Tolerance Based Assembly of Mechanical Joints using Visual Basic
The goal of this project is to performing assembly of mechanical joints based on tolerance. To obtain the proper functioning at the product the tolerance are important role. In this project the assembly of the component based on it tolerance. The required type of fit information gathered through form. This project is to reduce the time taken for assembly process while manual assembly, to improve the best assembly sequence. In this project to do the assembly of machine elements and its dimension with tolerance values are tabulated while reading the component through VB, and database to be created with the available components. Depends upon the user requirement or the application the appropriate components are identified and assembled in the modelling software. A mechanical assembly is a composition of interrelated parts. Assembly data base stores the geometric models of individual parts, the spatial positions and orientations of the parts in the assembly, and the relationships between parts. The manual assembly is a sophisticated tasks which consume time and requires skilled labour and cost. The work employs Visual Basic, SolidWorks and Excel to develop a database management system for standard components. The secondary development of SolidWorks has been performed by Visual Basic and the system is interconnected with SolidWorks. The outcomes were creating a application form to create a tolerance based assembly application which results in increase in speed of part assembly saving time and cost.

IMPLEMENTATION OF HEURISTIC REASONING TO RECOGNIZE ORTHOGONAL AND NON-ORTHOGONAL INNER LOOP FEATURES FROM BOUNDARY REPRESENTATION (B-REPS) PARTS
B-Reps models are represented as complicated network of topology and geometry that will pose difficulties in the recognition of features. To simplify the search process, heuristic reasoning is adopted. Reasoning on topology will search and define the features, and geometry data are then used to extract the geometrical properties. This search process will identify features emanated from inner loops that lead to the recognition of island, pocket, and through pocket. Since the search is mainly based on the topology, the orthogonal and non-orthogonal features can be identified using the same procedure. Then, heuristics reasoning is again applied to features especially nested of pocket and island as well as isolated island to convert the design feature into machining features. Features such as pocket and through pocket and a new feature which is called prismatic ring are identified. The implementation of heuristic reasoning to recognize isolated design features with the aim to recognize machining will simplify the search process on the complicated of B-Reps data. The focus of this paper is to demonstrate the application of heuristics reasoning by showing the programming algorithm based on Visual Basic Language (VBA) using Application Programming Interface (API) of Solidworks CAD software.
