The graphic and geometry education quality control for specialists in CAD / cam systems by means of cognitive competence forming

The paper presents the results investigations of the "Designer – Program – Model" system study during the computer-aided geometric modeling lessons. The influence of students personal characteristics over the design solution quality, derived with the help of educational CAD/CAM environment is considered. The proposed principles of educational process improvements are used at “Aircraft engines” department of SSAU during the concurrent end-to-end grapho-geometric trainings of technical engineers.
