Abstract
Method for forming scroll members comprising an end plate having an involute wrap rigidly affixed thereto. The end plate and involute wrap are precision formed, e.g., by casting, either as an integral element or as two separate elements and then the scroll member is broached to the desired dimensional accuracy and finish. Push broaching is accomplished with an involute broaching tool which has a single terminating cutting edge on one or both sides of an involute blade cutter.
