1. A method of milling grooves in a work-piece comprising:
providing an abrasive fluidjet device that selectively emits an abrasive fluidjet from the device; and
traversing the abrasive fluidjet across a work-piece to form a groove having a selected depth and wall taper in the work-piece, including executing one or more passes along a selected path for the groove with the abrasive fluidjet oriented at a negative lateral angle, executing one or more passes along the selected path with the abrasive fluidjet oriented at a positive lateral angle, and executing one or more passes along the selected path with the abrasive fluidjet oriented at a zero lateral angle.
