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.

1. Description:
Screw compressor is a displacement of the rotary volume machines, it
mainly by the meshing of a spiral rotor component, in the case, do rotor
rotary movement, with its volume of the rotor spinning change. Today's
main rotor was a screw-type, used for milling or grinding. In either form
of processing by the rotor, rotor can be used to define the coordinates
of their geometric char
