| Abstract: | The special geometrical contour of a piston is a ellipse in cross section and a convex curve in axial section. The principle and method for measuring piston contour are discussed in this paper. For improving the measurement accuracy, a new technique is developed to correct the instrument errors in a revolving axle system with ussual manufacturing accuracy. Testing results by a sample instrument for piston test shown that the standard error is 1. 8 um for the measurements without error correction technigue, and the standard error is 0. 6 um for the measurements with error correction technique. |
