Abstract
The present invention provides an aluminium near net material for making a rotary scroll. Even when there is a displacement due to level of die accuracy, error in machines used for machining processes and shift of processing fiducial, the invented near net material makes it possible to manufacture rotary scrolls without having skin of the original material staying in a finished rotary scroll, by determining the cutting margin 4 for spiral fin smaller than the cutting margin 5 for axis.
