Abstract

Rapid prototype is also known as additive manufacturing or 3d printing. Construction of the part or assemble is usually done using rapid prototype technology. With the use of this technology creating and printing the functional end usable parts is directly done from our office, home, collage or any other place with the help of computer and 3D printing machine. The use of rapid prototype technique is becoming more popular in mechanical industries, ornaments and jewelers making industries, medical, educational institutes, fashion industries, food industries, for creation of new models and for many other purposes. This project deals with design, analysis and manufacturing of prototype of complex virtually unlimited internal and external geometry of planetary gear wheel which is used in clock mechanism by using the technology of rapid prototype. To design the model of the prototype CATIA is used where CATIA stands for Computer Aided Three-dimensional Interactive Application. It is the most powerful and widely used CAD (computer aided design) software of its kind in the world. CATIA plays a major role in the design process. In mechanical engineering CATIA enables the creation of 3D parts, from 3D sketches, sheet metal, composites, and molded, forged or tooling parts up to the definition of mechanical assemblies. The software provides advanced technologies for mechanical surfacing. CATIA offers a solution to shape design, styling, surfacing workflow and visualization to create, modify, and validate complex innovative shapes. CATIA supports multiple stages of product design whether started from scratch or from 2D sketches. Here to design the gear consideration of input parameters such as number of gear’s teeth, Gear diameter are taken and then it is modeled. After modeling is done then analysis is done using ANSIS software. ANSYS is a general purpose software, used to simulate interactions of all disciplines of physics, structural, vibration, fluid dynamics, heat transfer and electromagnetic for engineers. So ANSYS, which enables to simulate tests or working conditions, enables to test in virtual environment before manufacturing prototypes of products. Furthermore, determining and improving weak points, computing life and foreseeing probable problems are possible by 3D simulations in virtual environment. ANSYS can import CAD data and also enables to build geometry with its "preprocessing" abilities. Similarly in the same preprocessor, finite element model which is required for computation is generated. After defining loadings and carrying out analyses, results can be viewed as numerical and graphical. ANSYS can carry out advanced engineering analyses quickly, safely and practically by its variety of contact algorithms, time based loading features and nonlinear material models. To analysis the model which is designed by using CATIA need some input parameters like angular velocity, moment etc. Finally after these processes manufacturing of model of planetary gear is done using 3D printing machine with the help of rapid prototype techniques.
