2. edition 2014, approx. 190 pages in a folder, with CD-ROM
The training workbook "Machine-based Material Processing - Part: Turning" deals with the metal removing process of turning in accordance with industrial training regulations for metal working occupations. It provides a detailed description of the main skills applied in turning, such as centring, drilling, thread cutting, taper turning, knurling, and deburring. It also presents the various types of lathes and their functions and provides instruction in professional machine operation. Detailed information is given on the checking and setting of the production parameters, and the necessary tools as well as the fitting and adjustment of the tools and workpieces is described.
A total of 12 practical exercises dealing with a variety of project tasks and each
accompanied by work information, parts lists and work planning sheets as well as
inspection and evaluation sheets, are contained in the workbook. The exercises themselves
are structured according to the "Leittext" method and are based on the end-to-end
process model. This approach fosters both working and social competence. The exercises
are equally suitable for individual and group work.
