“…The movement speed of the contact sensor was set at 0.300 mm.s -1 and the measured and evaluated length was of 4 mm. The method did not pose any risk in terms of plastic deformations, this is something of vital importance in the measuring of surfaces and has been nicely addressed by (20) in their paper. The measured values are shown in Tables 2, 3 and 4 respectively.…”

The present paper discusses the impact of the speed of an abrasive water jet cutting process on some surface properties and morphology of the S235JRG1 steel. The values of the cutting speeds used for the analysis were of 100, 150 and 200 mm.min−1 respectively. A contact profile method was used to analyze the surface roughness during the conducted tests. In this study, the observed surface roughness parameters were the Ra, Rt and Rz, respectively. At the same time, these parameters were measured in three positions, i.e.: at the inlet (A), in the middle (B) and at the exit position (C) of the water jet nozzle with respect to the machined material. The experimental study showed that the roughness of the surface reached higher peaks and was more pronounced at the exit position (C) of the water jet. Similarly, it was also concluded that a better quality of the surface was achieved at a speed of 150 mm.min−1.

“…With the change of the geometric errors, the relative position of slide blocks in the direction of X and Y will be changed, which leads to the deformation and the stress on the test plate [18]- [19]. But the stress was not evenly distributed.…”

The relative positions between the four slide blocks vary with the movement of the table due to the geometric errors of the guide rail. Consequently, the additional load on the slide blocks is increased. A new method of error measurement and identification by using a self-designed stress test plate was presented. BP neural network model was used to establish the mapping between the stress of key measurement points on the test plate and the displacements of slide blocks. By measuring the stress, the relative displacements of slide blocks were obtained, from which the geometric errors of the guide rails were converted. Firstly, the finite element model was built to find the key measurement points of the test plate. Then the BP neural network was trained by using the samples extracted from the finite element model. The stress at the key measurement points were taken as the input and the relative displacements of the slide blocks were taken as the output. Finally, the geometric errors of the two guide rails were obtained according to the measured stress. The results show that the maximum difference between the measured geometric errors and the output of BP neural network was 5 μm. Therefore, the correctness and feasibility of the method were verified.

To promote the engineering application of composite transmission of high speed curve face gear, which consists of a cylindrical gear and a high speed curve face gear, the analysis of tooth bending stress should be taken into consideration. High speed curve face gear pair is a new type of curve face gear pair. Combined with the principle of high speed cam and curve face gear pair transmission, it can transfer the axial/rotation composite motion and power between two intersecting shafts. Based on the gear engagement principle, the gear meshing coordinate system was established and the fundamental of the high speed composite transmission was expounded. Combined with the tooth profile equation of generating gear, the tooth surface equation of high speed curve face gear was gained. Tooth force, contact ratio and normal load distribution were calculated. Then the tooth bending stress of high speed curve face gear during the transmission was calculated and analyzed in detail. Influence of basic parameters on tooth bending stress was discussed. Finally, the simulation and measurement experiment of tooth bending stress was carried out. By the comparison analysis of simulation, experiment and theory, the correctness of tooth bending stress calculation method was verified, which has important guiding significance for the further research of high speed curve face gear of composite transmission.
