32-33 STUDIU PRIVIND DEZVOLTAREA ÎN REŢEA A UNUI PRODUS NOU ÎN DOMENIUL SCULELOR AŞCHIETOARE

STUDY ON DEVELOPING IN NETWORK OF A NEW PRODUCT IN CUTTING TOOLS FIELD

 

This study describes patterns of a flexible working structure that allow researchers to react quickly to the environment, to move towards the market, to meet the needs of citizens, to assimilate and process new information in a timely manner, to be innovative and find new solutions. Designing and running a project from an idea, theme, until the prototype imposes complex requirements of the project team in general and project director/project manager – in particular.

 

Keywords: cutting tool, product

31-30 STUDIU PRIVIND ÎMBUNĂTĂȚIREA ACTIVITĂȚII UNUI CENTRU DE CERCETARE

STUDY ON IMPROVING THE ACTIVITY OF

A RESEARCH CENTRE

 

The study started from anticipating and identifying changes related to the research center, defining strategic objectives and building both imaging research center, its work and relations with partners/ customers. The novelty developed in this study is to address three successive analytical methods and the use of two software MACTOR (Méthode ACTeurs, Objectifs, Rapports de force) and Micmac.

30-23 MODELAREA CONSTRUCŢIEI SCULELOR AŞCHIETOARE CU PLĂCUŢE SCHIMBABILE

MODELING THE CONSTRUCTION OF CUTTING
TOOLS WITH EXCHANGEABLE INSERTS
This paper makes improvements in the classical cycle of the research
and development for the new tools, by including simulation, structured
according to the following three steps: modeling the tool, reading the results on
virtual tests and choosing the optimum design. We exemplified the first step by
modeling the construction of a boring tool with twin special tangential inserts,
mounted directly on the tool’s cylindrical body, having a Ф116mm processing
diameter.
Keywords: modeling, cutting tools, exchangeable inserts, simulation,
variables, constraints, optimization, virtual

30-22 CONTRIBUŢII PRIVIND PARTEA ACTIVĂ A LĂRGITOARELOR CU PLĂCUŢE TANGENŢIALE

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.
Keywords: boring tools, tangential inserts, forms, cutting edge,
clearance angle, rake angle, chips
Cuvinte cheie: lărgitoare, plăcuţe tangenţiale, forme, tăiş, unghi de
aşezare, unghi de degajare, aşchii
