| Summary |
|---|
Subject lectures develop into the deep chapters connected with tools
construction of complicated geometrical shape. It is based on constructional
geometry knowledge, mathematics and kinematics. 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 and tools for worm gears production. Lectures content is aimed on realization of concrete tools construction proposals including tracing documentation elaboration, cutting geometry control and technological process production. After graduate lectures students be able to separately solve problems with complicated cutting tools. |
| Learning Outcomes of the Course Unit |
|---|
| Students do one's homework of cutting tool design, master calculations of basic tool surface, cutting geometry control and another parts of tool design. They deepen their knowledge in project there is attached to technological process of tool´s machining and with conditions its service. |
