42211 Fundamentals of Metalworking
Danish title: Grundkursus i metalbearbejdning
Language:  Danish    ECTS-creditpoints:  10, External examination.   
Class schedule:   E4
Exam schedule:   F4-A (jun 04 2002), E4-A (dec 18 2001)
Recommended semester:  4th -7th semester
Scope and form:  Lectures, private study, problems exercises and experiments in the laboratory.
Evaluation:  Written exam and approval of exercises
Examination:  13-scale
Prerequisites:  42301
Aim:  The course will enable the participants to analyse metal forming and metal cutting processes and to assess the accuracy of the analysis. As well theoretical as experimental methods will be used. Consequently the course will produce a good understanding for the continuum mechanics of the processes and make possible the determination of a number of particulars that are determining the selection of process, process steps, component geometry and machine tool and for the practicability and reliability of the process and for the tolerances and mechanical properties of the produced component. Examples from modern heavy metal forming and -cutting will be given together with glimpses from the history of technology during the last two hundred years.
Contents:  13 mornings with theoretical work covering:
a) The basis for the technological theory of plasticity:
Yield criteria, flow rules, strain hardening hypotheses, formability criteria, friction models etc.
b) The methods of analysis:
Work method, slab method, sliplinie method and upper bound method.
c) The simulative methods:
Model material techniques, numerical techniques.
d) Analysis of processes within the areas:
Forging, cold forging, coining, extrusion, rolling, wire drawing, deep drawing, tube forming, stretch forming, bending, spinning, blanking, turning, milling and grinding.
13 laboratory afternoons covering:
a) Testing of technological properties of materials and friction (6 afternoons):
Examples: Cylindrical upsetting, plane strain upsetting, hardness testing, biaxial tensile testing, formability testing, ring test, cigar test, double cup test, twist-compression test.
b) Process investigations with metals and model materials. Measurement of force, temperature, geometry, hardness, deformation pattern. Comparison with theory (6 afternoons):
Examples: Forging, cold forging, extrusion, deep drawing, bending, blanking, turning, milling.
c) Conclusion (1 afternoon)
