The programs for machining impeller airfoils were developed with HECTRAN, which is a proprietary processor for impeller machining programs. Impeller blisk 5 axis CAM software OPEN MIND 3 / 19. The programs which supply positioning information to this control for machining blisk airfoils were developed with APT and special programming techniques that were devised for these programs. This machine is directed by advanced computer numerical control. When the air flows through it, it will do work on the air and increase the flow rate of the air. The passage between the blades on the working impeller is expanded. The impeller is generally a part of a centrifugal compressor. The fixture is used to sandwich the impeller between a base plate and a top ring such that a plurality of tangs located on the top ring rest on the plurality of valley faces of the impeller. A new milling machine was designed for this process, which machines four identical parts simultaneously. Precision CNC Machining Titanium Impeller Blisk for Aerospace. The present invention provides a method of weld repairing an impeller by use of a weld restraining fixture. Army Troop Support, Aviation Materiel Readiness Command May 9, 1983. The blade surfaces of the integral impeller and blisk are functional surfaces for power transmission, and their surface integrity has significant effects on the aerodynamic efficiency and service life of an aero-engine. T-700 Blisk/Impeller Cutter Life Improvement Program N.

Five-axis precision contour milling was developed to machine the airfoils of the five axial flow blisk stages and the impeller, all of which are integral with their supporting disk. The integral impeller and blisk of an aero-engine are high performance parts with complex structure and made of difficult-to-cut materials.

Processes which were previously available, and which were used to produce airfoils for development engines, were too costly and too dependent on manual skill to meet volume production requirements.

This development was carried out under a Manufacturing Methods and Technology contract awarded by the Army Aviation System Command, which later became the Army Aviation Research and Development Command (AVRADCOM), to the Aircraft Engines Business Group of the General Electric Company in Lynn, Massachusetts. Impellers and Blisks centrifugal pumps axial variable pitched pumps shrouded impellers paddle applications backward curved propellers and turbo charger. Highly automated processes were developed to machine and control the quality of airfoils on the blisks and impeller which are the principal rotating components of the compressor for the T700-GE-700 engine, which powers advanced military helicopters.
