Filed:

Aug 6, 2002

Appl. No.:

10/212277

Inventors:

James R. Brock - Rochester Hills MI, US
James J. Robinson - Rochester Hills MI, US

Assignee:

Velenite Inc. - Madison Heights MI

International Classification:

B23B 29034

US Classification:

408154, 408156, 408158

Abstract:

A rotatable cutting tool has a shank portion for coupling to a tool driving device and a cutting portion to which is attached at least one support member for retention of a replaceable cutting element. The support member is so arranged to permit displacement of at least the portion thereof retaining the cutting element whereby the position of the cutting element relative to the body of the cutting tool may be changed by such displacement. A totally enclosed hydraulic force multiplier is mounted within an internal cavity of the cutting tool. The force multiplier is responsive to a control force to effect the displacement of the support member, the control force advantageously supplied by application of pneumatic pressure.

International Classification:

G01B 512

US Classification:

33542

Abstract:

Apparatus for forming and measuring a bore includes a rotating shaft with one or more metal cutting tools disposed on a cutting head and a non-contact, pneumatic gaging device mounted on the shaft for rotation therewith. The measuring device is advanced into the bore formed by the tools so that it measures the inner diameter of the bore as the rotating shaft is advanced into the bore during the cutting stroke. Accordingly, a single stroke of the boring apparatus serves both to form a desired internal diameter and to measure the diameter formed during the cutting stroke. In a preferred embodiment of the invention, the tools are held by a positioning device which allow the tools to be moved radially with respect to the shaft so that the diameter of the bore formed by the tools may be varied. If the measured diameter deviates from the desired diameter, the positioning means repositions the tools as necessary to achieve the desired bore diameter on a subsequent cutting stroke.

International Classification:

G01B 1316

US Classification:

73 379

Abstract:

A method and an apparatus for determining the dimensional accuracy of workpiece surfaces, for example, of essentially cylindrical workpiece surfaces, wherein a measuring sensor scans the workpiece surfaces in accordance with a predetermined relative movement pattern between sensor and workpiece. The sensor is a pneumatic measuring head, so that the measuring procedure can be incorporated in the production process. The pneumatic measuring head travels over the workpiece surface along a continuous path which covers the surface area of the workpiece. The pneumatic measuring head is maintained at a constant basic or measuring distance from the workpiece surface, so that the measuring range of the measuring head is not exceeded when the measuring head travels over the workpiece surface. The measuring head continuously produces measurement signals, so that the measure procedure can be directly integrated in the production sequence.
