Aspects Regarding the Modelling of Geometric and Strength Calculations of Worm Gears Using CAD Applications
The new processes of plastic deformation of the gears eliminate some of the shortcomings of the old methods of their manufacture, while reducing the production costs and the time of production in series. This scientific paper addresses the issue of worm gears. The focus has been on geometric and strength calculations for this type of gear, using different CAD applications. The use of these applications substantially reduces the time before the actual development of the processing activities, as well as the early encounter of possible problems.
Device for Processing Micro-bores by Electrical Discharge Machining
In recent years, there has been a growing trend to miniaturization parts. As a result, the processing technology must be partially evolved to produce a small surface, and then a microscopic surface. There are many of these technologies, and each has its advantages and disadvantages in the industry. Among these technologies, electric shock processing is used as an alternative with the required precision. Processing of very small wells by the method of electric emission is similar to that used in the processing of normal-sized machines and will be noted on paper. In this research, the authors developed a device for drilling holes 0.01–1 mm in diameter that can be installed in traditional non-…
Dynamic Simulation of Worm Gears Using CAD Applications
The new processes by plastic deformation of the gears eliminate some of the shortcomings of the old methods of their manufacture, at the same time reducing the production costs and the time of realization of the mass production. To carry out this research, the AutoDesk INVENTOR PROFESSIONAL application was chosen. A worm gear was designed, after which the calculations for the worm and worm wheel were performed. Of particular importance for gear, mechanisms are the research of dynamic loads. The use of modern calculation methods, which have wide possibilities for rapid optimization of prototypes, ensures the minimization or sometimes even exclusion of the execution of experimental samples. T…
The Rise of Distributed Artificial Intelligence Through Shared Data and Cloud Solutions
Decision-makers of present times encounter influence by an ever-increasing emotional condition created by social media, market trends, experience, and historical facts. The concept of mixed human and artificial intelligence is one of the most underrated business drivers today, and conspiracy theories, fixed mindset, and legacy systems are slowing down collective evolution. This paper intends to contribute to the everyday awareness of data sharing through cloud solutions and services. It opens a wide range of possibilities for new solutions and insights that endorse a collaborative culture where a growth mindset paired with transparency and ethics reduces time-to-value in businesses, governm…
Study of the cutting process parameters that influence the surface quality machined by end milling of the aluminum alloy
This research aims to carry out an elaborate experiment by witch resulting in relevant conclusions that have practical applicability in the aeronautical industry. The surface roughness measured transversely and longitudinally on the feed motion direction of the cutting tool constitutes the dedicated objective function on which the study was conducted in this case. The end milling was chosen of an aluminum alloy used explicitly in the aeronautical industry. The actual experiments were carried out in the only aeronautical industry in Romania carrying out these types of machining and were made according to the methodology with rigorous experimental planning of the research. The experimental pl…
Management of intelligent transport systems applied to sustainable development of motor vehicle transports
The scientific paper presents a concrete research carried out by the authors in order to implement technical concepts, so that those interested in this field can learn about a certain way of exposing the problems with regard to the sustainable development of road transport. The use of computer means in the field of motor vehicle transport have taken on a special magnitude in recent times, and the Intelligent Transport Systems (ITS), also known as telematics systems used in the field of transport, comprise a wide range of tools and services deriving from ITS technologies, by using communications and information technology. Below we present a technical and managerial study with engineering nu…
Experimental Research on the Cutting of Metal Materials by Electrical Discharge Machining with Contact Breaking with Metal Band as Transfer Object
The scientific paper presents practical research carried out by a mixed team of Romanian researchers from universities and the business environment. The research consists in applying the process of cutting metallic materials through electrical discharge machining with contact breaking using a metal band as a transfer object. The research was implemented with the help of a specially designed installation in the laboratory and subsequently all the necessary steps were taken to obtain the patent for it. Various metallic materials were cut using this process, but first of all, high alloy steels. In the global research conducted by the authors, active experimental programs and classic experiment…
Approach to Product Quality Requirements in the Context of Aeronautical Domain Process Modeling
Structural components account for a significant proportion of the number of components in an aircraft. The manufacturing methods and techniques by which these products are made, are considered critically, due to the importance of components. The volume and complexity of the requirements of each product are quite high. The intend of this research is to address the interaction of the product requirements in the manufacturing phase, when the value of the product increases the most, reason why the interest is highest. The requirements regarding the realization of the manufacturing processes, specific to the aerospace field, aim at the technological process parameters and are requirements genera…
