    advice on giving dimensional tolerances

    If you manufacture just the male component part that fits into the connector you should base your dimension and tolerance scheme on the connector because it already exists. Fill what's empty. Empty what's full. And scratch where it itches.

    Conduit cut-outs in sheetmetal walls

    I would also grab a copy of UL 50, that is the standard that UL would use certify a sheet metal enclosure. If your in Canada you can grab CSA 22.2 No 94 (I think, that is out of the top of my head). Fill what's empty. Empty what's full. And scratch where it itches.

    DNC stips out first line of program

    It sounds like it is not recognizing the end of the first line (program number). If you can't figure it out you could always put several (Delete this) lines in the program after the number and that will at least buy you a few free transfers without losing data. It really seems like it must be...

    Vibration problem

    It could be a million things; When was the machine last leveled? How long is the tool? How old is the machine? If the center of the part is left as stock is the length causing a off balance whip? ..... Fill what's empty. Empty what's full. And scratch where it itches.

    tech needds help with daily report

    "To the best of my knowledge" That is a disclaimer, now I am having to rely on your knowledge and the code is almost meaningless. This statement becomes pointless in my opinion. If you drop the first part, the sentance has more meaning. "The observed work conforms to the workmanship...

    How to get around sanding casting iron before machining?

    Sounds to me like you should be able to throw them in a vice and face mill them. Possibly more than one at a time depending on part size. Determine a percentage of clean up you need (say 50% clean up lets you flip it and sit flat). Sanding them is going to be more expensive then popping them...

    machining environment

    Room temperature is usually considered around 68 degree, but I don't believe there is a standard manufacturning temperature. Usually if a part is expected to perform under specific enviornmental conditions they are stated in the contract and inspections usually are conducted at those...

    What does TYP (Typical) mean on a drawing?

    In plain english, if there is 10 holes on a part and it reads ".250 dia Typ" then all 10 holes are .250 dia. Fill what's empty. Empty what's full. And scratch where it itches.

    Biggest Machining Mistakes

    I could write a book on the things I have seen. First one that comes to mind, I saw a guy take a Case Harderned 48"x 1.5" x 2" bar (cut on one side like a flight of stairs in .125 steps w/ 7Degree angle to them)... anyway he took this hardened bar and was getting setup to finish grind it. He...

    robotically weld thin material

    We mig and plasma weld .036 - .06 on a daily basis. It was troublesome at first. Fixturing is humongous, make sure your fixtures locate the parts consistently. If you are welding galvanized material be aware of the zinc vapor issues. Fill what's empty. Empty what's full. And scratch where...

    Machining Internal Corners / In Corner Cutting

    Sounds like you may be best off drilling a .02 hole in the corners then rough the slot with a .06 end mill, followed by a finish cut with a .032 end mill. Follow up with a file to hit the corners, you will only have to remove about .01 - .015 with the file. (Downside to that is you will most...

    "manufacturing" drawings ?

    I am suprised by the whole story. The manufacturing drawings are pretty common things for companies. We create our own drawings for everything we make, our design or the customers. If the customer supplies a drawing we re-create our own regardless of the job. Most of the reason is for our...
