Course detail

Machine Design

FSI-2K-A Acad. year: 2020/2021 Summer semester

The course provides students with knowledge in the field of creation of design documentation (mostly drawing) with a focus on technology and serial production. Teaching is focused mainly on the creation of drawings of cast, forged, welded and other components. Attention is paid to the calculation of functional dimensions and their tolerance. Emphasis is placed on the optimization of functional and technological dimensioning in the creation of complete drawing documentation of the assembly unit. Students will gain basic knowledge of current trends in the creation of documentation. The course also complements the basic knowledge of selected types of machine parts.

Language of instruction

English

Number of ECTS credits

4

Learning outcomes of the course unit

• knowledge and ability to process drawing documentation of products from cast, forged and welded semi-finished products
• the ability to create assembly unit documentation with an emphasis on ensuring function and interchangeability
• knowledge of preliminary calculation and documentation of gears
• basic knowledge of modern trends in the creation of design documentation

Prerequisites

The condition of the study is successful completion of the subject Machine Design Fundamentals (1K).
Knowledge of the basics of design (basics of technical drawing, drawing documentation, dimensioning, geometric tolerances, basic principles of functional and technological dimensioning) and a clear knowledge of materials science (material selection and its standardization) are necessary.

Planned learning activities and teaching methods

The course is taught through lectures and exercises which are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Terms of graded credit: attendance at seminars, elaboration of graphic projects (programs), graduation of tests and work tasks. Students must complete all four conditions. Final classification according to ECTS.

Aims

Graduates will be able to create basic documentation of machine parts, whose semi-finished product is casting, forging or weldment, they will also have knowledge of the complete drawing documentation of the assembly unit, including basic dimensional calculations.

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

Attendance at seminars is mandatory and controlled. Maximum of two authorized absence without compensation of lesson are allowed.
