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: An ultrasonic cutter detection method and device, the method comprises the following steps: preliminary detection: frequency amplitude detection and fall-of-potential detection, if the ultrasonic cutter fails the above two detection solutions in the preliminary detection, repeating the two detections; if the ultrasonic cutter still fails the above two detection solutions, the ultrasonic cutter is judged to be unqualified; and reinspection: free modal detection and pressure modal detection. Using differences of the ultrasonic cutters surface in micro-crack directions that result in different degrees of sensitivity of crack to different ultrasonic vibration modes, combined with the fall-of-potential method and frequency amplitude detection method, a detection rate and a detection velocity of an unqualified ultrasonic cutter can be improved.

Abstract: A method for measuring a surface shape of a honeycomb core includes the following steps: coating a reflective film on the surface of the honeycomb core to be measured, using a vacuum adsorption method to adhere the reflective film closely to the surface of the honeycomb core to be measured, and recessing the reflective film at a honeycomb cell downwards; and performing scanning measurement on the reflective film on the surface of the honeycomb core to be measured to obtain the heights of a honeycomb wall of the honeycomb core at different spatial positions. A device carries out the measurement of the surface shape of a honeycomb core.

Abstract: Disclosed is an automatic hole-processing method with self-adapting adjustment of processing parameters, including the following steps: performing tool feeding, detecting whether the rotate speed changes or not, if changes, judging the type of the processing material according to the new rotate speed after stabilization (if not, the tool feeding is continued); feeding the tool according to the processing parameters suitable for the material, detecting whether the rotate speed changes or not, if changes, judging whether the hole processing has been completed or not according to the new rotate speed after stabilization (if not, the tool feeding is continued), if completed, retracting the tool with the set parameters (if not, judging the type of the processing material according to the new rotate speed after stabilization, and repeating the above steps), completing the hole processing. During the hole processing in the present disclosure, there is no need to know the type of workpiece material of each processing hole in advance and to set processing parameters for each material respectively; there is no need for axial tool setting, processing parameters can be changed automatically after the tool contacts the workpiece; there is no need to know the total thickness of each processing hole material in advance and to set the feed stokes respectively, after cutting through the workpiece, the tool automatically identifies and begins to retract.
