Abstract
With the continuous improvement of machining precision requirements in modern manufacturing industry, laser displacement sensor is widely used in the field of precision machining measurement with its advantages of non-contact, high precision and fast response. The purpose of this study is to deeply analyze the measurement accuracy of laser displacement sensor in precision machining, and explore the key factors affecting the measurement accuracy by combining theoretical analysis and experimental verification. Firstly, a mathematical model is established based on the optical principle, analyzing the influence of spot shape and surface reflection characteristics on the measurement results; then build an experimental platform and select specimens with different materials and surface roughness for measurement experiments, and obtaining a large amount of data. The results show that the surface characteristics of the materials, especially for high or low reflectivity materials, the measurement error is relatively large; the error can be effectively reduced by optimizing the sensor parameters.
