or capacity of the drilling machine is usually determined by the largest piece of stock that ca n be center-drilled. For instance, a 15-inch drilling machine can center-drill a 30-inch-diameter piece of stock. Other ways to determine the size of the drill press are by the largest hole that can be drilled, the distance between the spindle and column, and the vertical distance between the worktable and spindle. The system aspects of manufacturing are more important than ever today. The word manufacturing was originally derived from two Latin words, Manus (hand) and factus (make), so that the combination means made by hand. In terms of the human participation in the manufacturing process performed by the manufacturing system following three categories can be distinguished: a) Manual work systems b) Worker-Machine systems c) Automated systems a) Manual Work Systems: A manual work system consists of one or more workers performing one or more tasks without the aid of powered tools. b) Worker-Machine Systems: In a worker machine system, a human worker operates powered equipment such as machine tool or other production machine. c) Automated systems: An automated system is one in which a process is performed by a machine without the direct participation of a human worker. III. DRAWBACK OF CONVENTIONAL SYSTEM In earlier era, drilling technology could not meet the needs of smart drilling system. Generally, manual and semi-automatic systems had serious reliability problems, did a poor job. Some problems regarding existing system are as follows- 1) Manual operation. 2) Discontinuous operation because of manual working less speed of operation. 3) Startup time is more. 4) Less production rate. 5) It cannot detect metal pieces in object. 6) Unsafe working due to more manual efforts. High maintenance. As my paper is based on automation so I will emphasize on it more. Before discussing on paper I would like to give a brief idea about automation. The automated elements of the production system can be separated in two categories:
