Week 8 - Challenge 4 - Coin Holder Design

AIM:

To Create the Coin Holder Plastic component through the given Class-A surface and 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 performing the Draft analysis on the model.

PROCEDURE:

• It is a Coin holder that we are going to check the draft angle on this product.
• Initially the connectivity of the class A product should be check by using join and it has ensured that no suface gap inbetween it, it can also be checked in visual.
• By using the boundary option the boundry line will be created around the surface of the product.
• Then it must be disassambled and the connectivity of the surface must be checked.
• Then in all directions that sholud be checked for the perfect tooling axis that in which direction the tooling axis is good to view.
• In this particular product Z would be the best possilble tooling axis.
• For creating a tooling axis the new geometrical set has to be created, in that geometrical set the origin point must be fixed initially then the axis system is placed on that origin point.
• Then by taking the ZX plane the intersection will be done with respect to the Coin holder and as a result there will two lines are projected the intersection line that is shown on the picture below.
• Before creating the original tooling axis the dummy tooling axis is created which is perendicular to the intersection line.
• The Bisecting line has to be created with the help of line command initially the point to point line is used to create two lines after that by using that two lines the bisecting line is also created by connecting the origin point.
• That bisecting line is Tooling axis for X direction and it is renamed as Tooling direction of X axis.
• It is the class A surface of the coin holder.

• The publication of the fan cover and tooling axis has to be done for the easy access.
• The tooling axis and coin holder is projected for viewing easily.
• Then opening the draft analysis tool bar which is in the Tools.
• In the draft analysis toolbar the campus symbol which is there has to be picked and then red point on the campus can be moved to the toolingaxis in the perfect alignment, that campus is used to denote the draft direction.
• The B surface that is created with respect to the A surface that is offseted to 2.5mm and in the fillet area it was offsetted by adding the radius of those fillets.
• The C surface will be projecting the boundary lines.
• By using that boundary lines the C surface will be created this can be trimmed by the B surface that already created.
• The C surface that are created on 2.5mm of height.
• C surface will be extruded inward upto 2.5mm with the draft angle of 3 degrees.
• Then C surface will be trimmed with respect to the B surface that is created.
• Picture of the coin holder all three surface is shown below.

• After that every surface should be joined by using join command.
• The surface that is created will be changed into part model for converting it into the closed part.
• So that there will not be any open area on the Coin holder.

Draft Analysis:

• Draft analysis is to evaluate or double check the part that we created.
• The making of a part which is molded.
• These kind of analysis will verify all the surfaces and whether it is suitable when we removing the part from the cavity.
• The Draft analysis if the Coin holder is shown below.

Tree structure:

RESULT:

Hence the Draft angle has been analysed on the Coin holder which can able to design.
