The paper deals with influence of various milling strategies on the accuracy of produced part (circle pocket). One of the most important factors in milling, which influences surface quality is milling strategy. Sample design was created in CAD system Solidworks. Milling tool paths were created in CAM system SolidCAM. Utilization of CAM systems in product design helps to satisfy demands on the quality of produced part from the point of view product accuracy. Surface quality is influenced by several process parameters such as tool diameter, cutting parameters, work-piece material properties, clamping of the part, milling strategy and others. In this article, milling strategies Constant Z, Pocket, Pocket auto borders and Spiral strategy and their influence on surface quality of produced parts were evaluated. In the first step simulations of different toolpaths were conducted. The results obtained from simulations were compared and evaluated. Milling strategies mentioned above were used in experimental production of the parts. Surface quality and deviations (roundness, cylindricity and shape deviations) of produced experimental parts were measured on CMM device. Experimentally measured values were evaluated and analysed.

Keywords: SolidCAM; milling strategies; geometrical characteristics
