ABSTRACT:
A method and apparatus for machining a matched set of fixed and orbiting scroll members for use in a scroll compressor. The respective wrap surfaces of the scroll members are simultaneously machined by respective rotating cutting tools. Specifically, rotational and linear movement of the fixed and orbiting scroll members together, synchronized with linear movement of the cutting tools, causes the simultaneous machining of the scroll members along respective wrap surfaces that form a radially inwardly moving sealing line of contact therebetween during compressor operation. Accordingly, any systemic or random deviation from a true involute form during machining of the matching of the matched scroll member set results in complementary deviations in the respective wrap surfaces, whereby a sealed relationship between the wrap surfaces is maintained at such point of deviation during compressor operation.
