ASPECTS REGARDING THE ACTIVE PART OF BORING
TOOLS WITH TANGENTIAL INSERTS
The paper presents the main elements of the active part of boring
tools equipped with replaceable tangential inserts. Placing tangential insets of
different types of tools (cutters, boring tools etc.) is designed to reduce certain
aspects of their stress, such as the surface roughness. A short presentation of
the components of tangential insert place on the front of the boring tool is
followed by an analysis of the embodiments of the active part, in terms of
shape, inserts position and of cutting elements (faces, edges, vertices, angles).
At the end of the papers, it is proposed an original form for tangential inserts
used for the boring tool.
