    I've been using the Okamoto and Mitsui grinders since they started showing up in the die shops back in the 80's. I didn't want to like them, being part of the Japanese invasion that began in the...

    I took formal classes in Pro-e when it was version 2000i and successfully mounted the drop-down menu learning curve. I was a big fan of PTC but needed to use other programs on the job. Most...

    -The seasoned tech that was breaking me in told me what might happen beforehand but said "You need to find out for yourself" and we had a replacement mirror. It amazed me how little it took to ruin...

    Can't help with the thread form/pitch but a lifetime ago I worked for American Optical as a field/bench tech. Cotton balls and Sparkle glass cleaner was what we used, wouldn't risk using an old...

    I took several classes in AC before moving to Pro-E (v. 2000i) when most of the stamping/mold shops were closing in 1999. My preference for PTC software was largely based upon having learned the drop...

    I use CAD all day and there's been occasions when I didn't properly constrain/designate a line to be horizontal/vertical/perpendicular/tangent. It was close enough to appear so on the screen but...

    It would help to have a good grasp of geometry and algebra. Trying to determine a solution is recognizing what is known and what is unknown. A good grasp of geometry and algebra helps to identify...

    You've not stated how many parts or the expected accuracy (tolerance) for the features, that makes a difference. I'd follow the suggestions others have made and use an edge finder on a finished part,...

    -No difference to split, I agree with you that when they think it's over IT IS OVER. Doesn't even matter what you did before. What have you done for me lately? As for the job, he's got to meet the...

    Keeping records of production and your own actions is not intended for legal purposes, unlawful dismissal lawsuits are an exercise in futility for all but a select segment of society. What I intended...

    An offer like that can go good or bad. You need to ask yourself "why am I getting the offer"? If you're real good at machining this may only be part of the answer. I was offered a job as Tooling...

    Tooling Engineer?

    I had presumed that the OP had not included a more descriptive account of all this due to being unfamiliar with the nomenclature and/or the intimate details of die stamping and was a desk jockey....

    Despite the attempts of the OP to include details there just aren't enough. Die design, especially at .0002 PS cut clearance isn't a casual conversation around the water cooler. No info on the shape...

    -Material, ferrous and non-ferrous, can fall into large groups with a range of speeds (SFPM) for HSS and carbide cutters. Machinery's Handbook has them but there are other sources. That should give...

    Possible? Not being familiar with the machine in question I'd say it probably is possible. It would be real good if your hired driver was sharp enough to see potential problems/solutions. It would...

    If your math skills are good, particularly trigonometry, then get a good feel for speeds/feeds of the different material groups. Get familiar with using an indicator (DTI) and how it should be used...

    OBTW- I haven't discussed the M,T,S, or PM groups of steels that are used in stamping dies because there are specific reasons for selecting any of these. I also have not mentioned coatings for the...

    You've not stated the material thickness so I'll presume that this is an academic question rather than questions with a job in mind. Fine. But asking questions about what the upper/lower components...

    I've used a rented drop bed trailer to move my BP alone, I've also hired a roll back wrecker to move a 5,000 lb. jig bore to my new location. The pallet may/may not make things easier, it will all...

    I've not read The Grinding Wheel so I can't comment on it but I don't think I've ever seen a book on surface grinding that I'd recommend either. Aside from wheel selection most information about...
