Evaluating errors in screw rotor machining by tool to ...
Screw compressor rotors are machined mainly by form grinding or milling tools. The precision requirements imposed upon them are today so demanding that the tool is allowed only limited wear and must be well set in the machine. It is therefore important to be able to quantify the tool set errors as well as to compensate for tool deformation and ...
