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 paper present a practical knowledge-based system, for rotation parts. The core of a CAD system is the, which makes use of graphics for product representation, databases for storing the product model and drives the peripherals for product presentation. The possibility of improvement CAD using the application based on object oriented method paper is shown in this paper. The application is linked to the CAD systems using the API commands. Originally the technique was aiming at automating a number of tasks a designer is performing and in particular the modelling of the product.

ABSTRACT: In this paper will be showed process planning using web design. All elements will represent participation in forming knowledge base for process planning of class rotational parts. CAPP system will show method for representation knowledge using object-oriented programming. Web technolgy will be used for connection between CAPP system and users of technologies. Proposed methodology will use an object-oriented method for the generative process planning in order to shorten the time.

Injection molding is one of the most popular polymer processing methods due to its high production rate as well as its ability to produce very complex geometries at very low cost and within few seconds. In this the paper, optimal injection moulding conditions for minimum shrinkage during moulding are found by technique (Taguchi method). Taguchi method has two main instruments, which are signalto-noise (S/N) ratio and orthogonal arrays. S/N ratios were used for determining the optimum combinations of the process conditions for shrinkage. Finals, optimum levels of the input parameters that minimize shrinkage, for both materials are determined
