Welcome to FreeChat new session. In this session we will model this sheet metal part in FreeChat with the help of a sheet metal workbench
So let's start. So here I have activated my part design workbench and I will create a new file
And to model this part we require a body. So we will create our body and then we will create our sketch
So here I have set my view to orthographic. Now we will read the dimensions
So as we see our sheet metal part. So we can see that this part having the four flanges
So we have 1, 2, 3 and 4. So for this flange we will first create a rectangle
And then we will make this four cutouts. And then we will make this four flanges
And then we will adapt our rest of the features. So this will be our modeling approach
So first I will select this xy plane and I will say sketch
And now I will go to the tree view, hide my origin plane. I will select the rectangle tool
And now I will make my rectangle symmetric. So I will select this point, this point and this center one
Now I will give my dimension. So it is a 200. And height is 50. And width is 90
So height we will achieve in the flange. So we will give width 90. So I will select this line and give my dimension 90
So now our sketch is fully constrained. So I will come out of the sketch
Now here we have made our sketch in a part design. Now we will move to the sheet metal workbench
Now we will select our sketch and click on this make base wall
So here we can see that our first feature has been created. Now if we see our drawing, we can see that our sheet metal is 2mm thickness
Now we will assign the 2mm thickness to our base feature. So for this, I will click on my bench and we will go to the data. And in data here you will get option of thickness. So I will give here the thickness 2
So now it is 2mm thickness. Now we will make the 4 flanges of 50mm. Before that we will add up this cutout. So I will select on this face and switch to the part design
And create a sketch on this face. Now we require these 4 edges. So we will convert these edges into the sketch entities
So I will click on this icon external geometry and I will project all the 4 edges which are required
And now I will create 4 rectangles. So I will select rectangle tool and first I will draw the 4 rectangles
And now we will read the dimension of our cut. So here if you see it is 200 and this is 120. So 200-120 is 80. So this will be the 40
And here it will be the 40. So we will give our dimension. So this one will be the 40. So I give here dimension 40 and this line and this line will be equal
So I will select these 2 lines and give it an equal constraint. Same way I will select this one and this one also and give the equal constraint
So here we have got the dimension 40. Now from the side view if you see it is a 90 and it is a 50. Length of this line is 50. So 90-50 is 40
So from here to here it will be 20 and from here to here it will be 20. So I will make all these equal first. Say equal and now I will give my dimension 20
Now we have made the 4 cuts. Now we will come out of the sketch. Close it and go to the tree view, select sketch and go for the cut
And here say through all or you can select the up to face. This is on the bottom side. Say ok. Now I switch to the isometric view. So here we have adapted the 4 cutouts
Now here is the radius R5. So we will give our radius. So I will select all the 4 edges. 1, 2 and 2 on the other side
Press the CTRL key to select all the 4 edges. Now I will select the fillet option and here I will give my fillet 5 and I will say ok
Now we have made this face and we have made the cutout and we have adapted the fillet. Now we will make the 4 flanges which is of the length of 50
So to make the flanges we will again switch to the sheet metal workbench and I will select this edge, this edge by pressing the CTRL key. Select this one and select this one
And here is the option of a flange. So you can see that flange has been made. Now we will customize it. So you can see that flange has been made but in the opposite direction
So click on the bend and here you will get options to reverse the flange. So here is the option of invert which is false. Make it true. So you can see that flange has been reversed as per our requirement
Now we will make our flange length. So length is here 10. So we will make it 50. And this radius, our sheet metal thickness is 2mm and internal radius is R2. So we will give here radius R2
So you can see that we have made this 4 flanges. Now we will make this cutout here at this location. And which is touching with our center line. And this cut depth is 28.29
Now we will make the other flange. I will select this face and again switch to the part design workbench and I will create on this face
So here I will draw a rectangle first. And then I will convert this face into the sketch entity. So I will select it and adjust it
Now I will select this point and this line and give point to line constraint. Similarly this point and this origin point and I will give the vertical constraint
This point and this point I will give horizontal constraint. Now we will find the cut depth. So cut depth is here is 26. So I will give my dimension 26
So I will select this line and give my dimension 26. And cut depth is 28.29. So I will close my sketch. And I will go to the tree view, select my sketch and click on the cut
And here I will give my dimension 28.29. Say OK. Now here is also radius R5. So I will select my radius by pressing the control key and give my radius R5
So here is the R5 radius has been adapted. Now we will make our flanks which is 36 in length and height is 18. Which we can see here 36 and 18. I will select this face and switch to the sheet metal and create a flank
You can see that flank tool is not active because here is a measuring tool has been active. So close it. And then select on the edge, create the flank. You can see that flank has been made but in opposite direction
So I will invert its direction. So invert fall. Make it 2. Length I want 18. I will give here 18. Radius is 1mm. I will make it 2. Now we will measure the length of our flank whether we have got this 36 length or not
So I will switch to the part design and here I will select the measuring tool. So this is the 40. So we will give the gap of 2mm on both the sides
So I will select my bank and here I will see the option of gap which is here. Gap 1 and gap 2. So gap 1 is for the left hand side and gap 2 is for the right hand side. So both the sides I will give 2mm
Now we will again cross check it. So I will go for measuring and I will select these 2 edges. So this is the 36 which is as per our requirement. I will close it
Now if you see this flank having the radius of R5. So I will select these 2 edges and click on the select and I will give here radius of 5. So you can see that it has been adjusted
Now we have a slot on this flank. So we will select this face and create a sketch. And we will project this edge, this one, this one and this one. And we will click on the slot tool and create a slot. And we will give the dimension
So before giving the dimension we will make a construction line. So for this I will select the line tool and I will draw a line and make it construction by selecting the line and clicking on this construction geometry
Now our total length is 36. So I will. So our total length is. So we will draw a construction line. We will select line tool. Make it vertical and we will select this line and click on this construction geometry
I will select these 2 points and give the dimension of 18 to make it at a center
And now this center line will help us to constrain the slot. So slot to slot center is 10 mm. So I will give 10. And from here to here it will be 5
Now from the top of the edge slot position is 8 mm. So I will select point and give it a vertical dimension of 8 mm. And radius R3.5
So you can see that slot has been constrained. Now I will switch to the isometric view. Come out of this sketch. Go to my preview, select this sketch and click on this cut icon
So we have successfully adapted the slot on this flange. Now we will give the radius on all these 4 flanges of R5. Which we can see here it is a typical radius
So for this I will select this edge, this edge, this edge, this one
And click on this select and give R5
Switch to the isometric. We have adapted all the features in our part. Now we will do the flat pattern of our part
To the flat pattern I will select on this my last flange and I will click on here unfold. And I will keep all the settings as default
So you can see that the flat pattern has been created and if we go in our tree so we can see that here is a unfold solid and here is a sketch
So now if we click on this unfold solid so we can see that it is not aligned with our sketch. So for this I will click on the transform and then I will rotate it by 90 degree
And I will say ok. Now you can see that my flattened solid is aligned with my sketch. And you can see that this flange will be flattened like this
And this face will be flattened like this. We can exactly imagine the unfolded projection in this model
Now here is a solid and 2D sketch. I can export this sketch into the 2D DXF. If I go to the export option and if I select here DXF I can select this DXF to export my sketch into the DXF format for the sheet metal cutting and bending
And I can also export this solid as a sketch file. So this is all about this session how to model sheet metal part in a FreeCAD. Thank you for watching
