Paper presents some investigation concerning FEM simulation analysis and optimization of turning process of the engine block surface. During machining of the workpiece with thin-walled parts, the important role plays the value levels of the components of resultant cutting force. Cutting parts are oriented concentrically and they are in a small distance from each other, which causes difficult access for cutting tools. To conduct the feed speed optimization process a force model was built which enabled to calculate cutting forces values depending on the cutting parameters (feed speed in our case). Changes of the feed value were possible under the condition that its increase does not cause excessive cutting resistance which can influence the geometry deformation of the machined block. After application of the simulation and optimization procedure an increase of efficiency was achieved.
