Abstract
In the area of automation of process design and stamping objects there are a great number of commercial software products. Each of them has the tools and features aimed at reducing the complexity and accelerating the design time. The article presents classification of the set of domestic and foreign computer-aided design facilities for multiposition stamping objects and processes (CAD MS). The analyzed CAD systems are described by a number of functional features. Using the method of principal components of factor analysis the authors conduct the search of correlations between the features to reduce their numbers. There are five factors (groups of characteristics of CAD MS). The selected factors are given specific names according to the description of their constituent features. The article describes a structural and logical CAD MS framework for the obtained factors. The percentage of computer-aided systems in each factor is presented. For the construction and classification of certain types of CAD MS the authors use k-medium method of cluster analysis. The number of clusters (CAD model) and their volume is defined. These clusters are the best description of a typical CAD MS. The clusters are given the names, and their functionality is described. The defined clusters and their descriptions are coordinated with heuristic division of CAD according to technological and design features. The largest number of CAD MS from the submitted sample refers to technological clusters. Cluster analysis of the large number of CAD shows that the development of design automation of stamping objects and processes is connected with optimization of the sheet stamping technological process and the use of tools and modules of CAE, as well as the development of libraries of standard parts and assemblies subject to knowledge bases.
