Week 8 - Challenge 3 - Coin Holder Design

COIN HOLDER 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

• The tooling direction is used to find the direction in which the part is ejected out of the mold.
• First look at the part in all views and check which is the most appropriate direction for the tool axis.
• Then look at the angle between the vertical surface and y axis which may make problem during mold ejection.

• Since it is more than 3 degree we can take the tool axis along Y direction.

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.
