The problem of processing thin-walled parts is considered. The ribs of such parts undergo significant deformation during machining, which complicates the observance of the specified quality of accuracy. The selection of the correct cutting mode will reduce the deflection of the part so that the dimensions of the finished product will not go beyond the tolerance range. The calculation of the parameters for the cutting mode can be very laborious, which means it is necessary to provide for its automation. The purpose of the study is to develop an algorithm for automating the calculations for cutting modes for thin-walled parts, in which the dimensions of the finished product will be within the tolerance range of a given quality of accuracy. Research methods include the analysis of existing methods for solving the problem, the analysis of the deformations of the part during milling, the search of solutions for the integration of various programs for the automation of calculations. The part was modeled in the ANSYS software package when processing at standard cutting conditions and at softened modes obtained by applying the algorithm. The results show a significant improvement of the parameters of the finished product.
