Methods involving adding a removable fixating material to a partially manufactured workpiece to stabilize a plurality of partially formed objects therein for subsequent manufacturing. In one example, a workpiece of interconnected structures is manufactured comprising precursors to the discrete objects as a function of a workpiece computer model. Manufacturing the workpiece further includes forming valleys between adjacent partially formed objects so that interconnecting portions remain to interconnect the partially formed objects. Further, the methods include removing the interconnecting portions so as to liberate the plurality of objects from one another. In some embodiments, a temporary frame is formed from the workpiece along with the plurality of objects during manufacturing.

Supporting device and method for large thin-walled part

A supporting device and method for a large thin-walled part is disclosed. The supporting device comprises a processing device and a supporting device. A workpiece is positioned between the processing device and the supporting device and is clamped at a periphery in a flexible clamping mode. A cutter in the processing device is connected with an iron core. A coil is wound on the iron core. When the coil is energized, a magnetic field is generated around the coil. A blade part of the cutter is in contact with a processing side of the workpiece. The supporting method combines the magnetorheological fluid technology with the jet supporting technology, and uses a jet impact force to offset part of a milling force. The current magnitude and winding mode of the coil are changed to control magnetic field intensity. The magnetorheological fluid is cured instantly to support the workpiece.

The present invention simplifies a support structure, and has the advantages of low cost, no contamination to a machine tool, and convenient use; plays a function of clamping the workpiece.

Method and apparatus for supporting blades

A method of supporting a cantilevered component mounted to a hub by locating a cassette in proximity to the cantilevered component, the cassette defining a volume for filling with an encapsulant; filling the volume with an encapsulant material; and causing the encapsulant to solidify to the cantilevered component to support the cantilevered component. The cantilevered component is preferably a blade on a bladed disc and the encapsulant provides support to change the vibration response of the blade during a subsequent machining step.

Method for machining metallic foam

A method of cutting metallic foams that eliminates the problem of smeared surfaces is provided. The method involves infiltration of the foam with another material to serve as a support structure to the foam when being cut. The method can be executed using softer polymeric materials such as waxes, which are then frozen for machining. These materials are subsequently heated and removed from the foam. In a similar manner, epoxy material can be used, which requires no freezing. In this method, the epoxy material is burnt from the foam upon completion of machining. The method allows for machining foams using conventional machining processes, rather than non traditional methods such as electrical discharge machining.
