Hello friends Welcome To freet tutorial
0:03
and uh in this tutorial we will
0:06
model this uh gripper Rod Center in
0:09
freead as you can see that uh I have
0:12
already model it and I will show you
0:14
from the scratch how you can do the same
0:16
in a freead with the help of a part
0:19
design workbench so let's start our
0:26
tutorial so here I will create a new
0:29
file and I have already activated the
0:31
part design
0:32
workbench I will create a body and uh I
0:36
will on my origin
0:38
plane
0:40
so if we see our part so we will see our
0:45
part from these directions so we will
0:48
draw this front
0:50
view on our exit
0:55
plane and after that we will create rest
1:00
of the features and uh we will try to
1:03
make part symmetric as much as possible
1:07
because when you make the part symmetric
1:10
then it is very easy to edit the part so
1:14
we will select this exit plane and
1:17
create a
1:20
sketch and I will off the origin
1:25
plane now you are seeing here a blue
1:28
tick on the sketch so click on the
1:30
recompute or refresh or you can also
1:33
press the F5 from your
1:36
keyboard and
1:39
now we will draw the
1:43
profile this
1:46
one this
1:48
profile so let's start our
1:55
sketching so while making our first
1:58
sketch entity we will will keep our
2:01
Center here means we will draw this
2:04
diameter at our origin so first I will
2:09
uh select a
2:10
circle and I will draw the two
2:14
diameter and here is outer diameter is a
2:18
41 so I will select it and click on
2:22
diameter constraint and I will give
2:25
Dimension
2:28
41 so that is the outer one and I will
2:31
drag circle to the
2:33
inside select this diameter and give it
2:42
28.57 which you can see
2:47
here and
2:50
now we will draw the other boundaries of
2:54
this part so I will first select the
2:57
polyline
2:58
tool
3:02
and I will draw the rough
3:14
profile so we have created the profile
3:18
and now we will uh give the dimension so
3:21
if you see here from Center to bottom is
3:24
a 44 so I will select this uh center of
3:27
the circle and this point and give the
3:30
vertical dimension of a
3:36
44 total length is a 121 so I will
3:41
select it and give it
3:47
121 and the height is a 48 so I will
3:51
select this line and give the vertical
3:54
dimension of
3:58
48
4:01
this one is a
4:08
41 and now this uh angle is a
4:14
120 so I will select this and this and
4:18
give the angular
4:21
Dimension
4:26
120 because here is angle given is a 30°
4:29
and from here it will be the
4:34
perpendicular so this is the
4:36
perpendicular this is a 90 + 30 that is
4:39
the
4:44
120 so here we have given the
4:50
dimension but still our sketch is
4:53
unconstrained so we will fix this
4:55
one so if you see here we can see here
4:59
the 12 mm Dimension is given from the
5:02
center of the circle to the outer edge
5:05
so I will select this point and my
5:07
circle point and give the horizontal
5:10
dimension of a 12
5:22
mm and now if you see our sketch so
5:25
bottom of the phas to the this phase is
5:28
29 m m m so I will select this and this
5:33
and give the vertical dimension of a 29
5:37
mm now you can see that we have a fully
5:40
constrain our
5:43
sketch we have a fully constrain sketch
5:47
but here we can see that we have the two
5:50
boundaries so it will create a problem
5:53
in Extrusion so we have a one boundary
5:56
here and uh we have one boundary
6:01
here so that will create a issue in
6:05
Extrusion so for
6:08
this we can trim it or we can make it a
6:12
construction and create a three-point
6:14
Arc so better way would be to trim it so
6:19
I will use the trim tool and trim it and
6:22
now I will uh close my
6:25
sketch and click on the pad in pad we
6:29
can and see here our Extrusion length is
6:33
a 32 so we will consider the maximum
6:37
material in a Extrusion and we will
6:40
create this pad letterer so here I will
6:44
give the 32
6:46
mm and from here I will check to the
6:49
symmetric to the
6:52
plane and I will click okay so we have
6:55
made our first base feature and now we
6:59
will
7:00
move to the next features and we will
7:02
read our drawing and sketch
7:05
it our next feature will be the this
7:10
feature so for this I will on my origin
7:14
plane and I will use my mid plane exit
7:18
to create our
7:19
sketch I will select the plane and
7:22
create a
7:26
sketch and for better visibility I will
7:29
will switch to the
7:31
wireframe and now I will project this
7:35
outer Arc so I will click on the project
7:39
external geometry and project it and now
7:43
I will uh use the polyline
7:47
tool to create a rough profile and then
7:51
we will constrain
7:58
it
8:05
so we have created the rough sketch now
8:07
we will constrain it we will select this
8:10
point and this Arc constrain
8:15
it this point and this
8:18
Arc constrain it and now we will uh view
8:22
the
8:24
dimensions so if you see the
8:28
drawings
8:29
so this is the 28 so I will select this
8:32
and give my Dimension
8:39
28 I will move it down and this is the
8:47
13
8:48
13 and uh I can move it to the
8:55
down this is the 14 this line so I will
8:59
select it and give the vertical
9:01
dimension of a
9:05
14 and we can see here 51 Dimension
9:09
outer is to the center so I will select
