Computer-aided Engineering - Studieemner

This is the study programme for 2019/2020. It is subject to change.

The course aims to provide fundamental understanding in principles and applications of computer-assisted technologies in the mechanical engineering discipline. It starts with the mathematical description of geometric modelling techniques and covers the important activities and processes in a product's life cycle such as CAD/CAM software, optimization, additive manufacturing, modelling mechanical systems, multibody dynamics analysis, principles of flexible manufacturing systems, concepts of concurrent engineering, reverse engineering and virtual manufacturing, process control, Computer numerical control (CNC), machines programming, production and process planning.

Learning outcome

Upon attending this course, the student is expected to have

the overview of main computer-aided tools in mechanical engineering
knowledge about the mathematical basics of different geometric modeling techniques
advanced understanding of concepts within design, manufacturing, optimization, automation, mechanical system modelling and additive manufacturing
general understanding of the interaction between CAE tools in design and manufacturing
sufficient skills in using 3D modeling tools, exchange of design and manufacturing data and rapid prototyping tools
knowledge about CAPP and related algorithms
general understanding about CNC systems and different programming techniques
knowledge about application of CAE concepts within the context of discrete type manufacturing (e.g. car) and continuous type production (e.g. Oil and Gas)
knowledge about design optimization and competence in using optimization tool boxes for example, in MATLAB.

Introduction to computer-aided technologies in engineering field, principles of geometric modeling, mathematical basics for product models, examples in using advanced CAD/CAM software, generating 3D-CAD (volume) models for free-form objects, introduction to rapid prototyping and additive manufacturing (layer manyfacturing) technology. Principles of flexible manufacturing and concurrent engineering systems, reverse engineering and virtual manufacturing. Design optimization, mechatronics and control of industrial processes. CAD/CAM data exchange. Computer numerical control (CNC) machines programming (MAZATROL), CAM based on STEP, computer aided process planning (CAPP), group technology (GT) and cellular manufacturing.

Required prerequisite knowledge

None.

Recommended previous knowledge

Basic knowledge in machine design, computer-aided design and manufacturing (CAD/CAM), production and manufacturing engineering and applied mathematics. Competence in MATLAB programming is an advantage.

Exam

Project work and written exam

	Weight	Duration	Marks	Aid
Project work	4/10		A - F
Written exam	6/10	4 hours	A - F	Valid calculator.

The evaluation has two parts: digital written exam 4 hours and project work.
Written exam is weighted 6/10 and project work 4/10 of the total grade. The project work is presented for the class.
Both parts must be passed to obtain an overall pass grade in the subject.
