Summary
Subject continues on knowledge, obtained trough technological subjects study
and develops into the deepest knowledge connected with tools construction.
Division of particular lectures is implemented in concordance with methodical
lines and logical sequence (cutting tools materials, cutting tools geometry,
turning tools, tools for holes, draw-through and extruding tools, milling
cutters and milling cutter heads, thread tools, tools for spur gears, module
tools for NC machine tools and centres) from the simpler tools to more
developed tools. In each chapter are named new progressive construction of
tools, attention is paid to their use, servicing and requirements which are
posed on their quality increase. Through study of subject „TOOLS“ students
will familiarize their selves with basic problems concerning cutting tools
drafting, status quo and developing tendencies in this area.