9:12
this point and the projected Arc point
9:16
and give it a
9:19
51 and I move my
9:28
dimensions
9:32
and this angle is a 14° which we can see
9:37
here so for this I will project this
9:40
bottom
9:43
h i will select this and
9:46
this and give the angle of
9:55
14 now if you see here this l line is
10:01
a in a vertical relation with a
10:05
center so I will select this point and
10:09
this point and add the vertical
10:12
relation so you can see that uh our
10:15
sketch is a fully constraint but our
10:18
profile is not
10:20
closed which means that we will create a
10:22
three-point
10:24
Arc so I will select the three-point Arc
10:28
select this point point and uh this
10:34
point and here I will uh select my arc
10:41
Center and my origin point and click on
10:44
the merge so you can see that we have a
10:48
fully constrained
10:51
sketch we will come out of the sketch
10:54
and from here we'll switch to the flat
10:56
lines now if you see our profile we have
11:00
the
11:01
Extrusion length of a 20 mm so we will
11:04
click on the pad and give the 20 mm
11:09
Dimension and from here we will click on
11:13
symmetric to the plane and say
11:16
okay now we will move to the next
11:19
feature and draw
11:21
it our next feature will be this pad we
11:27
will select this uh
11:29
bottom phase and create our
11:32
sketch and from here I will switch to
11:35
the
11:37
isometric so now first we will project
11:40
this age so we will click on the project
11:42
external geometry and select this
11:46
age and I will select the polyline tool
11:49
and create a rough
11:51
profile so this will be vertical and
11:55
horizontal and join with this
12:00
and from the orientation I will switch
12:05
to
12:07
the
12:08
bottom
12:12
face and I will select the line
12:15
tool and I close my
12:21
profile now I will switch to the
12:23
isometric and
12:25
uh I will uh
12:31
project this
12:34
line and I will switch to the
12:39
wireframe so this line will give me the
12:41
center in fact we have the AL origin
12:44
here so we will give the
12:47
dimension so if you see here from the
12:51
center of this whole to this age is a 26
12:56
so I will
12:57
select
13:00
this point and this origin point or AIS
13:04
and give the dimension of
13:07
uh
13:12
26 and this is also 26 so select this
13:16
line and give it a
13:21
26 this is the 16 mm which we can see
13:27
here
13:31
now I move the
13:40
dimension and this point to this
13:45
point let's switch to the top view
13:48
select this point and this point
13:51
distance 16 mm which we can see
13:57
here
14:01
now I will switch to the isometric so we
14:04
have a fully constrained sketch switch
14:07
to the flat
14:08
lines and come out of the sketch and
14:11
this uh Extrusion length will be the 16
14:19
mm click on the
14:21
pad so here we are not seeing anything
14:24
on the screen so simply click on the
14:27
reverse
14:29
and give the length of 16
14:34
mm click on the
14:39
okay now we will move to the next
14:43
feature our next feature will be this
14:48
pocket we will create this cut
14:54
here so for this we will select this top
14:57
plane and and create a
15:00
sketch switch to the
15:06
isometric now we will project our
15:10
geometry we require this geometry and
15:15
this
15:17
one now we will select the polyline tool
15:20
and we will create a rough
15:27
profile
15:44
we will switch to the
15:48
wireframe now we will add a horizontal
15:51
relation and now we will uh give the
15:54
dimensions so this will be the 10
15:57
mm
16:03
this will be the 6
16:16
mm this will be the
16:24
29 and this will be the 3 mm
16:37
so you can check all this Dimension
16:43
here if you read the drawing you can
16:45
find this Dimension so we have the here
16:48
profile and now I will close my sketch
16:52
switch to the flat
16:55
lines and now we will completely remove
16:59
the material from the top to bottom so
17:02
click on the pocket tool and click on
17:06
the through all and say
17:11
okay now our next feature is to create a
17:15
hole of a six drill 82° CSK to D
17:20
9 so for this we will select our back
17:25
pH and uh click on the sketch
17:29
switch to the isometric and we will
17:32
rotate our
17:39
model and now here we will uh create the
17:42
two
17:47
circles and now we will give the our
17:50
Dimensions so from this age to this
17:55
Center is a 22 so for this we will uh
17:58
click on Project geometry and we will
18:01
project it and before that we will add
18:04
the vertical
18:06
relation now select this point and this
18:09
point add a vertical dimension of
18:23
22 uh sorry uh this is the 13 mm so I
18:27
will edit it and
18:28
give the 13 Center to Center is a
18:44
22 and from the center to this hole is
18:50
a 92
18:53
mm so I will give the
18:57
92
18:59
and this circle and this circle will be
19:02
equal and I will give the it is a 6 mm
19:07
drill so I will give it diameter of
19:13
six so you can check these Dimensions
19:17
with respect to our drawing from here it
19:19
is a 13 22 and from this Center to this
19:23
hole is a
19:25
92 and now we will close our scale and
19:28
use the whole tool so select the sketch
19:32
and click on the whole tool so you will
19:35
see the whole parameter and now we will
