Course detail
Tool Jigs and Fixtures for Machining
FSI-HUP-KAcad. year: 2021/2022
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.
