Week 9 - Attachment Feature Creation - Challenge 2

Report:

Objective:

Is to design the Plastic model to pass the feasibility check to avoid manufacturing error.

Tooling Axis:

The tooling axis is created to show the tooling direction which shows the movement of the Mold and cavity & to exit the part without damaging the surface.

The tooling axis is created along the x-axis direction.

Draft Analysis:

Draft Analysis for Class A Surface:

• Click the draft analysis command in the analysis toolbar.
• Positioned the compass on the tooling axis.
• Activated the compass in the draft analysis dialogue box.
• Again repositioned the compass in the tooling axis.
• Clicked the Class A surface.
• Here green color is given for the surface clearing the draft angle of 2.9 and above.
• Here it is clear on all surfaces. there are no defects in the Class A surface.

Creating of Solid model:

Step 1:

Creating of Class B Surface:

• Class B surface is created for the given offset value of 2.5mm.

Step 2:

Creating of Class C surface:

The class c surface is created between the Class A & B surface. This surface act as connecting surface. Class C Surface is created from the Class A Surface using the sweep command with the reference surface option. Creating the Class C surface plays a major role which is created According to the draft angle to avoid the falling of the parting line in the Class A Surface. The C surface is created outward from the Class A surface.

According to the class C surface, the Class B surface is extrapolated to merge with the Class C surface.

Class C surface draft angle is given about 3 degree

1. Trim the class C surface to get the closed surface.
2. Class C Surface is Joined to the Class A surface.
3. Class A&C joint is trimed with the Class B surface.

Verified the final surface trim has any boundary or nor.

By taking the boundary command and select the model.

It shows the notification as - the selected body is closed, it has no boundary.

Step 3:

Creating of Solid model:

Switched to the part workbench.

Using the Close surface command the surface model is converted into a solid model.

Draft analysis is performed for the final solid model:

• Click the draft analysis command in the analysis toolbar.
• Positioned the compass on the tooling axis.
• Activated the compass in the draft analysis dialogue box.
• Again repositioned the compass in the tooling axis.
• Clicked the solid model.
• Here green color is given for the surface clearing the draft angle of 2.9 and above.
• Here it is clear on all surfaces.

Final Model with dog house:
