Week 11 - Project - A pillar Design with Master Section

DRAFT ANALYSIS ON CLASS A SURFACE

The draft analysis check is performed on the surface is to check wheather it satisfies the min draft angle as per the standards, the draft analysis on class A surface is doing before the creation of solid is to check whether the class A is drafted properly or not..The draft analysis is first done on the given class a surface with respect to the tooling axis , in that analysis the class A surface is cleared the min draft angle of 3 deg as shown in the fig.

TOOLING AXIS :

This challenge i using bisecting line method to create the TOOLING axis to clear the final output and we perform inside of dog house anlso we need to clear with draft analysis by using side core axis.

Class B Surface:

To create the class B surface initially, I measured the thickness of the master section (2.5mm). I offset the class A surface 2.5mm to the inside direction. The styling fillets on the class A surface are not offset properly, it created the patch on the offset surface. I used the sweep command to close the patch on the offset surface.

Offset patch:

I extracted the edges of the patches, to give as a sweep command's guide curves to close the patch.

Class C Surface Creation:

To order to create the class C surface, I used the sweep command. I sweep the class A surface edges along with referencing the surface for 4mm inside with 90deg. After the creation of the class C surface, the surface edges are needed to be extrapolated to intersect properly from all 4 sides. I trim the surfaces which extrapolated, to get the closed class C surface. I joined the class A surface and Class C surface to get a single surface of class A+C surfaces. I trim the Class B surface with class A+C surface join, to get the closed surface to create the solid body.

Solid part Body Creation:

To create the solid part body, I used closed surface command in the part-workbench. I gave the closed surface as an input in the closed surface command.

Dog House Creation:

• To create the dog house on the B-side, I extracted the lines on the master section and I create a plane to extract the lines concerning the master section.
• I extracted the faces which are required to create the shell for the dog house, and I trim the surfaces with each other as per the master section dimensions.

• I created the side core access, by creating a line at the centre of the back surface by creating the point.
• I thicken the shell for mm to inside. After thickening the surface, I gave deg draft to inner surfaces of the dog house.
• Now we need to give the bottom cutout for the dog house. To give the bottom cutout, I extracted the surface and offset it to 1mm outside (the bottom cutout should be 40% of the thickness of the dog house). I extract the upper surface of the dog house and offset it to 17mm bottom direction, to trim with the offset of the inner surface.
• After trimming the bottom cutout surface, I split the surface from the solid shell of the dog house. I gave a 0.5deg draft angle to the bottom area concerning to the side core axis.
• I created the rib base and ribs concerning the master section dimensions, and I gave a 0.5deg draft angle to the rib base and ribs. After drafting the rib base, I added the rib base and ribs to the dog house shell to make a single body.
• I created a sketch for the top cutout on the dog house, and I pad the sketch to the downside and removed it from the dog house part body.

Dog house top cutout sketch:

• I added the dog house to the main part body of A pillar solid.
