machining operation is one of the most applicable processes for the manufacturing of industrial parts. usually, the quality of finished part in turning operation is measured in terms of surface roughness. in turn, surface quality is determined by machining parameters and tool geometry specifications. the main objective of this study is to model and optimize machining parameters and tool geometr...
in this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. the models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. from the results, the amount of heat generation is directly proportional to the number of edges in the pi...
We define a 3D variant of turtle graphics and present the theoretical foundations of 3D turtle geometry. This theory enables one to reason about open and closed 3D polygonal paths by means of algebraic calculations. In particular, we introduce several equivalence relations on turtle programs and theorems that define corresponding standard forms. We also express the relationship between the symm...
With the trend towards miniaturization, micromachining becomes more and more important in fabricating micro parts. Investigations have shown that unpredictable tool life and premature tool failure present a serious concern in micromachining. To further develop the process, a systematic study of various types of tool geometry has been carried out. The tool failure modes and the ways in which too...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...

The study group aims to support research in computational geometry in structural engineering by bringing expert researchers and practitioners together in order to increase and share knowledge. Research themes relate to digital design and the description of structural geometry based on computational methods and techniques. The use of computational methods and software tools in the creation of st...
