In the designing of machine tools the absence of a detailed design procedure for selecting friction material on slideways often results in the stick-slip phenomena causing tolerance defects and undesirable motion properties. The paper describes the use of self-organising maps (SOM) to capture the tendencies of the stick-slip phenomena, according to predefined parameters, from experimental data. These tendencies are presented graphically to the designer through which the designer can analyse and predict the stick-slip properties for a given slideway set-up. Due to the intelligent data grouping properties of the SOM the graphical interface produces areas of "acceptable" and "unacceptable" stick-slip properties according to the designer's stick-slip criteria for the current slideway design. The above results in the correct friction material selection and slideway surface finish for a certain stress on the friction material. The system tested in industry proved to be very successful and is currently under further development to include an expert system for more detailed design by various graphical interfaces.
