Abstract:
1. A method comprising the steps of: disposing a coolant nozzle having a base and a distal end for movement relative to a grinding wheel and to a work-piece including movement of the distal end in a first plane normal to an axis of the grinding wheel along a first arcuate path centered on a pivot axis at the base and also movement of the pivot axis in the first plane along an orbit centered on the grinding wheel axis; selecting a position of the distal end along the first arcuate path; projecting a second arcuate path in the first plane centered on the grinding wheel axis and having a radius extending to the position of the distal end along the first arcuate path; generating a third arcuate path in the first plane corresponding to a location of the work-piece that would be contacted first by the distal end during movement along the second arcuate path; and limiting movement of the distal end along the second arcuate path by an intersection between the second arcuate path and the third arcuate path.
