Abstract: Expanding markets and flexible commercial structures (e-commerce) generate various logistic demands and force manufacturers to offer diverse material handling equipment. To fulfill this demands specially the design process must be straight forwarded to minimize developing time, as most of the whole costs to produce a new product are settled here. Automated storage/retrieval systems (AS/RS) are backbones of many distribution centers and widespread. As they have lots of common attributes and nearly equal characteristics, they are predestinated for knowledge based techniques. The paper now describes knowledge based engineering in general and its additional value and focuses on a practical design of an AS/RS. The main describing equations are derived and the realization in ProEngineer is presented.

Abstract:
This
paper makes a revision of the actual stage in modelling of cutting
processes with bibliographic examples starting from analytical to
orthogonal and ending with dynamic and genetic models. The authors make
also a brief description of the history of the finite element analysis,
a description of the finite element model formulations and give examples
of 2D and 3D FEM simulation of machining processes.
Key
words:
cutting process, milling, cutting model, FEM, orthogonal, 3D model.

Abstract:
The
paper highlights the main mechanisms created inter-organizational
innovation applied to management and research of enterprise. The authors
make a comparative analysis between the situation at European and
national, that of Romania, in terms of inter-organizational innovation.
In the paper are highlighted key concepts which required
inter-organizational innovation at European level as: sharing knowledge,
strategic alliances, strategic entrepreneurship, and innovation
projects. The work proposes resize the concept of innovation related to
efficient management and sustainable development. Resizing is based on
comparative analysis of motivational factors. This analysis provides
resources and supports necessary to support creativity and
inter-organizational innovation such as systems to strengthen their
capacity to create. Strengthening the capacity to create is a way out of
economic and financial crisis. Key words: inter-organizational innovation, comparative analysis.

Abstract: In this paper, there are suggested solutions for profiling the disc tool reciprocal enwrapped to a helical cylindrical surface, with constant pitch. A graphical method has been developed in CATIA environment together with an analytical one, on the base of the helical motion decomposition theorem. There are presented solutions for the disc tool axial section in both analytical and graphical form. There are also included numerical examples concerning the same surface, in order to prove the quality of the graphical method when it is used in profiling disc tools, which generate through enveloping.
Key words: disc-tool profiling, CAD method, analytical method, helical cylindrical surface, helical motion decomposition.
