Abstract Due to the limit of the structural characteristics of piston cylinder for the measuring instrument, a measuring method for the inner diameter of the piston cylinder with three coordinate measuring machine was proposed. Taking the piston cylinders with nominal inner diameters of 19mm, 45mm, and 140mm as examples,the measurements for the inner diameter,external diameter and thickness of the piston cylinder were carried out. The difference of the inner diameter of the piston cylinder obtained with different measurement methods was analyzed and compared, and the reliability of the three coordinate measuring machine for measuring the inner diameter of the piston cylinder was verified. In addition, the influence of the shape characteristics of the piston cylinder on the uncertainty of its inner diameter measurement was analyzed. The measurement results of the inner diameter of the piston cylinder is 18.999mm, 44.983mm, 139.975mm respectively, and the relative measurement uncertainty is 0.016. %, 0.015%, 0.010%.
