All right, now we're going to we're going to cut this part off. Remember we did
grooving before - we want to get our dimension of a half inch thick on there,
but when we do the set up we want to add about a sixteenth of an inch to that
half inch so that we can come back and smooth it off and do a regular facing
operation. So we're just going to measure it right now to get our half inch plus a
little extra so we can face it off. Again we're going to run at 654 and now we
take into consideration here the thickness of the blade has to be in the
calculation as far as if you want to use your digital readout, okay.
Remember we're in minus - so we got to come back.
Ignore the minus (digital readout) there because we're working from the backside.
Okay, we've got about 1/16 extra on there which is what we want. Okay, so we're
ready to cut off. (Turns power on)
Now what you want to be careful of -
your part and this scrap material that's coming off of there . Be careful
because they're going to be very hot! This is also a manual feed operation, not
power.
You can also do this same thing on the bandsaw if you want to take it over on the
bandsaw and cut it off. I just like to do as much as we can on this machine and
then when we cut that off we can face it at the same time save a little bit of
time. That'll eventually just drop off on its own down in the scrap bin. Don't pick
it up - just about there,
there we go, dropped off.
All right so now we're going to change our tool. We've got our part cut off, okay.
So now we're going to have to do a facing operation. We took our cut off
blade out and we're going to put this back in to face off that edge there, get
it down to our half inch. Now remember this position is for turning right to
left. This position is for facing, okay. And remember that do not try to turn
with that turned in the other direction, okay.
All right again we want this edge here, remember
the straight is you can eyeball with a little bit positive, tighten her up.
Now once you set the center height on this if you take that out and put it
back in you don't have to change. It stays the same so we save that operation.
Okay, so now we're going to come over here get set up for the facing. Turn your
machine on and make sure that you don't use this lever here anymore. Here's your
feed lever here. Out is for this direction, in and out. In is for going
this direction. As you can see that's going for that but we want to face so
you can see it's going the wrong direction. We're set up now for facing.
We're going to take that down to a half inch. We'll check it with calipers and
get our half inch. It's it's a pretty open tolerance thing so it's not that
big a deal.
Once again like I mentioned, once we take that tool holder off and we have to put
it back on, your center height stays the same, so you don't have to worry about
checking that.
Okay, remember we only have to go a little bit past center, so let's check it
with our calipers and the see how close we are to 0.500. Now we've got about 35
thousandths to go. The reason why I zero those, just you know, so some cases
that'll confuse a student, so we wipe them out and start from scratch.
Sometimes you need to retain one of them.
All right, check it one more time and we are at 0.0500 - close enough.
We got a pretty sharp corner here and we want to take that off. Two ways you can
do it. One is to turn this again to 45 degrees which is a little bit you know
work wise and time wise, but we can also do it by eye. Remember this is 90 degrees.
Okay, half of that is 45 and it's it is strictly a guess where I put that on
there. And this is how we're going to take that that short corner off, okay.
Just want to turn it on, come over here like this, go straight in.
You notice, see what's happening there. We took that burr off and we got an angle
on it, okay. So a lot quicker. We've got kind of
a sharp corner there. We can do that same thing there. We might have room to do
that without turning too much,
at least we'll give it a try.
Yeah, we've got room. Turn it on, kind of move around like we did when we did
the threading to get a position that you can live with.
There we go, we got the same thing there and that's pretty much it.
