Abstract: A datuming device is provided for use with a machine tool having a movable member which is guided under computer numerical control. The datuming device permits measurement of displacements in a direction not parallel with a displacement probe's line of travel. The device includes a non-sensitive surface which, when probed by the displacement probe, does not indicate a changing displacement when the movable member is moved from a first position to a second position. The nonsensitive surface serves as a reference surface. The device further includes a sensitive surface which, when probed by the displacement probe, exhibits a changing displacement when the movable member is moved from the first position to the second position. The sensitive surface is generally configured as an inclined surface on the datuming device.

Abstract: An edge contouring system for removing burrs from edges of precision parts. The system includes an industrial robot for moving a special piloted deburring tool along the part edges. A compliance device applies a constant force on the deburring tool to keep it in contact with the part edge, yet permits movement of the tool in a direction normal to the part surface to accommodate for irregularities in the part geometry. A pilot integral with the deburring tool limits penetration of the tool into the part edge.
