[0038] Example

[0039] see figure 1 As shown, the circular thin-walled workpiece has 6 round holes evenly distributed on it, and the circular thin-walled workpiece is measured by the OGP optical image measuring instrument as follows:

[0040] 1. Rough construction of workpiece coordinate system

[0041] Select the appropriate magnification in the image window and focus on the inner diameter circle clearly, and measure the inner diameter circle c in the measurement mode 1 , click the inner diameter circle c in the model window 1 , follow the screen prompts to move the lens to the inner diameter circle c 1 The center of the circle, click the start newroutine icon, click the XY coordinate icon to clear it to zero, that is, the center of the inner diameter is the coordinate origin, click the crosshairtarget icon, click the circle icon, and manually measure the inner diameter circle c 1 , any one of the 6 circular holes c 2 , in the construction mode, click the Datum Origin i...

Abstract

The invention provides a method utilizing an OGP optical image measurement instrument for measuring a round thin-wall work piece, relates to a work piece parameter measurement method and aims to solvea problem of thin wall work piece measurement difficulties. The method mainly includes steps of 1, rough establishment of a work piece coordinate system; 2, fine establishment of a work piece coordinate system; 3, work piece measurement; 4, work piece analysis; 5, measurement program preservation; 6, preserved program calling for establishment of connection between the work piece and the machinecoordinate system and said program calling for work piece automatic measurement and analysis. The method provided by the invention is used for measurement of the round thin-wall work piece.

Description

technical field [0001] The invention relates to a method for measuring workpiece parameters, in particular to a method for measuring parameters of circular thin-walled workpieces by using an OGP optical image measuring instrument. Background technique [0002] In the use of OGP optical image measuring instrument, it often encounters the situation of measuring workpieces in batches. Most of the workpieces we measure are circular workpieces, especially circular thin-walled workpieces. The structural feature of this type of workpiece is that round holes or square grooves are uniformly distributed on its circumference. It is necessary to measure and analyze parameters such as the size, angle, concentricity and central diameter of these uniformly distributed holes or grooves. [0003] The original measurement method is: we usually measure each workpiece one by one, and then analyze the corresponding parameters. The method for the optical image measuring instrument to realize th...
