Abstract: A method of online coaxality error measuring for rotary parts was introduced. The collection of nontouching high precision mesuring point with the application of laseroptical displacement sensors. Both the placement of the sensors and the whole measuring project were presented, and the algorithm for coaxality error based on them was introduced. The result of experiment illustrates that the whole system precision arrives 0.02 mm.
Key words: laser displacement sensor; coaxality error measuring; nontouching
