Aims
In this subject, students will get acquainted with the preparation and use of data needed for 3D scanning of models and castings, for numerical simulations and virtual engineering. Students will learn about the basic methods and principles of the RAPID PROTOTYPING (RP) technology, including reverse engineering procedures (RE). They will get familiar with the selected modern technologies for manufacturing castings and process management methods with the application of the industry 4.0 principles. They will also learn model surfacing procedures and methods for RP, molds and castings and they will get acquainted with the dimension and shape accuracy testing methods and metallographic and phase casting material assessment methods. Part of the subject will also be to obtain knowledge of the composition of production costs and the foundry production economy.
Specification of controlled education, way of implementation and compensation for absences
Participation in lectures is recommended. Participation in seminars is compulsory. Comprehension is checked in seminars. The tutor gives the students individual tasks. Missed classes need to be discussed with the guarantor.
