Abstract
A toolholder apparatus includes a head, a cutting tool mounting fixture attached to the head for holding the cutting tool, and a floating roller assembly pivotally mounted relative to the head. These components are arranged and constructed so that during the cutting of a workpiece with the cutting tool the floating roller assembly can pivot about a pivotal axis relative to the head to allow the floating roller assembly to align with the workpiece. A mechanism is also provided for accomplishing the initial adjustment of alignment of the cutting tool with the rotating workpiece. This mechanism includes a cylindrical shaft extending from the head, and having an eccentric cam follower lug extending transversely from the shaft. A mounting block has a cylindrical bore disposed therethrough, and the shaft is received through the bore of the mounting block. A cam piece is slideably disposed within the mounting block to rotate the shaft as the cam piece slides relative to the mounting block. An adjuster is provided for moving the cam piece relative to the mounting block. Methods are also provided for machining an elongated rotating workpiece utilizing the apparatus described.
