An example pipe cutting tool includes a plurality of actuators and a plurality of cutters. Each of the plurality of cutters is connected to at least one separate actuator of the plurality of actuators. The at least one separate actuator is configured to move the cutter between a pre-deployed and deployed position. The deployed position is beyond the pre-deployed position. The plurality of cutters may include a first and second cutter, with the at least one separate actuator connected to the second cutter moving based, at least in part, on one or more cutting conditions. An example method of cutting a pipe includes extending a first cutter to contact the pipe, cutting at least a portion of the pipe using the first cutter, detecting a cutting condition, extending a second cutter based, at least in part, on the cutting condition, and resuming the cutting using the second cutter.

An apparatus and method for removing the tops of trees, the apparatus including a rotatable first boom configured for coupling to and extending vertically downward from an aircraft and a cutting assembly hingedly coupled to a bottom end portion of the first boom. The cutting assembly includes a housing containing a motor, the housing having an upper portion coupled to the bottom end portion of the first boom. A second boom extends from a lower portion of the housing and supports thereon a singular circular saw which is operatively coupled to the motor. The second boom is arranged at an angle of about 30° to about 55° relative to the first boom. This accomplished by including bend within the housing.

The present invention provides a cutting work method comprising a cutting work step of forming a through-groove passing through from a surface to a back face of a workpiece material by cutting the workpiece material with a cutting tool while bringing a lubricant material for assisting cutting process into contact with the cutting tool and/or the to-be-processed portion of the workpiece material, wherein the workpiece material comprises one or more materials selected from the group consisting of a metal, a fiber reinforced plastic, ceramic, and a composite material thereof.

A machine forms a whip from a length of cable. The machine includes a clamping assembly, a notching assembly, and a cutting assembly. The clamping assembly includes a pad which can be move into and out of a cable travel space. The notching assembly includes a notching saw which cuts an outer jacket of the cable in a direction substantially parallel to the longitudinal axis. Movement of the pad also causes movement of the notching saw to move into the cable travel space or into a raised position. The cutting assembly includes a cutting tool which transversely cuts the conductors of the cable.

An exemplary embodiment of the present invention provides an apparatus for dismantling for heavy water reactor facilities, including: a cutting device configured to divide a calandria of the heavy water reactor facilities into a main shell and a sub-shell; and a transfer device configured to draw the main shell cut by the cutting device to the outside, wherein the transfer device includes a fixing unit configured to fix the calandria; and a transfer unit configured to transfer the fixing unit.

The present invention relates to a system and method for cutting and manipulating the used wind turbine blades for disposal.
