Week 8 - Challenge 2 - 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.

SOFTWARE USED

CATIA V5

DRAFT ANLAYSIS

Draft analysis in catia is a command that is used to detect if the part you drafted will be easily removed from the mold. it is performed based on color ranges identifying zones on the analyzed element.

Most of the industries is using minimum draft angle is 3 degree

PROCEDURE

• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft.

• After analyzing the above model the best tooling axis is z direction.

CREATING THE TOOLING AXIS

• Create a point 1 and insert a axis system on the point 1 as shown below

• Create a dummy tool axis on z direction using point – direction

• Create a intersection on ZY plane for the given surface

.

• Create a point to point line as shown below

• Add bisecting line as shown below by the reference of two lines created above and named as TOOLING AXIS

PERFORMING DRAFT ANALYSIS ON MODEL

• To perform draft analysis open customize view parameters and choose the material

• Insert a feature draft analysis by following these commands

I insert>analysis>feature draft analysis

• Align the compass on tooling axis that we created
• Open the color scale and enter the value is 3 deg.
• If the whole body is green that all the faces is greater angle than the provided angle

CONCLUSION

Thus the draft analysis on fan cover has been created using catia v5.
