- [Instructor] A Jog Feature is an offset
in a sheet metal part.
The most common use of this feature is to
make an overlap from one part to the other,
so you can maybe spot-weld,
or screw the two faces together,
and you don't want them on different planes.
So to do that it's pretty straightforward and simple.
The first thing I need to do is create a sketch.
So I'm gonna go ahead and choose this surface right here,
start a sketch on that surface,
and then choose the Line command.
Let me go ahead and hit the Space bar,
so I'm looking straight down at that face.
Let's go ahead and just drag a Line over this part,
it turns black, because it's fully defined,
because it's snapped over that origin,
but you can pretty much put that anywhere you'd like.
Now, come up here to Sheet Metal.
Come over here to Jog.
And then choose the Fixed Face.
Now the fixed face I'm looking for
is this one right over here.
And if I click on that, notice it gives me
a preview of the Jog feature.
Now over here, I can change the amount of jog,
so I can push that up,
or I can pull it down,
or I can flip directions by using
this little arrow key here,
and I'm gonna go ahead and put it on
the bottom side for right now,
and then let's define whether we want a fixed projection,
or a standard projection.
So a fixed projection,
what that does is it continues or extends this material,
so that it always ends at the same place it started from.
So this flange was this long originally,
and if you add this Jog feature,
it's still gonna be that long,
but it's gonna be adding material.
If you turn that off,
it kinda sucks that material back.
So it doesn't add any material
it just uses the existing material and bends it,
and you can see here it actually doesn't
give you enough material to make that entire bend,
so generally using the fixed projection length,
it's gonna make a lot of sense.
We can also define how we wanna define the spacing.
So we can say an offset, or an outside offset.
We can do an inside style offset,
or we can do the overall dimension,
so a couple of different ways we can do that.
But over here, I would like to make this
the same as the thickness of the material.
So I'm gonna make my offset 0.063 right?
And you see there with the different options,
how we wanna offset this thing.
If you'll zoom in here, you can see these two bends here
coming together and there's a tiny little street section
right in the middle.
And if you wanna make the offset
just one material thickness,
actually these bend angles are too much,
so I need to change the bend angle,
so I can bring that face up,
so we only have one material thickness.
So to do that, instead of using 90 degrees down here,
let's go ahead and start changing this angle.
So notice as I change the angle to a smaller angle,
we get a little bit bigger section
in the center there right?
Just about 61 degrees is pretty much perfect.
And we'll switch to the outside bends.
So notice, we have this flange here,
that's pretty much right at the bottom
of the existing flange,
and that's pretty much what we want.
We'll be able to extend the flange on the right
over the new jog feature,
and then be able to spot-weld the flanges together.
So right there at 61 degrees,
with an offset on the outside offset
we're looking pretty good,
so go ahead and click on Okay.
And if you get a warning like this, it's okay,
just saying it's less than the minimum for the Jog offset.
Most of the time you can get away with this
with a one-material thickness offset,
which is very common in sheet metal.
So once you have that,
we need to now extend this surface over here.
So let's go ahead choose that surface.
Let's start a sketch.
I'm gonna go ahead and start from
this upper corner over here,
and drag this down, and let's go ahead and Snap
right to the beginning of that Jog.
Alright, let's go ahead and see it in 3D.
So there's my new feature.
And then come over to Sheet Metal,
and click on Base Flange/Tab,
and it's gonna go ahead and create a tab feature.
Click Okay, and there it is.
Now we can easily spot-weld this,
or if we wanted to we could drill some holes in there,
and screw it together, or rivet it together,
there's a whole bunch of ways
you can join that sheet metal,
and again, inside of most sheet metal shops,
a one-material thickness job
is a very, very common feature.
Now we do wanna show you
one another style of Jog,
so I'm gonna switch over to my second example here.
Which is 2.8.2,
and let's go ahead and create another sketch
on that top surface.
I'm gonna go ahead use Line.
There it is, and let's go look straight down at that,
and everything looks pretty good,
let's Snap this to that surface there, or that edge.
Let's go ahead and create one more Jog.
Here's our Jog.
We're gonna make the Fixed Faces one here.
And then let's go ahead and just make this
a little bit taller.
Push that up to 90 degrees.
And in this example, I just wanna show you
a couple of the different options for Jog position
and Fixed Projection Line.
So right over here,
let's Zoom In on this bottom section here.
Right now we have the Jog position
at the bend center line right?
We can also switch that back to
this material inside condition,
or we can switch over here to
the material outside condition,
or we can have it be bend outside condition so,
we have a bunch of different options
of how we'd like to form that Jog,
based upon the sketch that we added.
This is very similar to what you'll see
in a regular edge flange.
We've already looked at the Jog angle,
but we also have the option below that,
for a custom bend allowance.
And most of the time,
you do need to use some type of a custom bend allowance
for this type of feature,
because it's not necessarily gonna be a 90-degree bend,
or you might wanna talk with your sheet metal supplier,
far as the type of Jog you're gonna be doing,
so you can get the correct bend deduction
or bend allowance or k factor in there,
so that the flat pattern is the correct size.
But I just wanted to go over those few options
for creating the Jog.
The Jog is very similar to just two edge flanges
created at the exact same time using the Jog feature.
