Does anyone know where I can get low temperature properties, stress-strain curve, yield strength, modulus, for unfilled PPO+PS and 15% glass reinforced PP. I'm looking for properties at -20 degrees C.

I am interested in finding out if the field is moving away from using a general, or boiler-plate tolerance block on a drawing format or if most organizations are continuing to use it. Any opinions would be appreciated.

KENAT - You are correct. I want to dimension non-symetrical features from the centerplane rather than an edge of the datum feature. Thanks,

Can features be dimensioned from the centerplane of a true geometric counterpart of a non-cylindrical feature of size datum?

Can anyone tell me if there is an ASTM standard that is equivalent to AISI 1144 Straight (not Stressproof and not stress-relieved).

Thanks for your response. It's a fired porcelain finish as found on an appliance component so, my guess is, it would be resistant to most solvents.

Does anyone know of a solvent that will remove a medallion from a porcelain finish without damaging the surface? The medallion is fixed to the surface using an automotive trim type adhesive. This is a salvage need so quantities are low.

Does anyone know of a standard for formed sheet metal splines when the need for a standard involute spline isn't required?

Has anybody had any experience with the use of regrind in molding Nylind 51 HSL glass fiber reinforced nylon. Specifically, I am looking for a percentage of regrind that can be used without shorting the glass fiber length.

Other than cold cavity surface (less than 150 degrees F), what kind of molding conditions would contribute to the lack of a resin-rich surface of a gear molded out of Celcon GC25A?

I need to check the profile of the tooth surface of a 52 tooth, 17 NDP, 20 degree PA molded plastic gear. Does anyone know of templates which may be available to use on an optical comparator or, perhaps, of a better way to measure the gear tooth profile?

I remember when Y14.5 Standard for Dimensioning and Tolerancing first was introduced, the term applied for the tolerance of a hole location defined by basic dimensions was "True Position". Later, the term was changed and became "Position". Does anyone know if it has been changed back to "True...

I am looking for anyone having a bad experience due to changing from 301 to 201 stainless in thicknesses in the .035 to .045 range, specifically due to a cycling load.

The friction is only bonded to a small percentage of the surface of the part. The part has to pass a salt spray test.

Pro/E was origionally sold solely by Autotrol Technologies in Thornton, CO. At that time, while it was called Pro/ENGINEER, it was marketed as an Autotrol product and, since Parametric Technology had no interest in making drawings with Pro, it was marketed with Autotrol Series 7000 with Pro as...
