UNIFORMITY CORRECTION USING PROGRESSIVE ABLATION

摘要

Systems and methods for determining one or more ablation patterns for selectively removing material from tire bead locations to correct for non-uniformity characteristics, such as lateral force variation, of a cured tire are provided. An ablation order can be determined for a plurality of tracks along a bead of a tire based on sensitivity data associated with the plurality of tracks. One or more ablation patterns can be progressively determined according to a progression scheme defined by the ablation order. The progressive determination of ablation patterns can reduce the computational resources required for calculating the one or more ablation patterns and, in some cases, can reduce ablation time and total ablation for the tire. Moreover, the progressive determination of ablation patterns can provide for the correction of lateral force variation for both clockwise and counterclockwise rotation of the tire.
