  • Method and apparatus for detection of drill bit wear
    Patent number: 8899350
    Abstract: A method for determining wear of a drill bit is disclosed. The method includes drilling a first hole in a worksite based on a hole pattern having a plurality of planned holes and determining an energy required to drill the first hole. The method also includes drilling a second hole in the worksite and determining an energy required to drill the second hole. The method further includes determining a wear of the drill bit using the determined energy required to drill the first hole and the determined energy required to drill the second hole.
    Type: Grant
    Filed: October 21, 2011
    Date of Patent: December 2, 2014
    Assignee: Caterpillar Inc.
    Inventor: Frederic Nadeau
  • Sequencing algorithm for planned drill holes
    Patent number: 8733473
    Abstract: A method for sequencing drill holes for a mobile drill rig is disclosed. The method may include receiving a hole pattern having a plurality of planned holes and generating at least a first group of parallel pathways and a second group of parallel pathways between the plurality of holes of the hole pattern. The first group of pathways may be angled relative to the second group of pathways. The method may also include selecting between the first group of pathways and the second group of pathways based on which group of pathways includes fewer total pathways.
