  • Patent number: 12000094
    Abstract: Rail grinders and related methods of rail grinding in which custom grinding patterns are continually updated based upon an operational status of the rail grinder. The rail grinder includes a plurality of individual grinding modules that are individually arranged to generate the custom grinding patterns for individual rail segments. The custom grinding patterns allow the rail grinder to grind a desired rail profile for each rail segment in a minimum number of grinder passes and at a maximum operating speed for the rail grinder. Utilizing a variety of inputs including current rail conditions, desired rail profile, rail segment type, available grinding modules and grinding module style, a processing system either on-board or remotely located from the rail grinder can iteratively develop a custom grinding pattern that is temporally unique to each rail segment.

  • Patent number: 11945075
    Abstract: A dresser is enabled to adjust a swing speed in scanning areas set on a polishing member along a swing direction. A surface height of the polishing member in monitoring areas set in advance on the polishing member along the swing direction of the dresser is measured. A dress model matrix defined from the monitoring areas, the scanning areas and a dress model is created. Height profile predicted value is calculated using the dress model and the swing speed in each scanning area or a staying time. Evaluation index is set based on a difference from a target value of a height profile of the polishing member and a step of setting the swing speed in each scanning area of the dresser based on the evaluation index. At least one of parameters to determine the target value or the evaluation index of the height profile is made to change automatically.
