We've just completed step number six on your process sheet. We're going to move
on to seven which is putting a line on there to determine how far back we're
going to go on a 60-degree angle. So we'll go ahead and do that. We've done a
touch off before so we're going to come up and just lightly touch off here, okay.
And zero our readout on the z-axis and if we look at our process sheet we're
going to put that line on there at one-inch 0.220 so we'll go ahead now
We zero it up on our digital readout and we're going to move on the z-axis to
one-inch 0.220.
Okay, we're .221 and right now we are
1.220 so we're going to turn the machine on. We're still running
at 654 to do this RPMs so we're going to go in till we just barely touch so that
we can see that line clearly. There we go there's our line okay we're going to
shutdown. Come out here and we're going to have to change the angle on our vise
to 60 degrees to the rear rather than at the front.
Okay, now the protractor, remember the protractor is is on your compound on the
lathe here and we want to get sixty degrees. Usually you have to wipe this
off to make sure you can get the right angle because if we don't we won't get
what we're trying to attain. All right we've got our base on sixty degrees now
we're going to tighten it up then we'll have to loosen up our post
here so that we can position this where we can do that angle. On your process
sheet and on your print you'll see you're kind of a picture of that. Now any
time we move this compound to different angles or different sides your center
height does not change so you don't have to worry about that. Okay, so we're
going to turn this to where we have to get in right here in order to put that
sixty degree angle on there.
And then we will continue to get that 60-degree angle until we get to that
line. So we want a slight angle on this this way that looks pretty good there.
Now, this is not going to be a power feed situation it's going to be manual and
you will I'll show you here in a second. We'll be feeding it back here. Starting the
cut. Now after we take a few cuts here you'll be able to see that angle on
there. So we're going to continue to do this until we get back to that line and
then we're there where we need to be according to the print specs. See how
that want a line is getting wider and you can now detect that angle.
You don't have the capability on the machine to power feed this right here
only on our X and Y axis which is back and forth and in and out.
We got to be very careful that we don't hit on here so you need to watch this
closely.
We just get all far enough we can get in
see how the angle area is getting wider on every cut. Now that groove that we put
in there on the last operation, you can see why that's there because it's
clearance that we can get in there.
Probably one or two more cuts will take care of it.
As soon as that line disappears we know we're there.
Alright, this will probably be the last cut so we're going to take it kind of
slow so we get a good finish now maybe one more might do it.
There we go we're there now.
Okay and that's it now we'll go ahead and we're going to move this back to 30
degrees where it was for all of our other turning and facing that's normally
where we put that.
