Desenvolvimento de modelos virtuais tridimensionais para apoio ao ensino de metrologia

Abstract

Among the chalenges of teaching the subject of Metrology in the courses of graduation in Mechanical Engeneering and Mechanical Production , one could highlight teaching the concepts related to operationg principles of many measuring instruments and the practices in laboratory. In both situations rises the limitation of number of instruments available for demonstration, associated to the lack of physical space in the lab to have room for the large classes, usually with 55 students. In order to minimize this dificiency and improve the access to the contents by the students, three dimensional models of measuring instruments are being developed. This way, the student can at any time, have access to coursware and interact with the measuring instruments, simulating their functioning, possible errors and solving proposed exercises. Three dimensional models are being developed with the open source computer software Blender, wich allows 3D modeling, animation and video making, broadly used for interactive content such as games, virtual walkthrough, etc. Another advantage offered by Blender is it’s capability of working in many operating systems, like Linux, MacOS, Windows, Solaris, etc. All the files and educational content being created are free and able to be distributed and improved by other students interested in this monitoring project. Other feature in study is integrating the courseware with the new Integrated System of Academical Activities Management (SIGAA). Currently the animations are being made in the use of the universal caliper rule and the three coordinates measuring machine.
