Computers in Modern Manufacturing

COMPUTERS IN MODERN MANUFCTURING INTRODUCTION Computers play priceless role in youthful manufacturing. In fact, nearly all modern manufacturing declare systems are implemented victimization computer systems through automation. It reduces manual work in manufacturing and production. Computer Integrated Manufacturing(CIM) is the terminology practice sessiond to pick up the complete automation of a manufacturing plant. CIM involves integrating the functions of figing products, production preparedness, in operation(p) control and business-related functions in one system that operates throughout the enterprise.All of the processes function on a lower floor computer control. Digital information ties them altogether. The different computer controlled processes are as follows -aided design , computer-aided manufacturing pawl/CAM The heart of CIM is firedog/CAM. Computer-aided design( firedog) denotes the use of computer systems to support the product design function. Using wiene rwurst, it is possible to simulate in cardinal dimensions the movement of a activate through a production process.Computer-aided manufacturing (CAM) denotes the use of computer systems to perform functions related to manufacturing engineering, such as process planning and numerical control(NC) part programming. Some computer systems perform both heel and CAM, and so the term hound dog/CAM is use to indicate the integration of the twain into one system. bounder/CAM is concerned with the engineering functions in both design and manufacturing. The method of manufacturing a product is a forthwith function of its design.Through CAD/CAM technology, it is possible to establish a direct link between product design and manufacturing engineering. They have together oercome traditional NC shortcomings in expense, simple mindedness of use, and speed by enabling the design and pay off of a part to be undertaken using the same entropy encoding system. CAD/CAM has as well as given the de signer much more direct control over the manufacturing process. ADVANTAGES CAD/CAM changes manufacturers to reduce the costs of producing goods by minimizing the involvement of human operators.They enable manufacturers to make quick alterations to the product design and obtain instant results. overly there is no risk of human(repetitive) error. This finally results in lower operative costs, lower end product prices and increased profits for manufacturers. CAD/CAM systems also facilitate communication among those involved in design, manufacturing, and other processes. This is of particular enormousness when one firm contracts another to either design or start out a component.DISADVANTAGES There are no means of comprehending real-world concepts in CAD systems, such as the nature of the object being designed or the function that object will serve. CAD systems function by their efficiency to codify geometrical concepts. Thus the design process using CAD involves transferring a de signers idea into a formal geometrical model. Thus CAD cannot build the exact design as it is on the designers mind. Also, there are several limitations of CAM. Setting up of infrastructure to obtain with is really expensive.CAM requires not only NC machine incisions themselves but also an protracted software product and hardware to develop the design models and convert them into manufacturing instructions. The output from the CAM software is usually a simple text file of G-code, sometimes more thousands of commands long, that is then transferred to a machine tool using a direct numerical control (DNC) program. CAM packages still cannot reason like a machinist. The depicted object of computer-aided management is fraught with inconsistency.While all numerical controlled machine tools operate using G-code, there is no universally used standard for the code itself. CAD systems tend to store data in their own proprietary format, so it can often be a challenge to transfer data from CAD to CAM software. There are some problems with CIM also. Existing equipment and software may be incompatible with each other leading to expensive updates or replacements. Extensive programming may also be required to obtain optimal schedules and part sequence.CAE Computer Aided plan (CAE) systems are very useful systems for engineering area. Integrated or independent CAE systems are used by design engineers and specialists. Computer simulation is very significant tool for designers. The reason is to understand to the behaviour of the technical systems before their prototype production. therefrom many analytical programmes have been created in the last thirty years for engineering area. These programmes are entitled as Computer Aided Engineering (CAE).UTILISATION OF CAD/CAM SYSTEMS PRO/ technologist Pro/ENGINEER is full tilt 3D graphic CAD/CAM system, determined mainly for general manufacture engineering and for automation of design engineering. With graphical system Pro/ENG INEER is able to create fully, unambiguous and accurately spaced model of comforting body simply and quickly. CONCLUSION Utilisation of CAD/CAM systems is highly hard-hitting because it enables to reduce the process development time and the introduction of a overbold product in the market in a large scale. new-fangled technical developments have fundamentally impacted the utility of CAD/CAM systems.For example, the everincreasing bear upon power of personal computers has given them viability as a vehicle for CAD/CAM application. Another important development is the establishment of a single CAD-CAM standard, so that different data packages can be exchanged without manufacturing and delivery delays.REFERENCES 1. Groover, M.
