    Automotive Platform Lists

    You should be able to pull that through Powerway(.com), GMsupplypower(.com), or covisint(.com). If you don't have access, ask your OEM for a matrix. *Without data, you're just another person with an opinion.* Hydroformer

    Steel for Fineblanking-Low Distortion

    Is the contact point static or dynamic ? I imagine dynamic because of the fine-blank edge. If so, kinda sounds like a cam and follower application. I can't remember the mat'l type but GM truck hinges with an internal checker use this set-up. Buy a service part and have the cam analyzed. I...

    Multiple Machine Alignment

    Depending on accuracy required, I've used: - chalk line - high tension wire - surveyor's transit - laser - portable CMM (faro) *Without data, you're just another person with an opinion.* Hydroformer

    Testing would likely start with NVH (natural vehicle harmonics) longitudinal and torsional, using the unmodified vehicle as a benchmark. *Without data, you're just another person with an opinion.* Hydroformer

    runout tolerance

    MechEng13-"I would have to Third that checking for runout in a V-Block is not a good practice." And a fourth to that... There are tri-lobe shapes that will read 0.0 run-out in a 90deg V-block. I remember reading somewhere about using a 60deg V-block then a 90 and comparing the results...

    True Position of non-circular features

    Can you define the T-shape as a 4-way datum and tolerance the position of the circular disc (LMC) ? *Without data, you're just another person with an opinion.* Hydroformer

    OEM Initial engine break-in procedure.

    I am by no means an authority on this but in my experience I've seen that: at the engine plant, engines are fired up with a natural gas / propane fuel hood brought down on the manifold. Run time is only a few seconds (just to verify start-up). At the build plant: cars are driven off the line and...

    Anyone else using FaroÆs new Laser Scanner?

    I haven't used their scanner, but I've used their 'gold' 8ft arm. Our application was somewhat unique, they even wrote an article about it. I agree that Faro's tech support was great. We had a lot of trouble with the computers they supplied but particularly the software. I had the feeling we...

    QA Info on Drawings

    In automotive we identify 'key and/or critical characteristics' on the print. These can include safety items, fit or functional items, etc. that must be met (and monitored) for compliance. Additional checks (risk management) are applied to these elements. This is the design team's way of...

    Bumper Cars

    From the 'human factor' the events to consider are the vehicle making contact with an object, the occupant making contact with the vehicle (interior). Between these two events, the vehicle's structure needs to absorb as much of the energy as it can in order to lessen the secondary impact. (A...

    Fuel Flow Rate Gauge in Instrument Panel

    You gotta put it "in their face", maybe a HUD set-up. A warning tone/light at a preset pressure ? Or for habitual abusers, a set of pins in the seat to jab the driver off the throttle. *Without data, you're just another person with an opinion.* Hydroformer

    One point of forced induction/NA SI engine comparison

    Mark944turbo, I know it doesn't directly relate. But, it would change the air density through super-cooling, changing the air mass for a given stroke. (one of your parameters) Of course... the local gas station doesn't carry dry-ice. *Without data, you're just another person with an opinion.*...

    Fuel Flow Rate Gauge in Instrument Panel

    Yeah NickE, Manifold pressure is the best 'immediate' indicator. Many moons ago I put a vacuum gauge on my '72 Nova. I was young, I loved watching the needle move as I stepped into it. *Without data, you're just another person with an opinion.* Hydroformer
