Abstract

Every manufacturer is looking forward to satisfy all of criteria that its product must have. Means, tools and methods are used to ensure the consistency of product characteristics. One of its important characteristic or feature is geometrical specification or it is better to say Geometrical Product Specifications (GPS) are a means to transform function dependent demands into produced work pieces. This paper introduces the application of analysis of workpiece geometry measurement results regarding the recently developed so-called Skin-Model. This model enables the complete implementation of Geometrical Product Specification and Verification into Co-ordinate Measuring Techniques and vice versa. Selected series of work pieces from industrial manufacturers were measured in the precision measuring laboratory. Based on the measurement results gained it was possible to carry out extensive evaluations by using statistical methods e.g. correlation analysis. As result can be drawn about the correlation between different geometrical deviations and the manufacturing conditions for the achieving lower costs and higher quality in production.
