“…The existence of such surfaces is complicated by the modification of polynomials and NURBS surfaces. NURBS is one of the most popular and successful methods for designing complex surfaces in computer-aided manufacturing [25][26][27][28][29], geometric design (CAD) and computer graphics [30][31][32][33][34][35].…”

Shaped plates with a special shape of texture on the front surface are widely used in the production of products of complex shapes from heat-resistant materials. An important stage of technological preparation for the formation of a system for the automated production of plates using laser ablation is the assignment of recommendations for the shape of the front surface. The technical result is ensured by the rational shape of the front surface of the replaceable multifaceted plate, which meets the requirements of manufacturability and increased performance when using it. Placement on the front surface of a microrelief, which is formed by a set of holes in the form of a group of micro-holes with a radius of 20-40 μm, a depth of 20-40 μm, which ensures the placement and retention of a suspension based on molybdenum disulfide during drilling, and the coordinates of the centers of the holes are determined by new analytical dependencies. This technological solution will significantly increase the speed of writing programs to control machines for laser ablation.

NURBS curve is applied to model and machine of integral impeller to get better smooth streamline in this work. In order to get high precision surface modeling of impeller, complex surface modeling method for impeller is studied through inputting NURBS curves and surfaces obtained by MATLAB into CAXA Manufacturing Engineer, which solves the problem that cannot be designed NURBS curve and surface directly in the CAD software. Grooving and expanding groove tool paths are obtained according to the NURBS curve of top curve and root curve, and it's interpolation step size and the row spacing are determined according to the curvature of the curve and interpolation period. Meanwhile, Five-axis side milling method is used to achieve the vane finish machining, and streamline processing method is adopted to realize the finish machining of the channel. All work is verified in a virtual simulation system of 5MC850-C machining center, and these simulation results show that machining accuracy error of the impeller is between -0.007 mm and 0.012 mm, meeting tolerance range of the impeller design.

Adaptive CNC machining process is one of the efficient processing solution for near- net- shaped blade, this study proposes an adaptive computer numerical control (CNC) machining process optimization scheme based on multi-process machining errors data flow control. The geometric and mechanical models of the multi-process adaptive CNC machining process are firstly constructed. The multi-process machining error data flow and the process system stiffness of near- net- shaped blade are then experimentally explored. The machining error flow collaborative control of the near- net- shaped blade multi-process CNC machining is finally realized by the adaptive CNC machining process under the premise of sufficient stiffness of the blade- fixture system. The results show that the dynamic displacement response of the blade multi-process CNC machining process is controlled within 0.007mm. The optimized adaptive CNC machining process based on the multi-process geometric machining error data flow control and the sufficient stiffness of blade- fixture system can realize the multi-process machining error control and high-precision machining of near- net- shaped blade. The process chain of the optimized adaptive CNC machining process is reduced by 87% compared with the low melting point alloy pouring process and 50% compared with adaptive CNC machining process of the twice on-machine measurement on the blade body.
