Course detail

Machine Design

FSI-2KAcad. year: 2020/2021

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.

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.
