The training course "Mechanical Materials Processing - Turning Part" deals
with the machining production processes of turning in accordance with the
training framework plans for metal professions (Lfd. No. 12 c "Turning"). The
various turning skills such as centering, drilling, thread production, taper
turning, knurling and deburring are dealt with in detail. A second focus is on
the lathes and their functions, as well as on professional operation and the
testing and adjustment of machine functions. In addition, the tools, the
alignment and clamping of tools and workpieces are described.
Various
project tasks are dealt with in 12 practical exercises, each with work
information, parts lists and work planning forms as well as control and
evaluation sheets. The exercises are structured according to the lead text
method and follow the model of the complete action. Thus they are particularly
conducive to action and social competence. The exercises can be worked on both
individually and in groups.
The complete training course in a collective
folder, consisting of the trainer's set with trainer's guide, slides on CD, text
volume, learning success controls and suggested solutions as well as the
documents for the trainee.
