A Study on Machining of Impellers with Ruled Surfaces

Impellers are important components in the field of precision machine, energy
technology, and aerospace industries. Due to their complex geometries and higher
degrees of interference, to produce a impeller with high precision dimension is a
challenging technology.
In this study, flank milling is used to machine blade surfaces of impeller instead
of point cutting. Flank milling can provide a surface better than point cutting without
addition processes. When blades of an impeller are designed by ruled surfaces, the
impeller can be machined by flank cutting technology. Based on the type of a five-axis
CNC machine, the objective of this project is aimed to develop the technology of five-axis
machining for impellers. The involved techniques are : the identification of undercutting
in flank cutting for ruled surfaces, five-axis tool paths generation, coordinate transformations
for five-axis machining, and determination of cutting parameters. In addition, a practical
application example is provided to show the feasibility and effectiveness of the developed
procedure.
