Geometric reverse seeking and model reconstruction of key parts of shaking hammer

The working surface of key parts of shaking hammer is of reticulated structure that possessing the characteristics of "dense","thin" and "centripetal".It is difficult to determine its designing parameters by adopting the general measuring method,and also difficult to manufacture by applying the common machining technology and the conventional cutting tools.Therefore let the reverse seeking engineering technology be applied to the domestically produced design and research of manufacturing,so as to propose a data collecting method for the geometric reverse seeking course of the hammer's key parts.The digitization of practical parts was achieved based on coordinates measuring machine and tool microscope.By means of utilizing the least square method to carrying out analysis and treatment on the being collected data,the parameters of geometric modeling of parts were picked up and the model reconstruction of key parts by applying the Pro/E software was realized.The laying down of the manufacturing technology of this part and the design of cutting tools were guided by utilizing this model.The experimental result showed that the parts that being designed and manufactured by adopting the above stated method could accord with the needs of the practical production.
