“…This approach is a bit similar to principal component analysis (PCA), but the advantage of PLSR is that both independent variable and dependent variables are used in the process, not just for independent variables. The specific theory of partial least squares regression can refer to literature [19][20][21][22][23][24][25][26][27][28].…”

The thermal error of high-precision computer numerical control (CNC) form grinding machine has become the critical factor affecting its locating precision. Because the thermal error is more complicated to be measured directly, most of the measurement tests are usually aimed at no-load conditions. In this article, a method to evaluate the machine tool thermal error based on the principle of tooth profile error through the gear grinding precision is presented. Based on high-precision CNC form grinding machine need to maintain isoperibol, this paper proposed the ambient temperature as a variable, for different ambient temperature to measure the thermal error of the machine tool. According to the measurement results of the thermal error, the method of partial least squares neural network is used to structure the thermal error prediction model of the machine tool. The experimental data show that the grade of the gear precision can reach four levels at different temperatures. This approach shows a promising prospect in the application of high-precision CNC gear form grinding machine in the future.

Abstract-A method is presented for the optimization of design and manufacture of spiral bevel, hypoid, and worm gears. The aim of the optimization is to improve the operating characteristics of the gear pair, namely, to increase the service life of gears and to reduce the dynamic effects of gear mesh. Optimal modifications are introduced into the tooth surfaces to simultaneously reduce the maximum tooth contact pressure and transmission errors. These modifications are introduced by applying optimal machine tool settings and geometry of cutting tool in the manufacturing process. The method is demonstrated on spiral bevel, hypoid, and worm gears. The obtained results have shown that significant improvements in the operating characteristics of the gear pairs are achieved.

“…Tooth surface modification is an effective method to improve the load meshing performance of the gear pair [1][2][3][4][5], which can avoid edge contact and stress concentration during the working of the gear pair. In the research on tooth surface modification with curved tool profile or multi-segment tool profile instead of straight tool profile, some scholars have done some research on the spiral bevel gears with tapered tooth depth machined by the five-cut method [6][7][8][9] and the spiral bevel gears with uniform tooth depth machined by the hobbing method [10][11]. In addition, there are related studies on optimizing the geometric parameters of the tool profile to improve the meshing performance of the spiral bevel gear pair with uniform tooth depth [12][13][14][15].…”

For the hypoid gear pair of the heavy-duty vehicle drive axle machined by the duplex helical method, in order to avoid edge contact and stress concentration on the tooth surface, a four-segment tool profile is designed to modify the concave and convex surfaces simultaneously. First, the geometric model of the four-segment tool profile is established. Second, the mathematical model of the duplex helical method based on the four-segment tool profile is established, and the method of solving the tooth surface generated by the connecting points of the four-segment tool profile is given. Finally, the finite element method of loaded tooth contact analysis is used to analyze the meshing performance of the gear pair obtained by the four-segment tool profile modification, and the results are compared with the original gear pair. The results show that after the tooth surfaces are modified, the edge contact of the tooth surfaces are avoided, the stress distribution of the tooth surfaces are improved, the maximum contact stress of the tooth surfaces are reduced, and the fatigue and wear life of the tooth surface are improved.
