In the current article, three of them are investigated in the case of the ball-end milling of a convex and concave cylindrical surface form 42CrMo4 steel alloy. The accuracy can describe dimensional, geometrical, and surface roughness parameters. The produced part and machining process should satisfy the working, accuracy, and financial requirements. The machining of free form surfaces is one of the most challenging problems in the field of metal cutting technology. Students are hi-tech learners, and they are in trend with current technological innovations in education. They are using this mobile application integrated into the engineering courses students transmitted positive feedback. In 2018 we published the educational android application ISO Checker. This paper also presents the advantages and disadvantages of the published applications. The authors conducted a detailed analysis of the educational applications presenting geometrical tolerances available in Google Play. The educational applications used on mobile devices develop a friendly environment and generate a positive effect on learning. The previous studies focused on mobile learning’s impact on student achievement show that the method could be one of the promising educational technologies. This application aims to improve the quality of tolerances and dimensional control and 3D Modelling courses for engineering students, covering the following lines of studies: design, robotics, industrial and mechanical engineering. The research aims to develop a mobile learning engineering application, presenting the form deviations according to ISO 1101.
