Week 7 Challenge - Assembly Workbench
AIM: Create assemblies of model 1 & 2 by the use of individual part files.
Objective: In this project we have to developed individual part files and then assemble all the part file into one assembly file in CATIA V5. Also create 2D drawing sheet of that part and product file.
Procedure:
- Open CATIA V5 software and go to File-New-Part (For individual part file).
- Create a point at the center axis with co-ordinates x=0,y=0,z=0.
- Go to Toolbar-Insert-Sketcher-Positioned sketch.
- In Sketcher Positioning select yz-plane and in projecting point select center point of the origin.
- Sketch the geometry with Profile toolbar.
- Check for Sketch solving statues it should be iso-constrained.
- Now check for Sketch Analysis.There should be no warrning and any sign of errors.
- Save the geometry by going to File-Save As with approprite name.
- Now create a product file through File-New-product (For making assembly of part file).
- Import all the part file into a product file.
- Save the file by going to File-save as with appropriate name.

BODY 4:
- Opening New Part for Body 4 Point Creation
Sketcher Workbench:
- Sketch for Base section (Body 4):
Sketch 1
Pad the sketch upto 6mm
Sketch 2
pad the sketch 2 upto 16mm from base
Body 4
BODY 5:
- Opening New Part for Body 5 Point Creation
Sketcher Workbench:
- Sketch for Base section (Body 5):
Pad it upto 50mm by using pad tool
Body 5
Here we see in above figure all the part of QUICK RETURN MECHANISM are drawn. Now we have to assemble all the parts into a product file for making assembly in assembly workbench.
- Create a product file
- Import all the part file into a product file by simply copy paste or existing component
Importing part file into a product file
Now to adjust all the part according to required mechaism but before going to this first create a new part and publish all the plane and point and make it a parent part body.
Publishing plane and point of parent part
Explode all the part
NOTE: Create axis along with required mechanism and publish all the axis, point
Now move to the assemblies of part
- By the use of constraint toolbar fit all the part into one product assembly
- Use coincidence constraint, contact constrain, fix constraint and offset constraint
- Hide all the part except required working part body
By the use of coincedence tool, coincide skeleton reference and body 1
Now coincide body part 2 with body part 1, give contact constraint and fixed the part body 2
Adjust body 3 along with body 1 by the use of coincidence constraint and manipulation tool
Adjust body 4 along with body 3 by the use of coincidence constraint and contact constraint
Use manupulation command to adjust according to the mechanism
Adjust body 5 along with body 1 by the use of coincidence constraint and body 5 with body 4 according to the mechanism

DRAWING2�������2
BODY 1:
- Opening New Part for Body 1 Point Creation
Sketcher Workbench:
- Sketch for Base section (Body 1):
Sketch 1 (yz axis)
Sketch 2 (zx axis)
Padding upto 100 mm each circular base sketch and then add to the part body
By using edge fillet tool fill the 5mm radius at corner of the centre
BODY 2:
- Opening New Part for Body 2 Point Creation
Sketcher Workbench:
- Sketch for Base section (Body 2):
Sketch 1
Here we create a new point 50mm in x-dirn from origin and create new plane along with new point and take yz plane as reference
Padd it upto 20mm forward
Sketch 2 (Connecting rod)
50mm distance between origine and newly plane
Pad it upto 15mm and take mirror image to make it upto 30mm
Sketch 3
Create a new zeometry for pocketing
Pad it upto 17.5mm according to the dimension
By adding and removing we can get appropriate body and then apply edge fillet to fill all the edges
Take mirror of whole body along with yz plane
Update edge fillet of connecting rod
BODY 3:
- Opening New Part for Body 3 Point Creation
Sketcher Workbench:
- Sketch for Base section (Body 3):
Sketch 1
Pad it upto 15mm according to the dimension given
Sketch 2
Create a new point and new plane
Sketch 3
Pad it upto 15mm
Sketch 4
Pocket it upto 7mm
Now add whole part into partbody and take mirror image
Add fillets according to the dimension like 2mm and 10mm
Here we see in above figure all the part of CV JOINT are drawn. Now we have to assemble all the parts into a product file for making assembly in assembly workbench.
- Create a product file and rename product
- Import all the part file into a product file by simply copy paste or existing component
Importing part file into a product file
Now to adjust all the part according to required mechaism but before going to this first create a new part and publish all the plane and point and make it a parent part body.
Publishing plane and point of parent part
Explode all the part
NOTE:
Create axis along with required mechanism and publish all the axis and point.
Add one more body 1 in product file
Now jump to the assemblies of part
- By the use of constraint toolbar fit all the part into one product assembly
- Use coincidence constraint, contact constrain, fix constraint and offset constraint
- Hide all the part except required working part body
By the use of coincedence tool, coincide skeleton reference and body 2 and also fix this body
Adjust body 1.1 along with body 2 by the use of coincidence constraint, contact constraint and manipulation tool
Adjust body 1.2 along with body 2 by the use of coincidence constraint, contact constraint and manipulation tool
Adjust body 3.1 along with body 1.1 by the use of coincidence constraint, contact constraint and manipulation tool
Adjust body 3.2 along with body 3.2 by the use of coincidence constraint, contact constraint and manipulation tool
