Abstract

An apparatus for cutting a tubular part includes a carrying body configured to receive an end of the tubular part. In addition, the apparatus includes a cutting assembly disposed in the carrying body. The cutting assembly includes a continuous ring configured to be rotated relative to the carrying body. Further, the apparatus includes a first cutting element pivotally attached to the continuation ring. The first cutting element includes a cutting edge configured to engage and cut the tubular part. Still further, the apparatus includes a first actuator coupled to the first cutting element and configured to pivot the first cutting element between a retracted position and a cutting position. The apparatus also includes at least one sensor configured to measure a position of the first cutting element and a force applied to the first cutting element.

Abstract

A leg cutting system with a leg support clamp 2 with a height for maintaining a structural integrity of the leg 1 during and after the leg 1 is cut. The system includes at least two leg support clamp parts joined in at least one clamp structure joint 11 with releasable mechanical fasteners for joining or releasing the at least two leg support clamp parts along the at least one clamp structure joint. A wire saw 6 with a wire saw support frame 7 and longitudinal saw tracks 16 for longitudinal displacement of the sawing wire along said longitudinal saw tracks 16 can be fixed to the leg support clamp. A wire replacement unit 9 with a plurality of sawing wires with a joint allowing the wires to be joined is located adjacent the wire saw. The embodiment(s) furthermore relates to a leg support clamp.

Abstract

A leg cutting system with a leg support clamp (2) with a height h for maintaining a structural integrity of the leg (1) during and after the leg (1) is cut. The system includes at least two leg support clamp parts allowing the leg support clamp (2) to be installed around the leg (1). The at least two leg support clamp parts are joined in at least one clamp structure joint (11) with releasable mechanical fasteners for joining or releasing the at least two leg support clamp parts along the at least one clamp structure joint. A wire saw (6) with a wire saw support frame (7) and longitudinal saw tracks (16) for longitudinal displacement of the sawing wire along said longitudinal saw tracks (16) can be fixed to the leg support clamp. A wire replacement unit (9) with a plurality of sawing wires with a joint allowing the wires to be joined is located adjacent the wire saw. The embodiment(s) furthermore relates to a leg support clamp.
