A cutting device capable of efficiently cutting an object with a simple configuration includes a grasp unit including a first grasper and a second grasper movable in an opening and closing directions to grasp the object, a cutting unit disposed side by side with the first and second graspers and moved in a cutting direction along the opening and closing directions to cut the object, and a position setter setting a cutting start position and a cutting end position based on respective positions of the first and second graspers that are grasping the object, respectively.

A device and system comprising a cutting torch system including a multi-fuel adapter specially adapted to convert a gasoline oxygen cutting system to a multi-fuel cutting system and methods of using the same. The invention also includes a portable system including a carrying case for use with the multi-fuel adapter.

A portable device for precision plasma and oxy-fuel torch cutting is provided. Versions of an example portable cutting torch tool guide the gun of a cutting torch to make precision linear cuts or curved cuts in a metal workpiece. In an implementation, the device is a gun for a cutting torch, with an integrated rail follower and adjustable vertical and horizontal offsets from a workpiece. The cutting torch tool may use various kinds of rails for stable cuts, with optional movement damping, motorized drive, servos for vertical and horizontal offset, and remote control with user interface.

Shaping systems and methods suitable for cutting a material, and deburring devices for performing a deburring operation on an edge of the material. Such deburring devices include a manifold having at least first, second, and third nozzles having first, second, and third axes on different first, second, and third planes, respectively. The first, second, and third nozzles are adapted to project first, second, and third gas streams therefrom in the first, second, and third planes axes. A mechanism is provided for orienting the manifold to project the first, second, and third gas streams at the edge of the material.

Methods and devices for supporting a workpiece on support slats of a workpiece support during machining of the workpiece by thermal separation by a separation beam directed onto the workpiece are provided. In one aspect, a support slat includes support projections on a workpiece side extending in a longitudinal direction of the support slat. The support projections follow one after another in the longitudinal direction at a mutual distance to form projection gaps. On an underside of at least one support projection remote from the workpiece side, the support slat defines a recess covered by the support projection toward the workpiece side. The recess extends in a transverse direction of the support slat. The support projection covering the recess is separably connected to the rest of the support slat and is separable from the support slat with opening the recess toward the workpiece side.

An apparatus and method for supporting and severing an object of interest is described and which includes a frame for positioning an object of interest which is to be severed; a cutting device which is selectively mounted in spaced relation relative to the frame; a multiplicity of orientation units mounted on the frame and which are adjustable, as to length, to maintain the object of interest in a predetermined orientation while being severed; and a controller operably coupled to each of the cutting device, and orientation units, so as to effect an optimal severing of the object of interest while maintaining the object of interest in a given planar orientation on the frame.

In known methods for through-cut detection in the thermally assisted through cutting of a workpiece, the workpiece is subjected to a first alternating signal. A method that allows a fast and accurate detection of a through-cut made comprises the method steps of detecting a second alternating electrical signal caused by the first alternating electrical signal in a measurement electrode spaced from the workpiece, determining the phase shift between the first and second alternating electrical signals to output a phase shift signal, and detecting a temporal evolution of the phase shift electrical signal or a measurement variable derived therefrom in a predetermined time interval. When a workpiece through-cut is made, it is detected in that the phase shift signal or the measurement variable derived therefrom is in the time interval within a predetermined fluctuation range.

A method for cutting a plow bolt hole in a work piece using a cutting torch includes receiving a computerized part file including elements representing holes to be cut in the work piece. An element is selected and assigned a plow bolt hole identity. The selected element is associated with an aspect of an inner shape and an aspect of an outer shape of the plow bolt hole. A tool path is developed for the cutting torch that accounts for the aspect of the inner shape and the aspect of the outer shape and is associated with the selected element. Instructions are output to a computer numerical control (CNC) machine to move the cutting torch along the tool path so as to cut both the inner shape and the outer shape of the plow bolt hole in the work piece consecutively without interrupting a flame of the torch.

The invention relates to an ozone supply unit (26) for a flame burner apparatus and/or an oxygen cutting apparatus (10), comprising an oxygen inlet (28) to be supplied with oxygen (18), an ozone generator (32) coupled to the oxygen inlet (28) and configured to convert at least a part of the oxygen (18) supplied to the oxygen inlet (28) into ozone (18a), and an outlet (30) coupled to the ozone generator (32), wherein the outlet (30) provides at least a part of the oxygen (18) supplied to the oxygen inlet (28) and at least a part of the ozone (18a) converted by the ozone generator (32). The ozone supply unit (26) is configured to be integrated into a flame burner apparatus and/or an oxygen cutting apparatus (30). The invention further relates to a method for supplying ozone to a flame burner apparatus and/or an oxygen cutting apparatus (30).

A system for performing exothermic operations or oxygen delivery uses a rod and handle configuration to create a flowpath of oxygen. The rod includes cables having stainless steel fibers that burn using the oxygen within a hollow center area. While burning, the rod cuts through material. A sheath covers the covers to contain the gases and prevent unraveling of the cables. The handle attaches to the rod and provides control of the flow of oxygen to the rod. A manifold fixing in place bottles of oxygen connects to the handle and can be fixed to provide different mixtures from different bottles. The rod is disconnected when needed to fix a mask thereto for delivering breathable oxygen to a patient.
