<abstract xmlns="http://www.w3.org/1999/xhtml">To consistently produce high quality products, a quality management system must be practically implemented in every organization. One of its core instrument is to ensure the capability of the measurement systems, which are the basis for decisions regarding the behavior of the product critical quality characteristics. Base on requirements of the quality management system, a Measurement System Analysis should be conducted for all measurement system which are mentioned in the organization quality plan. Most problematic measurement system issues come from measuring discrete data, which are usually the result of human judgment (subjective decision) when categorizing products such as good/bad (visual inspection). It was the aim of this paper to address such an issue presenting a case study made in a local company from the Sibiu region, in order to evaluate how capable are the appraisers to visually inspect steel chains. The results were analyzed using MINITAB statistical software with its module called Attribute Agreement Analysis. The conclusion was that the inspection process must be improved by operator training, developing visual aids/boundary samples, establishing standards and set-up procedures.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">With the uptake of the IoT in the industrial domain, a whole new range of cyber-physical systems has emerged; Industry 4.0 is the title given to this technological domain of highly interconnected, data-rich systems. To aid the development of such systems, a range of reference architectures has been developed throughout the years. This paper reviews a number of recent reference architectures, detailing their essential traits as well as identifying aspects that need to be further explored in order to obtain reference architectures better tuned to generating cyber-physical social systems.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The paper analyzes the process of internal honing of cylindrical gears, a new and modern method of finishing the gear tooth flanks. At the beginning, the kinematics of the process is being analyzed. By realizing the state of art, we were able to identify the main features of the process, its advantages in terms of surface precision and quality, the residual stresses and the wear of the flanks compared with other finishing processes. An experimental study of the geometric precision, the shape of the flanks and the roughness for honed surfaces compared to the unfinished ones, highlighted the value and the need of this process.</abstract>

Development Overview of a Smart Customizable Product

<abstract xmlns="http://www.w3.org/1999/xhtml">Due to the fact that the requirements of the industry aim to improve the dynamics, the safety and the comfort during the use of the vehicles, it is recommended to use the finite element method for component quality optimization. The purpose of this paper is to provide an overview of the current state of analysis through the finite element method of the crimping process used to assemble air springs produced in the automotive industry. Starting from the prototype of an air spring, the researches are focused on the study of the assembly of the piston with the bellow and the crimping ring through the crimping process. After analysis with the finite element method and static tests, improvements were made to the piston, the results of the tests revealing an improvement as opposed the original variant of the piston.</abstract>

Crimping Profile Optimization on the Air Spring Using Finite Element Method

<abstract xmlns="http://www.w3.org/1999/xhtml">This article presents the study of three-dimensional, stagnation flow of a Powell-Eyring fluid towards an off-centered rotating porous disk. A uniform injection or suction is applied through the surface of the disk. The Darcy law of porous disk for Powell-Eyring fluid is also obtained. The governing partial differential equations and their related boundary conditions are converted into ordinary differential equations by using a suitable similarity transformation. The analytical solution, of the system of equations is solved by using homotopy analysis method. The convergence region of the obtained solution is determined and plotted. The effects of rotational parameter, porosity of the medium, the characteristics of the non-Newtonian fluid and the suction or injection velocity on the velocity distributions is shown by graphical representation.</abstract>
