today, the concept of retrofitting is a common principle in the pursuit of renewing outdated machine tools. The involvement of automation in conventional cutting machine becomes a must. It will improve meantime between failures, meantime to repair and will save energy as well. The wire cutting and straightening machine is selected to be retrofitted, because the machine is mechanically good.. And the retrofitting is based on a PLC control scheme. The machine used has specified length to suit the required length for the shelves and basket used in air cooler refrigerators plant, so it is a very important machine in the company production line, any failure in any part will cause a considerable delay in the final production line. PLC is a suitable the manufacturing environment [1]. This paper an attempt is made to replace the conventional control system with a PLC system in old machine. The result shows a good improvement in down time. There drop in down time percent from 86% and 23% in years 2014 and 2015 respectively to .0.08% in year 2018 after implementation of PLC.

Composite fibers are globally used in voluminous applications. The defense and aerospace industry is the largest consumer of prepreg for civil aircraft, military, jet, helicopters, aero-engines or space satellite launchers. Prepreg is a term of preimpregnated composite fibers in which a matrix material such as epoxy, silicon carbon fiber, etc. With the developme in technology in cutting where laser cutting has taken the lead being the most accurate yet unaffordable and time consuming. This paper refurbishes an old cutting technique merged with the automation technology, which gives an all new affordable solution to cutting of bulk materials, with good accuracy and less time consumption.

Automation is a key parameter of interest in all production processes. Raising the productivity is the main goal of every industry. The best way to improve production rates (productivity) is the use of special purpose machines which are widely used for special kinds of operations. In the present paper, authors have analyzed each and every process of power switch assembly manufacturing. By adding or modifying an automatic process, assembly cost can be reduced, which affects the overall cost of the product. So, an attempt is made to design to automate the cutting process. This paper concerns the proposed design, modeling and selection of the components using mechatronics approach. The design can meet the variation in cutting the length as well as the thickness of the rod. This is mandatory for various sizes of power switches.

Our everyday life comprises of an endless list of commodities and products which are made up of metal or metallic components. Metal is used in a wide range application from house wiring to the transport facilities that we use every day. Of all these day-to-day goods, the use of metallic sheets is proportionally high. The examples of their use include our kitchens, bathrooms, drawing rooms, study rooms, furniture, decoration, doors etc. To mold these sheets as per the requirement of the individual product requires skill and to put this skill to use, some machinery is required. There is a wide range of machinery used to mold these materials; change their shape, dimensions, surface finish etc. In order to put them through these changes, they are required to be cut to the exact dimensions as per application. A Shearing Machine is used for this purpose. The machine is a mechanical arrangement so as to provide mechanical advantage and reduce effort of the operator in cutting the sheets. A...

There are existing works based on CNC machines controlled by PLC. Most modern CNC machines use various programming methods such as implementation of GK-code, M-code, etc. In this paper, a novel design based on Fuzzy Inference System (FIS) is developed using B&R (Erwin Bernecker and Josef Rainer) Industrial Automation PLC (Programmable Logic Control) HMI (Human Machine Interface) for enhancing the real time performance of a Profile Cutting Machine is proposed. Its Objective is to design and develop two axis Profile cutting machine using PLC with Fuzzyand to visualize the working status using HMI. In this work static FIS is developed and implemented in the PLC controller to achieve the coordinates of the Profile. Instead of training the FIS for the new set of data, two more parameters are added externally to the output of FIS in order to adapt for variation in the Profile. As outcome the Profile cutting machine will cut in desired angles at desired positions by simply adding two more ...

In today's industries, several types of machines are present that can cut single bar at a time. Though single bar cutting machine also differs to its size and shape. Today automation and increase in production rate is main step companies are undertaking for faster and cheaper production. Recently during project work we have seen a machine that can cut a bar (100mm diameter) with automatic feeding and cutting, but machine we have designed can cut three bars at a time and design of this is unique. This Project gives the information regarding the design of the machine and its working. For automatic bar cutting, Holding and feeding operation Hydraulic cylinders are used. Basic view of this Project is to in increase Production rate.

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.

The Automation of processes plays a crucial role in improving the overall productivity of Industry. This paper give idea about the live industrial problem of EXCEL INDUSTRIES. It is the electrically automated, mechanically designed model of automatic plastic pipe cutting machine. The main aim is to improve the overall productivity by decreasing the manpower cost, utility cost and improving quality and quantity of production. Quality of production is improved by making the manual cutting operation fully automated ensuring the repeatability of the process with accuracy and precision. This ensures elimination of human error and monotonous work. Quantity of production is improved by avoiding manual delays and achieve quick response time of machine. It also focuses on optimum use of power provided for cutting operation.
