Metody oceny:
The knowledge and skills of students are assessed regularly during classes and through tests. Each of the four test is assessed in scale from 0 to 5 points. The performance during classes e.i. solution of exercises, tasks and problems during classes at the blackboard in front of the group as well as individually under supervision and assistance of lecturer. For corect answer student can earn extra 0,5 point. The final assessment is established on the basis of the total number of points obtained in the semeste. To complete the course student shall collect more than 11 points (above 11. 0 to 12,5 final mark 3. 0; above 12. 5 to 14. 0 final mark 3,5; above 14. 0 to 16. 0 final mark 4. 0; above 16,0 to 18,0 final mark 4,5; above 18,0 final mark 5. 0.

Profil ogólnoakademicki - wiedza

Efekt 1150-PE000-ISA-0205_W1
Student understands that geometrical deviations and measurement uncertainties are inherently associated with all manufacturing and measurement processes. Real workpieces always have form, orientation, location and run-out deviations while the designer task is to apply tolerances that limit maximum permissible deviations within which the workpices fulfils requested functional requirements. Student can identify fit type and is able to select shafts/holes to obtained particular fit.
