Some Aspects of Visualization as the Tool of Education Process Quality Increasing

Abstract

Abstract. The article deals with some aspects of visualisation as the tool of education process quality increasing at technical universities. There is described the sequence of 3D modelling activities that students have to pass in order to be successful in the study and consequently in practice. First, they learn to create simple parts, then they learn to assemble the components into the static or welded assemblies, respectively into movable mechanism. In higher levels, if they absorb the fundamental theoretical knowledge, they can subject the 3D models to the analysis, as are stress, kinematic, dynamic analysis, etc. and compare the computer aided results with the values calculated in classical way. Students can apply the other advantages of the virtual models into the drawings preparation in electronic form and at the tool path verification during the machining simulation. The whole production process can be designed by students, too. They can use several CAD/CAM systems for all activities listed above and compare results to verify the solution.

Improving Quality in the Process of Hot Rolling of Steel Sheets

“…When solving a problem, it is important to find out the real cause of the problem. An incorrectly identified cause may in fact only be a manifestation of the root cause [29]. By analyzing the results obtained by individual analyses, the root cause can be determined [30][31][32].…”
