To construct a parallel-axis rotary piston machine having a helically twisted outer part (2) and a likewise helically twisted inner part (1), which parts (1, 2), having a thread number differing by 1, intermesh and rotate relative to one another and revolve eccentrically, the engagement surface (3; 4) of at least one of the parts (1; 2) is machined with a tool (19) fitted with cutters and rotating about a rotational axis (II; I) parallel to the axis (I, II) of this part (1; 2). …<??>To efficiently machine the engagement surfaces with the best surface quality, a tool (19) fitted with cutters on the end face and circumference is used to machine the engagement surface (4) of the one part (2), the circumferential cutters (20) of which tool (19) are adapted with regard to arrangement and cutting-edge pattern to the profiling of the engagement surface (3) of the other part (1), and tool (19) and part (2) to be machined are subjected to a relative feed which is composed of a basic movement corresponding to the relative movement of inner and outer part (1, 2) and of a helical movement superimposed on the helical twist. …<IMAGE>… |
