Course detail

Tool Jigs and Fixtures for Machining

FSI-HUPAcad. year: 2013/2014

The course is focused on the fundamentals of designing of cutting tools, jigs and fixtures for machining. It describes individual projection systems for tool design, as well as procedures applied for designing of operational fixtures in compliance with the proposed technology. The students will acquaint with individual types of cutting materials and their use for designing of tools.

Aims

The aim of the course is to familiarise students with the fundamentals of designing the basic cutting tools and fixtures for machining. They will learn and manage designing tools in basic projection systems with the use of computer technology. Designing of operational fixtures in compliance with the proposed technology. They will get acquainted with individual types of cutting materials and their use for designing of tools in the given machining technology.

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

Participation in the exercises – 100%, excused absence – max. 10%. If the student exceeds the limit of absences, the director of the institute may permit individual compensatory assignments. Missed lessons may be in well-founded cases compensated in the given week with other groups.
