Screw compressor rotor machining tool wear the geometric calculation method [Abstract]: screw compressor rotor milling and processing a grinding two methods, usually conducted in two phases processing; first stage is rough, when the workpiece to be processed about its size to the second stage of Finished, when the rotor be processed into its final size when completed. Materials or cutting cushion in the finishing was removed, it is by milling, grinding and cutting tools determined by the design. Taking into account the screw compressor rotor is a spiral shape, in the process of cutting, cutting tool on every point of contact with the rotor of the horizontal length is not the same, therefore, finished at the rate of wear and tear tool of its type along the line is Inconsistent. Envelop the meshing theory be used here in terms of the process of cutting tool on every point and the relative motion between the rotor. To a certain scale, in this relative movement of assumptions, calculated on every point of the tool wear rate. By calculating the results and experimental tool that the rate of wear and tear, we can see that both the conclusions are the same. On this basis, can know how to create a rough time so that semi-processed materials while the thinning tool and thereby facilitate the finishing tool at the same rate of wear and tear. A similar technology is being applied to many of the machines during processing, and forming a variety of knives were also used for these technical.
