hello friends welcome to free cat tutorial and in this tutorial we will
0:05
learn the group feature in free cat you can also visit my website macnexus.com
0:12
where I write articles and tutorials on free cat you can download my tutorial
0:19
source file from the here if you like my method of teaching then please support
0:25
me on coffee.com you can buy me a cup of coffee your small support will help these channels to
0:33
grow and it will motivate me to create more awesome content on free cad i will provide my
0:40
website and my ko-fi donation page link in a video descriptions so let's come back to our tutorial
0:48
So basically Grootool in a FreeCAD is a tool to revolve or sketch or profile about an axis
0:57
cutting out the material from the supports. So Grootool is a very similar to the revolve tool
1:03
in FreeCAD. The difference is that Grootools used for to remove the material. If you see
1:10
this sketch so here B is axis A is the profile and this profile A revolves with respect to the this axis B and material got removed so let see with the example so here I have activated the part design workbench now I will
1:34
create a file I insert a body and on my origin plane now I will select this yz
1:44
plane and create a sketch I will off my origin plane and now I will create a
1:54
rectangle and let's give the dimension select the horizontal dimension of 300
2:03
and this vertical dimension of ETMM and come out of the sketch click on isometric
2:21
and now first we will revolve it we will select the reference
2:35
let's close it and where is our sketch yes here is our sketch we will on our
2:43
plane now we will select the sketch click on the revolve tool and from here we will select our reference so I will around this y axis and click on ok now I will off my origin plane switch to the right side
3:01
view and now here for example I wanted to insert external retaining ring also
3:11
known as a circlip so for this I will on my origin plane and I will select this
3:18
YZ plane and create a sketch and I create a rectangle
3:36
I will switch to the wireframe and let's give some random dimensions to it say horizontal 50 mm vertical vertical 50 mm
4:01
just approximate and give this horizontal dimension of 50 and this vertical dimension of let say 50 now we will close our sketch switch to the flatline views and
4:26
off our origin plane and now we will remove the material with the help of a
4:32
groove tool we will select the sketch and click on the groove so here free CAD
4:40
has took this z axis so I will select it and click on the y axis so you can see that a
4:48
groove has been created here. Let's modify the profile of the groove
4:56
I let's make it to the 30 mm and this is a 60 and close it
5:16
So you can see that groove profile has been modified. So this is the material removal operations to remove the material with the help of a
5:29
groove tool. This revolve tool and groove tools are very similar. This is the material addition process where groove is a material removal process
5:39
So this is all about this tutorial. Thank you for watching and thank you for your valuable time
