Assesment methods and criteria linked to learning outcomes
Credit: Participation and appropriate knowledge in courses, elaborating 2 technological projects in the course of a semester
Exam: Credit, numerical part of exam, verbal part of exam
Aims
The aim of course is to get knowledges about principles of design of cast details, about methods of casting technology development, the choise of optimum production methods, dimensions of pouring and riser system. Relations the casting technology to casting defects is discussed in details. A accent is given on economical optimation of the manufacturing method.
