This article presents architecture of integrated intelligent computer-aided design system for designing mechanical power-transmitting mechanisms (IICADkmps). The system has been developed in C# program environment with the aim of automatising the design process. This article presents a modern, automated approach to design. Developed kmps modules for calculation of geometrical and design characteristics of mechanical power-transmitting mechanisms are described. Three-dimensional geometrical parameter modelling of mechanical power-transmitting mechanisms was performed in the computer-aided design/computer-aided manufacturing/computer-aided engineering system CATIA V5. The connection between kmps calculation modules and CATIA V5 modelling system was established through initial three-dimensional models – templates. The outputs from the developed IICADkmps system generated final three-dimensional virtual models of mechanical power-transmitting mechanisms. Testing of the developed IICADkmps system was performed on friction, belt, cogged (spur and bevel gears) and chain transmitting mechanisms. Also, connection of the developed IICADkmps system with a device for rapid prototyping and computer numerical control machines was made for the purpose of additional testing and verification of practical use. Physical prototypes of designed characteristic elements of mechanical power-transmitting mechanisms were manufactured. The selected test three-dimensional virtual prototypes, obtained as an output from the developed IICADkmps system, were manufactured on the device for rapid prototyping (three-dimensional colour printer Spectrum Z510) and computer numerical control machines. Finally, at the end of the article, conclusions and suggested possible directions of further research, based on theoretical and practical research results, are presented.

This article presents evidence of the convenience of implementing the geometric places of the plane into commercial computer-aided design (CAD) software as auxiliary tools in the computer-aided sketching process. Additionally, the research considers the possibility of adding several intuitive spatial geometric places to improve the efficiency of the three-dimensional geometric design. For demonstrative purposes, four examples are presented. A two-dimensional figure positioned on the flat face of an object shows the significant improvement over tools currently available in commercial CAD software, both vector and parametric: it is more intuitive and does not require the designer to execute as many operations. Two more complex three-dimensional examples are presented to show how the use of spatial geometric places, implemented as CAD software functions, would be an effective and highly intuitive tool. Using these functions produces auxiliary curved surfaces with points whose notable features are a significant innovation. A final example provided solves a geometric place problem using own software designed for this purpose. The proposal to incorporate geometric places into CAD software would lead to a significant improvement in the field of computational geometry. Consequently, the incorporation of geometric places into CAD software could increase technical-design productivity by eliminating some intermediate operations, such as symmetry, among others, and improving the geometry training of less skilled users.

Rapid Prototyping (RP) can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional Computer Aided Design (CAD) data. What is commonly considered to be the first Rapid Prototyping technique, Stereolithography was developed by 3D Systems of Valencia, CA, USA. The company was founded in 1986, and since then, a number of different Rapid Prototyping techniques have become available. In paper are presented possibilities of Rapid Prototyping application in area of intelligent optimization design.

In recent years, rapid prototyping (RP) technology has been implemented in many spheres of industry, particularly in the area of new product development. Rapid prototyping has the capability to produce a tangible solid part, directly from three-dimensional computer aided design (CAD) data, from a range of materials such as photocurable resin, ceramic and metallic powders and paper. However, in most cases, models built in acrylic-based resin in the stereolithography (SL) process have not yielded the desired quality, which has led to a shift in the use of this resin to more expensive ones that have longer build time. An experimental investigation has been carried out to determine statistically the optimum build parameters with the use of the Taguchi method in order to improve the SL product quality. Two new hatch styles have been developed in this study and a confirmation experiment has shown a significant improvement in part accuracy.

A VLCC (very large crude oil carrier) has approximately 1000 curved longitudinal beams, many of which have three-dimensional complicated curvatures. Due to the shortage of highly skilled workers and the need to keep costs down, production and structural designers have worked to reduce the number of such beams. In order to meet the requirements of production, the authors' company has attempted several design approaches for the longitudinal beam layout to reduce the number of beams that have complicated curvature. Recently, through the application of a computer-aided design system, which has been improved for shipbuilding based on the Calma's system, a new design method for the longitudinal beam layout has been successfully developed. A significant number of beams with a twisted configuration have been eliminated and replaced with beams of simpler, two-dimensional shapes. This paper shows the transition of these design approaches, and the application of the new design to building a VLCC.

This article highlights the striking facts about rapid prototyping; a process that fabricates physical objects directly from computer-aided design sources. The use of rapid prototyping as a replacement for injection molding is still the overwhelming exception and may always be limited to a very narrow niche. Three-dimensional printing has also seen the introduction of materials that improve the durability and appearance of conceptual prototype parts. Z Corp. of Burlington is incorporating new pigments into its binders for its starch- and plaster-based materials. The pigments result in truer and brighter colors and replace the dyes that were previously incorporated into the liquid binders. The company has recently introduced a urethane infiltrant that increases part strength significantly and allows parts with delicate geometries to be.
