This paper deals with technological conditions that are achieved during multi-axis milling operations. The work is focused on the improvement of quality and productivity of machining of complex shape parts. The importance of feed-rate analysis during multi-axis machining operations is mentioned. A postprocessor algorithm for correction of relative feed-rate during multiaxis machining operations has been proposed. The postprocessor generates corrected feed-rate for each block of an NC program when a multi-axis interpolation is found. Thanks to this new postprocessor algorithm, better conditions are achieved during multi-axis machining operations and also a shorter time for NC program execution when it is used without the Tool Center Point transformation. Practical benefits and the functionality of the postprocessor algorithm have been tested by machining the blade containing multi-axis tool paths.
