Number: 408/153
Name: Cutting by use of rotating axially moving tool > Tool-support with means to move tool relative to tool-support > To move radially > Moving means including wedge, screw or cam
Description: Device in which the displacement of the tool is caused either (1) by a member comprising a first and a second face, the faces meeting at an acute angle, adapted to be actuated substantially parallel to the first face, so that a tool slidably engaging the second face is displaced; (2) by a member having a helically- ribbed surface rotatable relative to a cooperating surface so that the ribbed surface and the cooperating surface are relatively displaced along the axis about which the helically ribbed surface rotates; whereby, a tool connected to one of the surfaces is displaced; or, (3) by a member which oscillates or rotates relative to the tool about a center and carries a surface composed of fixes points of varying distance from the center, which surface imparts motion to a follower in contact therewith, which motion varies in accordance with the varying distances of the fixed points on the surface from the center of the member.
