Course detail
Unconventional Technology
FSI-HNE-K Acad. year: 2021/2022 Winter semester
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.

Learning outcomes of the course unit
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.
Prerequisites
Knowledge of fundamental methods of machining and forming. Knowledge of physic on the secondary school level.
Planned learning activities and teaching methods
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
Course unit credit requirements:
-participation in the exercises,
-delivery of assigned papers.
The exam will be written and oral and the resulting classification will be in accordance with Article 12 and 13 of the current BUT Study and Examination Regulations.

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.
