Course detail

Unconventional Technology

FSI-HNEAcad. year: 2011/2012

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.

Aims

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.

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

Missed lessons will be compensated in alternative exercises by arrangement with the teacher.
