    Traceability for castings

    I was asked by a company what could be done for traceability(date of manufacture, lot number, etc.) in investment castings similar to date code wheels in plastic tooling. What is usually done and what would help in this area?

    Glycerine crystallization

    I have a problem in a sealed area with glycerin forming white chunks in a liquid filled gage. The are white and seem to sray around the clear gasket by the window. It feels like grainy crystals and it clings to the metal wall in two places. Looing for ideas of what could possibly cause it.

    Multiple Qualifications for Engineers

    In the spirit of lean manufacturing and the future, how many engineers out there have had a product and enough financial know-how to get it going? The title of this topic is where is engineering going and I think this is a direction people should take when they can. Design a better product, make...

    64 BIT MACHINE

    I have AUTOCAD LT 2000 and recently purchased a 64 bit machine. The salesman told me that Vista can be made to ask how to run the program when it is installed. Big news, Vista doesn't ask and the computer tells me that the program isn't compatible. Is it time to move on?

    I have a new TPE development part that needs to feel like rubber (approx. 50-55 duro shore A), be injection moldable, not flash on a knockout pin and take either a digital transfer print or ink on a cut raised 2-D surface. It needs to go through wash cycles and take outside weather conditions...

    High Speed Steel M-17 grinding

    I need to get some parts ground 0.350" long down to 0.009" dia. at the very tip. CNC type profile and Rc=60-62. Starts with a die pin at diameter and the o.d. profile is on the last 0.150" of length. Do I cut then harden? Getting no takers.

    Lubrication of sliding components

    The information on lubrication of stainless screws was very informative. I have a question as to turning components. Close tolerance with a gap of 0.0003". At temperatures up to 600 deg. F, would the same lubricating materials be useful? Or would a coating such as Titanium disulfide be a good...

    Are there any actual legal policies determining what constitutes a sick day, vacation day, etc. for exempt employees? Is it right for a company to not compensate you for extensive travel and yet dock you for sick time even if it is a necessary doctors appointment? Just wondering what actual...

    CUTTING IN A HEX HEAD

    What is the easiest way to machine a hex for a 3/16" allen wrench on the head of a stainless steel insert 0.600" long. Precision machining of the rest of the insert is involved so no hammer shots please.
