“…Today, the concept of retrofitting is a common principle in the pursuit of renewing outdated machine tools. Retrofitting is defined as steady modification of an existing machine tool and comprises activities such as turning-off or replacing components of machine tools such as electrical components and control system to save energy, and minimize downtime [2,8]. Additionally, these cost-effective solutions of automation are equally beneficial to small, medium and large industries.…”

today, the concept of retrofitting is a common principle in the pursuit of renewing outdated machine tools.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, mean-time 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.

“…It will improve mean-time between failures and mean-time to repair. Additional benefits can be realized in energy savings, performance improvement and improve access to manufacturing data [1,2,6,8,9]. Implementation of quick and efficient industrial processes is the main objective for any manufacturing company.…”

“…By starting from an input-output schematic framework, [5] develops a mathematical model, based on matrixes whose coefficients reflect the dependence between the manufacturing system inputs and outputs, from quantitative point of view, grounded on the conservation of matter principle. In [6], an approach for machine tool (lathe) energetic modeling is presented together to formulas for calculating the power demanded by main generic parts of a machine tool (motor, pump, compressor, and other constant consumers). Moreover, in [7] a machine tool behavioral model is used to improve the scheduling of energy saving modes.…”

A product manufacturing involves, automatically, an amount of carbon emitted in the atmosphere. This carbon amount is determined by the consumption level of the resources in the manufacturing process, namely the consumed material and energy. The researches concerning the environmental impact issued by the manufacturing process are based on several concepts like carbon footprint and specific energy consumption, in order to reveal solutions for diminishing this impact. Here, we are introducing a deeper approach of the same issue, grounded on a broader meaning of the environmental impact concept. We are also suggesting a dedicated indicator to measure this impact: the ecological earning power (EcoEP), which is defined by making a connection between the earning power and the environmental impact, judged at the same level (be it the process / operation / job / order / manufacturing system level). EcoEP represents, in fact, a trade off between the economical target of the manufacturer (to earn) and the consequence of its actions, regarded from ecological point of view.

“…Retrofitting is primarily understood as steady modification of an existing machine tool and comprises activities such as turning-off or replacing components of machine tools to save energy, or the exchanging out of key wear parts (Gontarz et al 2012). These activities target a machine tool, its auxiliary systems or the machining process itself.…”

Environmental, economic and social changes of any significant proportions cannot take place without a major shift in the manufacturing sector. In today's manufacturing processes, economic efficiency is realised through high volumes with the use of specialised machine tools. Change in society, such as in the form of mobility and digitisation, requires a complete overhaul in terms of thinking in the manufacturing industry. Moreover, the manufacturing industry contributes over 19 % to the world's greenhouse gas emissions. As a consequence of these issues, a demand for sustainable solutions in the production industry is increasing. In particular, the concept of "cost" in manufacturing processes and thus the "system boundaries" within the production of the future has to be changed. That is, a great number of aspects to the machine tool and production technology industries can be improved upon in order to achieve a more sustainable production environment. Within this chapter, the focus lies on microsystem technology enhanced modular machine tool frames, adaptive mechatronic components, as well as on internallycooled cutting tools. An innovative machine tool concept has been developed recently, featuring a modular machine tool frame using microsystem technology for communication within the frame, which allows for a high level of flexibility. Furthermore, add-on upgrading systems for outdated machine tools-which are particularly relevant for developing and emerging countries-are poised to gain in importance in the upcoming years. The system described here enables the accuracy of outdated machine tools to be increased, thus making these machine tools comparable to modern machine tool systems. Finally, the cutting process requires solutions for dry machining, as the use of cooling lubricants is environmentally damaging and a significant cost contributor in machining processes. One such solution is the use of internally cooled cutting tools.
