High Precision Solution of Face Gear Measurement Model based on POS Algorithm
In order to obtain an accurate model for the theoretical measurement of face gear,the paper presents a theoretical measurement model of straight face gear according to the face gear machining principle and the measuring principle of CNC gear measuring center.The improved POS algorithm was used to solve the theoretical measurement model.The results obtained were compared with the ones obtained by using the third-party software,showing that the absolute error is less than 1um.Finally,the face gear measurement model was experimentally verified by using the CNC gear measuring center.The tooth surface error and tooth pitch error of the face gear got measured,verifying the effectiveness of the method.The study also improves the portability of the face gear measurement software system.
