      The paper presents an approach for the synthesis, analysis and optimisation of 3-axis machine tool concepts. The machine tool configurations are described by ten configurational parameters. The machine variants are assembled from components having parametric shapes and dimensions. Three analyses are developed for the evaluation of the generated machine variants: (1) a static analysis for calculating the static stiffness; (2) a dynamic analysis for calculating the natural frequencies; (3) and a clearance analysis for checking the geometric interference between the components. The optimisations of the configurational and of the geometrical parameters are carried out by genetic algorithms. The objective functions, i.e. the fitness functions of the genetic algorithms, can be composed from the following: to maximise the static stiffness; and/or to maximise the lowest natural frequency; and/or to minimise the geometric interferences; and/or to minimise the total volume of the machine tool.
