Week 8 - Challenge 1 - Base Bracket Design

Aim

Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Report of draft analysis

In a draft analysis we have to position the tool direction on surface class A and the compass should be lock in the tool direction and then check the analysis under running point should check the draft angel on the surface oh the class c

If the

red represent - no draft

Green represent - positive draft on cavity side

Blue represent - negative draft on core side

Please check the report in given below attached file for draft analysis

Procedure

• If the geometrical set has divided as per guide

• Class a surface
• Class b surface
  • Class b operation
  • Class b offset
  • Class b join
• Class c surface
  • Class c operation
  • Class c join
  • Trim ABC
• Toolingdirection
• Parting line

And then we start offset operation from the surface a to surface b

We have extract the rib surface we don’t select the

Tooling direction

We make a point & line in on the surface on the hole center for tooling direction

And the tooling direction depends upon the surface of draft angel given by as and then we move on the tooling direction

And the direction of compass should be an lock through the line along the surface

If the tooling direction to desired the cavity and core side of the surface

Surface A

Repair the class a surface there is a n number of surface we should be the join the all surface together in single surface

Surface b operation

1^st we start extract form the surface a and then offset 2.5mm from the class a toward the an z direction

And the we UN-trim tool to select this operation all the extract element should be an untrim, then extrapolate the UN-trim element to make a flat surface and then all other surface a should offset and the we make a trim on the surface

Once all the trim completed and move on to edge fillet

To find the fillet radius using measuring item and find the radius of the edge and we move on the surface is 2.5 mm.

if the radius 3 and offset distance is 2.5 mm and then total radius of fillet in b surface is 5.5 mm on the all sharp edge once all the process finish on b surface we move on surface c

Surface c operation

And then all operation completed in class a & b and the we make a boundary on class a surface and then the if there are three boundary present in the surface on A

each boundary should make an sweeps tool we use draft with direction and the draft angle is 3 degree

Once the all operation completed in the surface on c surface then we move on to final trim of class ABC

Final trim ABC

If all required position should be there and the and all the operation done on there surface.

And we check the draft analysis

If the draft analysis report is attached on above of the report please find it

Parting line

Parting line will come’s due to the desperation of core and cavity and the parting line has to identification by the system of to intersect the draft analysis of positive draft and negative draft

Once the all operation done on the surface moulding and we move on to part design and the part to should make as closed surafce tool make a solid component
