THIS INVENTION RELATES TO CARRY OUT VARIOUS MACHINING OPERATION FOR MANUFACTURING OF LOW PRESSURE TURBINE NOSE OF PARTICULAR AL31FP AERO ENGINE TO IMPROVE PRODUCTIVITY. THIS INVOLVES DESIGN AND FABRICATION OF VARIOUS FIXTURES AND CUTTING TOOLS SO THAT THE NOSE CAN BE MANUFACTURED IN ANY STANDARD 2-AXIS NC MACHINE WITH LESS DIFFICULTY.

摘要

This method is developed to improve productivity of LPT NOSE in batch production. Repeatability is being maintained for achieving the technological dimensions & technical conditions. By this improvised method, cycle time of the components has been reduced . Special purpose machine & its attachment for making 18 helical grooving is avoided by adopting this new process.
