11:00 the superfly gives you a shiny surface, but not necessarily a flat surface. The larger diameter of the tool magnifies any tram error that you might have. Using a small diameter end mill, say 1/2", for your facing will give you a less nice looking finish, but probably better flatness.

@stevendoesburg65556 жыл бұрын
Brandon Fuchs I would expect that, with a little care, a mill can give more than adequate results. It looks like this is already flat enough. If used properly using the surface grinder will result in better flatness, but good enough is good enough.

@@stevendoesburg6555 considering the accuracy of a vise determines the accuracy of everything you make in it, I wouldn't advise on going with a method of inspection of it that knowing includes errors that will compound in everything produced in it.
@stevendoesburg65556 жыл бұрын
Erstwhile without extra effort the workpiece will have a squareness determined by the squareness of the vice. The flatness of a face is not determined by the vice. At most the parallelism of two opposite faces are affected by the accuracy of the vice, depending on how the part is clamped.

The diamond pin running parallel to the jaw is going the wrong direction. If you are going to use 2 diamond pins they should be in the same direction. Really you should have 1 round pin and 1 diamond pin to get the best results.
@JFettig1116 жыл бұрын
I noticed this in a previous video. The only reason it's "working" is because there is enough bearing surface on each of the diamond pins.
@Motorman02976 жыл бұрын
Hey I’m not the only person who noticed. The diamond pin that is parallel to the jaw defeats the whole purpose of trying to make sure the jaw face will be parallel to the fixture plate. Hey but at least it will be repeatable from side to side. :)

You are correct about needing a round and diamond pin. Two diamond pins in the same direction would also work for this application.

@jayosborne15656 жыл бұрын
a fixed round & diamond pin (4way & 2way) would be correct... if a tangent line made by the two holes' outer edges was called out as the datum...(which is what will happen to the part as it is forced in that direction from the indicators springs) which i doubt it was! a line formed by the center axis of both holes is a more realistic datum! for this reason, two spring loaded taper pins should be used. the second pin should have relief in the non locating direction. as a bonus, that relief should be ground to enable an attribute check of the two holes pitch to one another! parallelism should not be called out to MMC modified datums... a cheaper check would have been to callout the datums @ MMC and callout the wall as profile of a surface (or line) then have a machined wall at some clearance from the wall we want checked. then a simple go nogo check with a feeler gauge will do!
@nraynaud6 жыл бұрын
I think you can go with only one indicator and replace the other one with a hard ball. you are just checking a parallelism. To calibrate the tool, you can put 2 hard pins in the holes, put a parallel or a gauge block against the pins and set your indicators against that. This way you use only inspection items during your calibration.
@PuzzleboxProps6 жыл бұрын
unless im missing something i don't know that would work. Assuming you mean one side would be fixed ball it might cause issues since the actual distance from the pins to the flat face probably varies. Again maybe im not understanding what you mean tho.
@jakubswietlik71376 жыл бұрын
nice idea. What of deviation is acceptable for you on indicated parallelism? I'm asking because small deviation of pins or holes diameter will cause parallel measure misteak.

Will this be inspecting material harder than aluminum? If so, wear overtime can cause the gauge to become inaccurate. If gauging aluminum, use something like 4140 pre hard if steel, use A2 and heat treat to say 55-57 Rc. Will give a long life tool that will resist wear and tear.

If you pause around 10 seconds, it looks as if there is some kind of steel bushing, almost like a drill bushing pressed into the holes. I could be wrong though.
