Subject aims expressed by acquired skills and competences
Student will be able to individual proposal of special cutting tool or fixture for cutting operation after graduating of this subject. Construction proposal of cutting tool he can supply about control of cutting geometry and conditions for production and maintainance. In case of fixture he supply accuracy of location and clampipng reliability for proposing variants.
Teaching methods
Individual consultations
Summary
Subject lectures develop into the deep chapters connected with tools construction of complicated geometrical shape. During the lectures students will obtain gradually theory basis and methodology of cutting tools design with form turning tools, with form milling tools, tools for spur gears production,
tools for worm gears production and tools for bevel gears production. Lectures subject also develops chapters connected with fixative equipment construction. During the lectures frame students familiarize their selves with principles of workpiece establishment and its clamping in advance working, with basic ele-
ments for mechanical, pneumatically and hydraulic workpiece clamping.