19:39
give here the
19:41
CSK hole of a 6 mm drill of di 9 and
19:45
angle
19:47
82 now the next feature we will create
19:50
is a counter board hole which is uh
19:53
given here 12 deal 25 spot
19:57
face 2 mm
19:59
deep so we will uh select this pH and uh
20:03
create a
20:06
sketch and now we will uh click on the
20:09
circle and create a
20:12
diameter and here is a 12 mm drill so I
20:15
will select the circle and give the
20:18
diameter of a 12
20:21
mm and from the center it is a 38 so we
20:25
will project this age because it is our
20:29
at origin so I will click on the project
20:32
geometry and we will switch to the
20:36
wireframe and we will select the whole
20:39
circle and this ede and give it
20:42
dimension of
20:46
38 now come out of the sketch and from
20:50
here switch to the flat
20:53
lines now we will uh select our sketch
20:56
and click on the hole
20:59
so we have the hole and from here in a
21:03
drop- down hole cut we will select the
21:06
counter
21:10
board now we have a drill of a 12 mm so
21:13
we will give here the 12
21:15
mm depth we will keep the
21:20
25 and diameter will be the
21:24
25 and
21:27
depth
21:32
depth 2
21:35
mm so you can see that we have created a
21:38
12 mm
21:42
drill which is here uh depth we have
21:45
kept the through all or we can simply
21:47
say through
21:48
all diameter 25 and depth of a 2
21:54
mm so if you see here so this is the 12
21:58
mm
21:59
drill and this 25 belongs to the outer
22:03
diameter this outer diameter and the
22:07
depth depth is the this 2 mm this is how
22:10
to create the counter board in
22:13
freead now we will
22:15
uh say
22:19
okay now we will move to the next
22:23
feature our next feature is to create a
22:28
Central drill to das 6 draws 60 mm CSK
22:32
so here is also a CSK hole on this phas
22:37
so we will select this phas and uh
22:40
create a sketch
22:41
first and it is at the center of this
22:46
this our
22:48
Extrusion so we will simply select a
22:51
circle and create a
22:55
circle and we will give the
22:59
dimension so this is the 4 mm drill to
23:03
DIA 6 at
23:06
60° so we will select the diameter and
23:10
give it a 4
23:13
mm and we will close it and now we will
23:16
again use the whole
23:20
tool and first we will select the
23:23
counter sync from
23:26
here and our drill is a 4 mm and we will
23:31
keep the depth 25 mm so that it opens at
23:38
here diameter 6 and the angle we want is
23:42
uh
23:45
60° here is the angle is the
23:49
given and we will click on
23:54
okay and we will switch to the isometric
23:57
and you can see
23:59
that a counter sync hole is created as
24:03
per our drawing now we will move to the
24:06
next
24:07
tool our next feature is a mirror
24:11
feature so we can see that identical
24:13
looks on both the
24:16
side so we will uh press the space bar
24:20
and we will find out the pad so we will
24:25
if we click on the pad 01
24:28
so we do not see this pad if we click on
24:30
the pad 02 and press the space bar so we
24:35
will mirror it on the other
24:37
side so for this we will click on the
24:41
pad 002 and click on the mirror
24:46
tool and from here we will select the
24:50
reference and reference we will give the
24:53
X2 so you can see that uh feature is
24:57
created on the other side and we will
24:59
say
25:00
okay and
25:03
now we will switch to the
25:06
isometric and we will create our next
25:09
feature in the
25:10
drawing our next feature is to create a
25:14
six drill two holes on the both the pad
25:17
which we have mirror so for this we will
25:20
select the face and create a
25:24
sketch switch to the isometric and
25:27
switch to the top
25:30
view we will draw the two
25:33
circles so it is a flat drill so I'm
25:36
going to make with to the pocket
25:40
tool now we will give the
25:43
dimensions first we add the vertical
25:46
relation with these two
25:48
holes it is a 6 mm drill so both are the
25:52
equal so I will give the equal
25:56
constraint and and now we will give the
25:59
dimension which is of uh 48 from this
26:02
hole to this hole so I will select this
26:05
to Center Point and get add the vertical
26:08
dimension of
26:12
48 and I will switch to the
26:17
wireframe so we have the mid AIS so we
26:20
will use the symmetricity constraint
26:23
select this point this point and the
26:26
axis
26:29
and it is a 6mm drill so I will click on
26:31
the circle and give the diameter of uh
26:40
6mm and
26:42
uh our sketch is
26:45
unconstrained because it does not have
26:48
the vertical relation with
26:51
our this uh counter board hole so we
26:54
will click on the project geometry so
26:57
that we get a center now I will select
27:01
these two points and I add a vertical
27:04
relation and close
27:06
it and switch to the flat lines I will
27:10
simply select the sketch and click on
27:12
the pocket and from drop down I will
27:15
give the true all and say
27:18
okay as you can see that we have
27:21
completed our model and uh here is a
27:24
common note which is a round and fillet
27:27
of of R2 so you can give the fillet to
27:30
the allaround the part of R2 radius and
27:36
this is how we have a made gripper Rod
27:39
Center 3D model with respect to our
27:42
drawing in fread with the help of a part
