Every point along the axis of the hole is a nominal [x,y,z] distance away from the [0,0,0] origin point. You can imagine as the 3 flat surfaces grow towards max material, that will change where the Z0 of you coordinate system is relative to the perfect one and with it, shifts up the cylindrical...
This may be a stupid thing to ask but I can't find much at all about this online. Has anybody tried threading using a mill boring head?
I have a thread form similar to a square thread that I'm trying to cut and the part needs to be done complete on a 5axis mill. Thread milling isn't going to...
Hi CheckerHater,
unfortunately no, the remaining dimensions are independent of the thread form and the only reference to a standard is the ASME y14.5 for GD&T interpretation.
Hi all,
I'm looking for advice on how to deal with a customer's thread callout on their print. It is an internal dual-lead 60° v thread, but the concern is that they define the nominal and tolerance for major, minor and thread pitch, but there is no pitch diameter callout. My concern is the...
Thanks all for the replies and insight, especially you chez. Thinking about it in terms of the coordinate system and a vector that cares about that cares about the one extra point of travel along the 3rd axis has really helped me understand this a bit better.
As for the theoretical point...
Hi all,
I had a customer print come in recently with a surface profile callout that was very unusual for me and I wanted to run this by some people to see if this is allowed, or even makes sense to anyone else. I modeled up something simple to emulate the true parts datum structure and surface...
