FSI-HTNAcad. year: 2017/2018
The course deals with following topics: Types of forming tools - simple tools, follow-tools, combined tools, compound tools. Also dealt with is the design of tools for cutting, punching, blanking, bending, deep drawing, extrusion, forging. The course focuses also on the design elements of tools including technological and design computations, materials for tools as well as on special tools for small number of products.
Learning outcomes of the course unit
Students will acquire knowledge of the tool design, as well as skills mecessary for proposing a concept of a tool for various forming technologies including application of design parameters.
Knowledge of forming technology. Knowledge of engineering drawing, rules for fitting, types of materials for tools. Knowledge of stress analysis and technological steps.
