Week 9 - Project 1 - Door Applique Design with Engineering Features

AIM: Create the Heat Stakes and the locators considering the design rules for the door applique.

REPORT ON DRAFT ANALYSIS:

Given Class A Surface:

STEP 1: Check the connectivity of the Class A Surface

• Ensure that there is no gap between the component, using join command.
• We can visually check it or by clicking boundary command.
• It has double boundary.

STEP 2: Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens.

• Check visaully which is the best possible tooling axis.
• Check all three axis.
• Perpendicular to the base is the best possible tooling axis.

Creating a Tooling axis along perpendicular to base:

Therefore the main tooling axis is along perpendicular to base.

Now perform the Draft analysis using the Featured Draft Anal ysis tool in the tools.

Then after opening the draft analysis tool box go for the compass and place the compass alinged to tooling axis and click on the lock symbol after alinging and further click on the surface.

So the given Component qualifies the draft analysis.

Now Creating a solid by creating a CLASS B and CLASS C and closing the surface.

Now we create a sketch inorder to make a 4 way locator and pad it to the required length, draft it, fillet it and translate it to the required position.

Now we create a sketch inorder to make a 2 way locator and pad it to the required length, draft it, fillet it.

Now to create heat stake extract the boundary and use points and plane repetition and create points where heat stakes are needed and pad it, draft it, fillet it.

Now create clearence surface and provide 0.1 mm clearence for locators and 0.5 mm clearence for heat stakes.

DRAFT ANALYSIS ON THE COMPONENT:

EXPLANATION ON BISECTING METHOD:

Bisecting method is basically use to find the proper tooling axis using the dummy tooling axis. In Bisecting method, bisecting line is used which either bisect the two line or it will show error which means the two lines are parallel to each other. In order to know whether the particular surface is toolable or not we intersect the surface with the respective plane and get a sketch which consist of two lines and with the help of bisecting line option we bisect the line which creates a line at the mid point of the two lines. Like wise we create tooling clearing axis for x and y which will be used to create the main tooling axis using the bisecting line option in in the line comand.
