Research Regarding the Development of an Android Application Presenting Measurement, Drawing Indications and Explanations for Roughness Parameters

This paper presents an android application developed for engineering students aiming to help them develop their skills to correctly interpret roughness parameters and their measurements according to the ISO standards. Due to the evolution of technology in the past 20 years and the need to constantly keep up with it, the learning and teaching process suffered a massive change. Students nowadays are high-tech learners, and they use their mobile devices in the learning process. Surface roughness is a critical factor that affects the performance and functionality of the engineering components. It is essential for the engineering students to understand how to measure and analyze the roughness parameters in order to ensure the quality and efficiency of the different machined products. The developed application provides guidelines for measuring different roughness parameters, according to ISO 4287, ISO 4288 and offers details regarding the indication of roughness parameters according to ISO 1302. The application also presents ranges of values for Ra and Rz obtained through different machining procedures. The aim of the developed application is to improve the quality of the teaching process of Tolerances and Dimensional Control and 3D Modelling courses for engineering students, covering the following lines of studies: design, robotics, industrial and mechanical engineering.
