Abstract:
A quick setting and release actuator (10) for cooperating with an axially movable chuck for holding a tubular workpiece (24) in fixed position includes an anchor member (12) that is fixed relative to a housing of a machine tool (20) and a thrust member (42) carried by a pivotally mounted carrier member (38) that pivots towards and away from the anchor member (12) to drive the thrust member (42) into engagement with the end wall (44) of a multi-segment collet (26) to cause the collet (26) to ride along its segment bearing surfaces (30) to engage the periphery of the workpiece (24) to be retained in the machine tool (20). Thrust member (42) may be pivotally mounted by a pivot connection (48) on the carrier (38) so that the thrust member (42) will align itself with the end wall (44) of the collet (26) even when the carrier (38) is not precisely parallel with the collet end wall (44).
Abstract:
A cutting tool and track system includes a multi-segment track assembly configured to be removably attached to a surface of a workpiece, a carriage assembly configured to ride along the track assembly, a carriage drive mechanism arranged to drive the carriage assembly along the track assembly, a cutting tool assembly connected to the carriage assembly, and a tool driving system connected to the cutting tool assembly. The cutting tool assembly rotatably supports an end mill type cutting tool that may be driven in a radial cutting plane about the axis of a tubular workpiece or along a workpiece surface. A method is provided for cutting a workpiece wherein a cutting tool assembly rotatably supports an end mill mounted for travel along a predetermined transport path in a cutting plane about a central axis of the workpiece wherein the end mill is first fed through the wall thickness of the workpiece and the cutting tool assembly is moved along the transport path in the cutting plane to cut the workpiece.
Abstract:
A cutting tool and mounting system includes a tool carrier arranged to be mounted onto a workpiece, a cutting tool assembly carried by the tool carrier, and a tracking assembly connected to the cutting tool assembly and positioned to follow the contour of an outer surface of the workpiece. The cutting tool assembly includes a cutting tool arranged to be rotated about a longitudinal axis and a tool driving system connected to and arranged to transmit rotary input motion to the cutting tool. The cutting tool is secured by the tool driving system to be fed along its axis of rotation and transversely of its axis of rotation for cutting a workpiece through a wall thickness of the workpiece to impart a beveled surface to a severed end portion of the workpiece.

Abstract:
A system for aligning and guiding a weld head or torch (5) along a desired weld path includes a travel mechanism for moving a weld head assembly (1) along a fixed path and a steering mechanism for moving a weld head or torch (5) relative to the fixed path in order to follow a desired weld path. A method of establishing the desired weld path includes the steps of establishing coordinates of the path by moving the weld head or torch (5) to positions along the desired path and recording locations of the weld head or torch (5) at the desired positions. Movement of the weld head or torch between the coordinates is achieved by interpolating a path as the weld head or torch (5) is moved from one coordinate to the next following initiation of an automatic steering program.
