Abstract
Key characteristics of state-of-the-art CNC cutting machine tools – precision, rigidity, productivity are increasing permanently, while in major of cases they are not using accordingly. Reason of so called ravine is in implementation of non up-to-date approaches of process planning and calculation of process related parameters.
Paper describes Adaptive Part Programming (APP) approach which enables to carry out selection of parametrical optimization rules and calculation of tool path geometry directly on CNC machines according to actual values of workpiece parameters. Flexibility of optimization rules selection and possibility to calculate automatically tool path geometry for the each workpiece enlarges range of compensation of disturbances of traditional adaptive control systems with one, “unchangeable” rule. Thus, implementation of APP with existing adaptive control systems makes possible implementation of cheap workpieces with considerable dispersion of hardness and geometry without arising the complexity of manufacturing processes and cost by using the advanced possibilities of CNC machine
tools.
