This paper presented a toolpath planning and generating method for machining a hub surface of a blisk. This method can be used to generate smooth and gradually changing toolpaths and avoid an undercut on hub. In this paper, the hub surface has been defined with a uθ-parametric region. Then character curves, character points and extension curves have been solved in the uθ-parametric region. These curves have been employed to define boundaries of a machining region on the hub surface. The machining region parted by the boundaries has been mapped into a ws-parametric region which was applied to plan toolpaths. The method was employed to mill the hub surface of a blisk, and the results indicated that the profile error of the hub was within ±0.02mm after machining. This method has a significant value of practical applications, and the machining precision can satisfy the designing requirement of a blisk.

“…This method needs many iterations and the calculation is not simple enough. Xin et al [25][26][27] and Zhang et al 28 proposed a new method to remove the large margin of blisks channel by disc milling cutter instead of ball-end milling cutter or plunge milling cutter. Zhang et al 28 presented a theoretical force model for the milling method, but the cutting force coefficients are difficult to identify.…”

Tool eccentricity has a significant impact on machining quality, accuracy, and operation status of machine tool. It is difficult to accurately identify tool eccentricity. In this paper, the mathematical models of instantaneous undeformed cutting thickness and cutting force considering tool eccentricity are determined by theoretical method. Based on the model, the identification method for eccentricity parameters is proposed, and the eccentricity parameters of disc milling cutter is identified. According to the identified parameters, the cutting force is verified. The results show that most of the values of measured cutting forces are greater than the predicted ones considering tool eccentricity. In the future, it is necessary to establish a new cutting force model considering both tool eccentricity and tool wear.

“…Disc milling operation is used to roughly mill blisk tunnels in previous study. 3 The material removal rate (MRR) of disc milling is high. Experimental results show that the efficiency of disc milling operation is 10 times of side milling and is two times of plunge plus side milling.…”

Blisk is a key component of new aero-engines. To improve machining efficiency, disc milling is used for roughing blisk tunnels. The multi-objective optimization is employed to optimize disc milling process. In this study, an integration-based approach that used grey relational analysis (GRA) coupled with radial basis function (RBF) neural network and particle swarm optimization (PSO) algorithm is applied to solve the optimization problem. To achieve smaller cutting force and greater material removal rate (MRR), the appropriate cutting speed, feed rate per tooth, and cutting height needed to be determined. A hybrid experiment scheme of three factors–five levels is carried out to generate data sample. Results of verified experiments indicate that GRA–RBF–PSO approach can improve performance better than original GRA.
