Abstract
In order to improve the precision and efficiency of the roundness measurement for ring parts
(Diameter 100 – 400 mm; Ring gear, signal ring gear, or inertia ring), this paper designs a Ring
Measuring Tasks Grouping Method (RMTGM), and an Automatic Roundness Measuring System
(ARMS) based on line scan CCD. According to needs analysis, RMTGM finds out how many ARMS
are need and working parameters of them, then groups the tasks. Mechanical vibration is filtrated
and the image data is collected, then, edge information and polar coordinates are calculated. ARMS
computes the roundness of ring parts for quality judgment according to coordinate and least-
squares fitting. Theoretical analysis and practical application results shows that tasks of ring parts
roundness measuring would be well done by ARMS and RMTGM; roundness measured by ARMS is
accurate to ±0.01 mm.
