A cutting apparatus and the method of operating same is provided. The apparatus includes a feed tower assembly configured to be attached to an object and a frame base plate movably attached thereto. The frame base plate has a pivotable arm assembly and an arm wheel thereon which accept a cutting member. A visual tension indicator is operably connected to the frame base plate and the arm assembly and configured to indicate an amount of tension applied to the cutting member.

A mobile ordnance disposal system to dispose of unexploded ordnance in situ by cutting open the ordnance casing and subjecting the explosive material to heat in order to burn the explosive material held within the casing in a controlled manner instead of generating an explosion to effect disposal. By using the system, the operator may remain at safe, remote distance controlling the system operation.

A method cuts slices from workpieces using a wire saw having a wire array, which is tensioned in a plane between two wire guide rollers supported between fixed and floating bearings and having a chamber and a shell. The workpiece is fed through the wire array along a feed direction perpendicular to a workpiece axis, while simultaneously changing the shells' lengths by adjusting a temperature of the chambers with a first cooling fluid in accordance with a first correction profile specifying a change in the shells' lengths based on the depth of cut. The floating bearings are simultaneously axially moved by adjusting a temperature of the fixed bearings with a second cooling fluid in accordance with a second correction profile, which specifies a travel of the floating bearings based on the depth of cut. The first correction profile and the second correction profile are opposed to a shape deviation.

Slices are cut from workpieces during a sequence of cut-off operations by a wire saw, having a wire array. The wire array is tensioned in a plane between two wire guide rollers supported between fixed and floating bearings. During each cut-off operation, a workpiece is fed through the wire array perpendicular to a workpiece axis and the wire array plane. The workpiece is fed with simultaneous axial movement of the floating bearings by adjusting a temperature of the fixed bearings in correlation with a first correction profile, which specifies a travel of the floating bearings in dependence on the depth of cut. In dependence on the depth of cut, operating parameters are set, such as the feed rate, an amount of working fluid fed to the wire array per unit time, a temperature of the working fluid, a wire speed, a wire consumption per cut-off operation, or a wire tension.
