Unconventional Technology (FSI-HNE)

The aim of the course is to provide detailed information about technological processes applied for moulding and machining by the use of unconventional technologies. It will predicate possible consequences of these processes and their impact on the post-procedural state of the workpiece from the distinctive level of the integrity of the worked surface. Future technologists and engineers will be provided with the fundamentals necessary for an optimum and qualified decision making in terms of the engineering technology.
The students will get acquainted with their use in the industrial practice for atypical manufacturing processes. They will be able to create production processes and applications of unconventional engineering technologies for new products. They will learn the methodology necessary for determining whether the proposed unconventional technology is economically and ecologically effective.

Knowledge of fundamental methods of machining and forming. Knowledge of physic on the secondary school level.

The course is intended to extend knowledge of the engineering technology, especially of moulding and machining parts, concentrating on the production and working engineering production components. It introduces progressive unconventional technologies
in the interaction: machine – tool – workpiece. For this purpose the student will familiarise with fundamental methodology of the theory for processes of beam method of the machining – laser, plasma, water jet, ultrasonic, electrospark, chemical maschining as typical
representatives of working hard workable material.
