Week 9 - Attachment Feature Creation - Challenge 2

DOG HOUSE DESIGN

CLASS A SURFACE

It is the surface which is given to the plastic designer as input.it is the outer most and aesthetic surface.

CLASS B SURFACE

A surface that is at a distance of thickness from class A surface is class B surface.all engineering features are contained in B surface.

CLASS C SURFACE

A surface that joints class A and class B is called C surface.

TOOLING AXIS

• First look at the part in all views and check which is the most appropriate direction for the tool axis.
• For this surface we can see that Y direction is suitable for tool axis since all parts can be seen from Y axis.
• Then we take intersection between the problem making surfaces and YZ plane.
• Then extend the lines of problem making surfaces.

• Then we take the bisecting between the extended lines to get the orginal tool axis.

 

• Then for side core ejection we make another tool axis along X axis.

DRAFT ANALYSIS

• Draft analysis is done to check whether the part designed is manufacturable or not.
• Minimum draft angle considered is 3*.
• For analysis goto insert >analysis >feature draft analysis.then place the compass on the tooling axis and click on the part.
