Abstract: A measurement method for micro topography and roughness of internal surface of gap belongs to the technical field of precision measurement and is realized based on a measurement system which comprises a PC, a controller, a flexible mechanism and a measurement thin film. The measurement thin film has a copy function and is bonded to the flexible mechanism. The PC is connected with the flexible mechanism through the controller to control the flexible mechanism to expand or contract. The measurement method can effectively solve the measurement problem of the micro topography and surface roughness of the internal surface of the gap with a narrow inlet size. The method is simple and easy to operate, and the device is easy to carry, low in cost and high in measurement accuracy.

Abstract: 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.
