Supervisor: doc. RNDr. Libor Mrňa, Ph.D.  
Supervising institute: ÚST all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The objective of the course is to acquire a view of possibilities of computer support utilisation in technology and to acquire bases of a working manner in particular areas of this subject. The students will have a view of what they can expect from computer support results in practice. They will learn to work with simulation software based on finite element method in area of computer aided forming, welding and heat treatment.
Learning outcomes and competences:
The students will acquire practical experience in the theory, as well as the latest knowledge in CAD-CAM. Students will obtain the basic skills and experience of projects elaborating in numerical simulations of metal forming, welding and heat treatment.
Prerequisites:
Basic knowledge of engineering technology and computer literacy.
Course contents:
The lectures and seminars will enable students to acquire knowledge of mostly exploited regions of computer support in technologies of forming, welding and heat treatment. The basic part of the course is the work with simulation software using the finite element method and mastering the fundamentals of using software in direct support of technologists work. Mastering the work with above-mentioned software enable assessing of manufacturing process conditions and data necessary for determining of the optimal manufacturing technology for required part. The students will acquire basic experience for an individual orientation in problems of numerical simulations and analyzes using the finite element method.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
Conditions for awarding the course-unit credit are active participation in the class and elaboration of fractional tasks. The course is finalized with the graded course-unit credit. It is classificated by using the ECTS grading scale.
Controlled participation in lessons:
Attendance in lectures is recommended. Attendance in exercises is compulsory. The attendance to the seminar is regularly checked and the participation in the lesson is recorded. The missed lesson is possible to replace with another study group in the same week. In case, that the lesson does not possible to replace, the teacher may in justified cases set an additional task.
