TANDEM BLISK ELECTROCHEMICAL MACHINING

PROBLEM TO BE SOLVED: To attain electrochemical machining for a blisk used in a gas turbine engine. SOLUTION: A tandem blisk (12) is mounted into a multi-axis electrochemical machine (10). A first row of blades (18) are electrochemically machined in sequence. A second row of blades (22) are electroc...

Zusammenfassung:	PROBLEM TO BE SOLVED: To attain electrochemical machining for a blisk used in a gas turbine engine. SOLUTION: A tandem blisk (12) is mounted into a multi-axis electrochemical machine (10). A first row of blades (18) are electrochemically machined in sequence. A second row of blades (22) are electrochemically machined in sequence in the state that the blisk is still mounted to the machine. This machine is initially set up such that both stages are machined without removing the blisk between processing sequences. COPYRIGHT: (C)2003,JPO
