ABSTRACT OF THE DISCLOSURE In rotary fluid machines in which the conversion of pressure energy of fluids is obtained by the circulation of at least two spaced vane members in at least one spiral-like passage of revolution in the form of a channel or groove, the rotary fluid part containing the channel is manufactured by a vane tool simulating the configuration of the vane members to be circulated in the channel and the rotary fluid machine part containing the vane member is manufactured by a disc tool simulating the configuration of the channels within which the vane members circulate. The method of manufacture employs a lathe machine combined with adapter mechanism permitting the vane or disc tools, as the case may be, to simulate the relative movement between the channelled part and the vane part in the rotary fluid machine. Where the channelled part for the rotary fluid machine requires undercut portions, the vane tool is of a reduced size, but otherwise simulates the actual vane, and the manufacture is accomplished by varying the angular displacement of the tool to either side of a normal center position so as to encompass the extremities of the law of movement of the actual vane member in the rotary fluid machine.
