Burnishing is a machining process without chip removal that seeks to improve the surface roughness of a component by means of plastic deformation of the surface layers. Due to the process mechanics, during its execution, a compressive residual stress is introduced into the surface of the workpiece during its execution, which improves various physical-mechanical properties of the component. This process has been used industrially since the 1950s, mainly in pieces made of soft materials (hardnesses up to 45 HRC), in operations subsequent to processes such as turning. The development of tools with harder materials, has opened up the possibility of burnishing on harder materials (hardnesses up to 62 HRC). Burnishing of hard materials has opened up an alternative to traditional finishing processes such as grinding, its main comparative advantage is its low-cost operation, which reduces grinding costs by 8 to 15 times. The plastic deformation burnishing is a metal working process with material removal whose advantages are that it does not generate waste, which is a competitive advantage over other surface finishing processes such as grinding, where waste is generated which also needs to be collected and subsequently treated. The use of e.g. coolants is not necessary either, in recent years, attempts have been made to eliminate them from material working processes, because their presence not only causes a significant cost that impacts the manufacturing process, also represents an environmental problem due to its polluting effect, with the associated management costs involved. This article presents the results of an AISI 1045 test specimen experiment, to which a turning process has previously been carried out.

The reduction of the amount of pollution and toxicity by the manufacture of products has been a topic widely investigated by many international organizations, looking for an answer that help humanity to minimize the environmental impact. The main objective of this paper is to study the literature of Green engineering from 2007 to 2017 using bibliometric techniques for obtaining an overview of the production behavior of publications in this topic. The information was discharged and analyzed using tools such as Web of Science (WOS) and HistCite to get important results of the international contribution developing significant advances in this area. According to the results obtained, USA has been the most important country researching in this subject, providing 36.8% of the total publications. From the 257 publications, 60.9% were journal articles, where the Abstracts of papers of the American Chemical Society was the most relevant journal with 14 papers. Between 2014 and 2017 an important increase in the published production was presented, being 2016 the year with the most papers published with 15.6% of total investigations. In recent years, green engineering has been consider in many process on industries as a key tool to help the control of the greenhouse emissions, reducing the environmental impact providing some steps to achieve goals proposed for 2050 according to the ISO 50001 standard.Introducción.

The economy of the machining process is an important point that has been given attention since the beginning of the process. For this reason, this study focuses on the evaluation of the performance of the cylindrical milling process, varying the feed rate per tooth for the operating conditions proposed in the revised case study. This was done using a calculation algorithm in which the fixed parameters were entered and the feed per tooth was varied. Finding benefits in terms of cutting speed, feed speed, cutting time and more. Increased feed per tooth resulted in lower process costs.

The impact of materials is undoubtedly the object of research, due to the dynamic condition inherent in the bodies that interact in our universe. This work places special emphasis on the method of plate bending, which, due to its geometric configuration, interprets real impact situations to which some bodies are subjected, in addition to the low energy technique in which the energy available in the impactor is less than that absorbed in the breaking process, makes it possible to obtain information on the material in the elastic, plastic, initiation and crack propagation range. For research, the contribution of technological progress in instrumented test equipment by electronics is important, as it allows us to record much more information on the evolution of the contact between the impactor and the sample step by step. This information must be further processed and this phase of the research requires programming, modelling and simulation of the test dynamics to interpret or even predict the different phenomena that converge in the fraction of time in which the impact occurs. In this sense, our objective has been to study the physical behavior of different thermoplastic materials and their response to impact requests and to develop a series of models that try to simulate the phenomenon, in order to help us establish what happens at each stage of it, this is achieved using powerful mathematical tools, new contributions from the scientific community and continuous experimentation achieved in the laboratory. So that more knowledge can be obtained in this field.
