摘要：Large composite revolution parts (as jacket parts) are very important in aerospace engineering, so machining accuracy should be ensured by the technique of on-machine geometric parameters measurement. Then, an on-machine measurement method of the taper value is presented.Firstly, based on a high precision length gauge and a high speed counting-card, X coordinate, Z coordinate and radial error of the part are measured on-machine after processing. Secondly, a taper algorithm is proposed, in which least square and multi-generatrix mean value are used. Finally, the cause of taper error is revealed and all the errors are compensated to the taper value. Experimental results indicate that the taper value measured on the on-machine system agrees fairly well with the measured one on three-coordinate measuring machine, and the effectiveness and practicability of the method are fully verified.
