Subject aims expressed by acquired skills and competences

Students after completion of the course will focus on issues of special machine construction plant. They will learn the principles of the constitution and clamped workpiece in products with security capabilities required by the production of precision products and resources that can be used for clamping. A practical verification of acquired knowledge is developing its own project preparation for machining a particular part.

Summary

Lectures subject develops chapters connected with fixative equipment construction. It is based on knowledge of subjects: Flexibility and fixity, Machine parts and Mechanics. During the lectures frame students familiarize their selves with principles of workpiece establishment and its clamping in advance working, with basic elements for mechanical, pneumatically and hydraulic workpiece clamping, with production precision during cutting in advance period and with the basic characteristics of special, universal, associated and constructional fixtures. In the lectures framework students work individually construction design on the concrete technological procedure operation of given detail. After lectures termination is graduate able to solve individually construction for appropriate cutting operation.
