These errors should be taken into account in the process of the develop of the control programs in the CAM package for operations that are performed on CNC machines. The following tasks were set: a) to reduce of the height of the combs to the permissible value (0,01\u20260,02 mm) by selecting of the tool diameter, interlacing and machining strategy; b) to study the peculiarities of the forming of the approximation\u2019s error of matrices\u2019 3D models, depending on the shape and the size of the model, and to develop recommendations for the reducing them to acceptable values.

\nError formation was studied using 3D models with dimensions up to L\u00d7B\u00d7H=500\u00d7500\u00d7500 mm. Dependences of the height of the combs on the milling step were obtained when machining the horizontal plane for the different diameters of a spherical mill. The influence of the inclination angle of the machined plane and the milling step for a spherical milling cutter \u00c610 mm on the height of the combs was studied. Recommendations for the choice of milling strategies with constant and variable milling step have been developed.
\nTriangulated surface models were created by the translation of the solid 3D models of typical matrix elements from the CAD program that uses Parasolid kernel into stl format. The marginal error values for the approximation of 3D models in the form of a parallelepiped, cylinder, sphere, and torus with different aspect ratios by X, Y and Z coordinates are presented in the tables.
\nAccording to the results of the research, recommendations were obtained for the development of control programs for finishing milling of molding surfaces of small- (up to 100 mm) and large-sized die molds.
