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.

Rapid prototyping (RP) advancements are in light of the rule of making three-dimensional geometries straightforwardly from computer aided design (CAD) by stacking two-dimensional profiles on top of one another. Rapid manufacturing (RM) is the utilization of rapid prototyping advancements to make end-utilize or completed items. Aside from the ordinary assembling methods which are utilized for quite a while assembling of an item, added substance assembling methodologies have picked up force in the late years. The explanation for this is that these techniques don't oblige extraordinary tooling and don't evacuate material which is exceptionally advantageous really taking shape of a segment. Rapid manufacturing is the developing innovation in assembling commercial ventures with a specific end goal to create the model inside the less time and expense effective. In this paper we talked about a portion of the fast assembling advancements in light of the sort of crude material is utilized for the procedures, applications, preferences and limits.

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.

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.

The determination of workspace is an essential step in the development of parallel manipulators. By extending the virtual-chain (VC) approach to the type synthesis of parallel manipulators, this technical brief proposes a VC approach to the workspace analysis of parallel manipulators. This method is first outlined before being illustrated by the production of a three-dimensional (3D) computer-aided-design (CAD) model of a 3-RPS parallel manipulator and evaluating it for the workspace of the manipulator. Here, R, P and S denote revolute, prismatic and spherical joints respectively. The VC represents the motion capability of moving platform of a manipulator and is shown to be very useful in the production of a graphical representation of the workspace. Using this approach, the link interferences and certain transmission indices can be easily taken into consideration in determining the workspace of a parallel manipulator.
