NiTi alloy wires are widely used in many applications for examples, orthodontic arch wires, mini screw implant, sensors, etc. Usually, wire drawing process is chosen to produce arch wires because of its high productivity as well as superior surface quality of the drawn wire surface. In the case of NITI arch wire, the cold work occurred during wire drawing operation also plays important role to ...

The traditional teaching mode of mechanical drawing cannot adapt to the needs current applied talents. In order make course serve training talents effectively, it is necessary improve drawing. This paper explores improvement from three aspects content, method and assessment method, so as closer actual engineering, meet enterprises for talents, quality students.

Cold drawing process is one of the most used metals forming processes in industries for forming seamless tubes. This process of plastic deformation of metals occurs below the recrystallization temperature and is generally performed at room temperature. When metal is cold worked, upon the release of forming force, the springback occurs. In this paper, the springback effect of the seamless tube t...

This work explains the development of a novel approach to beautify a face, merging an evolutionary approach and aesthetics graph drawing. The objective of this work is to build a beautify face seen against the input face. The aesthetics graph drawing algorithm works as the mutation operator. The approach of force-directed graph drawing which in turn is the solution to aesthetical graph drawing ...

M. Suliga, R. Kruzel, Czestochowa University of Technology, Czestochowa, Poland In the paper the infl uence of the hydrodynamic die on mechanical properties has been assessed. The drawing process of φ 5,5 mm wires to the fi nal wire of φ 2,5 mm was conducted in 7 passes, in industrial conditions, by means of a modern Koch multi-die drawing machine. The drawing speed in the last passes was 8,2 m...

Abst rac t . Functional parts i.e. mechanical parts with intrinsic functionality such as screws, hinges and gears, are appealing high level entities to be used in line drawing understanding systems. This is because their functionality can be used by a reasoning agent to infer surrounding objects and because they are usually drawn following standards making them easier to be detected. In this ch...

In the present work, forming limit diagrams and strain distribution profile diagrams for extra deep drawing steel at room and elevated temperatures have been determined experimentally by conducting stretch forming experiments by using designed and fabricated warm stretchforming tooling setup. With the help of forming Limit Diagrams (FLDs) and strain, distribution profile diagrams the formabilit...

Optical fibers are crucial in the field of telecommunications, offering the advantages of low loss. broad bandwidth, fine diameter, light weight, freedom from electromagnetic induction, freedom from crosstalk, and efficiency in resource consumption. In comparison to the copper conductors used in conventional telecommunications cables, however, they are at a disadvantage in terms of their low me...

We describe an improved implementation of ANON, a schema-driven image analysis system capable of producing high level interpretations of greyscale images of mechanical engineering drawings. The system has been extended to incorporate a drawing memory into which completed schema instances are placed and which may be accessed as an integral part of ANON's knowledge directed visual search. This me...
