The paper presents the results of the investigations on the direction-dependent accuracy of the point identification during contact probe measurements with a coordinate measuring machine (CMM). Considering the contact point identified by an orthogonal to the surface probe movement, the transformation of coordinates was made in order to calculate the displacement of the measured point. As a result, the positioning accuracy was estimated in three axes. The experiments demonstrated a strong dependence of the displacement on the declination angle. Moreover, it was found that the directional surface texture which provided different roughness in perpendicular directions, had an impact on the positioning accuracy.

Intelligent production of small modulus powder metallurgy gearing requires rapid and accurate measurement to ensure product quality. Currently, the contact measurement method exemplified by gear measuring centers lack efficiency and require gear mounting reference, which prevent them from meeting the requirements for on-line inspection of small modulus gears. Therefore, an optical method of gears was intensively researched. It combined the advantages of laser and vision inspection, which meet the requirements for accuracy and efficiency in on-line inspection. Based on the measurement principle of the line laser sensor and vision camera, a model of the measurement system was established; a standard block was designed to calibrate the system. The surface data of tooth flank were acquired by laser scanning and evaluated to analyze the accuracy. The result of method was validated by comparison with the gear measurement center. Both are of good agreement. Sufficient experiments verify the feasibility of proposed method for on-line inspection.

On-machine inspection has a significant impact on improving high-precision and efficient machining of sculptured surfaces. Due to the lack of machining information and the inability to adapt the parameters to the dynamic cutting conditions, theoretical modeling of profile inspection usually leads to insufficient adaptation, which causes inaccuracy problems. To address the above issues, a novel coupled model for profile inspection is proposed by combining the theoretical model and the data-driven model. The key process is to first realize local feature extraction based on the acquired vibration signals. The hybrid sampling model, which fuses geometric feature terms and time-frequency domain feature terms, is modeled by the lever principle. Then, the weights of each feature term are adaptively assigned by a multi-objective multi-verse optimizer. Finally, an inspection error compensation model based on the attention mechanism considering different probe postures is proposed to reduce the impact of pre-travel and radius errors on inspection accuracy. The anisotropy of the probe system error and its influence mechanism on the inspection accuracy are analyzed quantitatively and qualitatively. Compared with the previous models, the proposed hybrid profile inspection model can significantly improve the accuracy and efficiency of on-machine sampling. The proposed compensation model is able to correct the inspection error with better accuracy. Simulations and experiments show the feasibility and validity of the proposed method. The proposed model and corresponding new findings contribute to high-precision and efficient on-machine inspection, and help to understand the coupling mechanism of inspection errors.
