I've come up with a tensile strength of somewhere around 152ksi per the HT that will be performed. The tensile requirement on the drawing is 115ksi. Couldn't this be to brittle now? This is what I'm talking about. Somewhere here says well it meets it then. Well to me not necessarily. just...
O.K. so here is the outcome so far. I have been less then successful in trying to get engineering and the president to put specs on the drawing. Our purchaser purchased 4340 / AMS 6415 per engineerings recommendations. The material certs do not show elongation, yield strength, or tensile...
I am a Quality Manager at an AS9100 Registered Company. We currently have a fairly new V.P. of Engineering. Of course we are already clashing. Go figure. Anyway our manual basically states that engineering will provide a material specification on drawings, basically to provide purchasing with...
Thanks guys, I understand the need for the tight tolerance, we do however perform balancing on the rig prior to it making speed. I quess my worry is if we are holding A-1 machine company to a dia of say .551"-.553" and we measure a Dia of .5531" there is definately room for error there, who is...
Hello everyone, I'm a newbie here. I can't say I'm a diploma'd engineer, I am more of a hands on kind of guy. Anyway I have been in Aerospace for 15 years now, almost half my life, mostly spent in turbine engine repair. I have recently picked up employment in a High Speed Testing faility. We...
