Course detail

Computer Aided Technology

FSI-DPPAcad. year: 2016/2017

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.

Aims

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 in area of computer aided forming, welding and heat treatment.

Specification of controlled education, way of implementation and compensation for absences

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.

Recommended optional programme components
