Course detail

Numerical Modeling and Rapid Prototyping

FSI-HRA Acad. year: 2020/2021 Summer semester

The course is focused on modern technology and modern methods used in the development, design and manufacturing of a prototype. At the beginning the term “Computer Aided Design” is defined along with its integration into the production process. Next, CAD systems are dealt with in more detail, systems separated into categories and the use of each category is explained with a view to working methods and available tools. Part of this subject is concerned with collaborative design between computerized workstations over a network (LAN). The final part concerns prototype product description various methods of rapid prototyping and efficiency reverse engineering methods.

Learning outcomes of the course unit

Students will have an overview of CAD system and Rapid Prototyping technology properties used in the design and construction processes and in prototype manufacturing and 3D scanning techniques.

Prerequisites

Basic knowledges about design of machine parts and machine nodes.
Knowledge of computer control., CAD basics.

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: The student has to be able to explain the suitability of selected solution and applied procedure, objective accuracy of computational and documentation part of the report. The mark reflects also the graphic and formal sides of the report.

Aims

The course explains the principles of Computer Aided Design systems and methods of prototype manufacture especially of rapid prototyping and reverse engineering – 3D scanning

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

Participation in the exercises is obligatory and is controlled by the teacher. Absences can be compensated in exceptional and well-founded cases – to be determined by the course supervisor.
