ABSTRACT:
Both a device and method for adjusting the position of a cutting insert relative to the body of a cutting tool such as a milling cutter are provided. The device includes a cantilevered wall integrally connected to the tool body, that forms a portion of the pocket in the tool body that supports a side of the insert, and a wedge mechanism for elastically flexing the cantilevered wall to adjust the position of a cutting edge of the insert relative to the tool body. The wedge mechanism may take the form of a screw threadedly engaged to the tool body that has a conical head engaged against the cantilevered wall such that when the screw is turned, the conical wedge formed by the screw head flexes the cantilevered wall a small distance. The device advantageously allows fine adjustments to be made in the position of the cutting edge of an insert by the simple turning of a single screw. The method of the invention advantageously allows the adjusting device to be easily installed in conventional cutting tools having preexisting, insert-receiving pockets.
