The problem of the workpiece shape recognition, and technological process selection and optimization always includes the possibility of shape complexity assessment, and selection of primary process and sequence of operations. The process plans for mechanical products include selection of manufacturing processes: a primary process, and subsequent processes. In the first part, the objective of our research was to investigate the relation between requirements of the design, production quantity and material on one hand and capability of particular process on the other hand in order to be able to consider only the processes that make sense. Also, production costs, quality, lead-times and ecological aspects had to be considered. Our intention was to research and to give some guidance in classifying these requirements, to find a way how to deal with overlapping capabilities of the processes and to explore methods of dealing with numerous data that would facilitate decisions regarding "best" process selection. In the second part, our research explains the procedure for calculating shape complexity. The possibility to express it as an exact value is useful because it enables distinction on the quantitative level. This is needed for research of shape influence on process planning. In the third part, the focus of our research is creation of learning materials for defining the main criteria for selection of primary processes and types of operations in production. The selection of a primary process is based on material nature, quantity, shape complexity, part size and some other factors. Type and sequence of operations are the result of the influence of different factors such as product shape, surface roughness and tolerance. The application enables users to fully understand the procedure of primary process and operation sequence selection through step by step tutorials. The base programming language of E-Lapp application is Visual Basic.Net, the tools used to create e-learning materials are Microsoft PowerPoint 2007 and iSpring Presenter (Adobe Flash).
