A Hole Diameter Measurement Model on Machine Based on Single Laser Beam Rotation
The hole inner diameter measurement for large precise workpieces is very common on site, and the current measurement methods are inconvenient. A single laser rotation measurement method is presented. Through the analysis of limit distance between a fixed point of the rotary axis and the measuring points with a sensor’s value, a searching model with limiting point can be set up for any surface. The operation method is suitable for measuring workpiece on machine. The hole diameter can be measured by searching the end points in the direction of diameter on the basis of the model and with the comparative measurement combined. The model can be implemented easily because it just needs a rotating spindle without any encoders or other auxiliary parts. The experimental results show that the method is valid. It is of great significance in the integration of machining and measurement for the hole on large workpieces.
