Week 9 - Project - A pillar Design with Master Section

AIM:

To Create the A pillar Design with Master Section.

OBJECTIVE:

• Ensure using surface command.
• Use closed body command to create the solids
• Rename geometrical set properly.

Output Required in a ppt :

• Picture of the sketches with Sketch solving status’s geometry tab
• Picture of the Detailed tree structure.
• Picture of the 3D CAD
• Create closed body
• Create tooling axis and follow design rules.
• Follow the Master section to create flange
• Follow the master section for thickness and to create the Closed volume.
• Follow master section to create Attachment features
• Tke thickness of Plastic to be 2.5 mm

SOFTWARE USED : CATIA

Let us look at how we have designed

INPUT:

CAD DATA is downloaded and Opened with CATIA.

TOOLING AXIS:

Tooling axis is defined as such all the features of the part can be manufactured easily. so here we followed the below steps to create the tooling axis.

• Two lines are drawn on the master section
• A point is also created
• Both the lines are taken for bisecting and getting the Tooling Axis
• Hence we get the Tooling Axis

Side Core Axis Also created

DRAFT ANALYSIS:

• Draft is done on the Class A surface.
• Change it to material in customise view.
• Click the Draft analysis tool and click the surface and align the compass to tooling axis.
• 3 degree is the clearing angle
• So here is photo of cleared (Green) draft.

B SURFACE:

• B surface is created by using the given Class A surface.
• Apart complicated face join other faces.
• Offset it to 2.5mm beneath the Class A.
• Create boundry and Create MSS, Extrapolate for the rest of the sections.
• Trim the extrapolates and join if needed.
• Hence we have created the B surface.

C SURFACE:

• The outer edge of the Class A surface is taken as reference boundry.
• Sweep is made with reference to tooling axis with draft.
• Join the sections and create the C Surface.

FINAL TRIM:

• Join A and C surface.
• Trim with the B surface.

• Closed Body is created

Master Section:

• Master section is used to create the Sketches
• It is then extracted and pad in part design
• Thicken, split are also used
• Reference photo is used to give fillets and holes

NOTE : Dimensions are different in reference drawing and Master section. But the mentor (rooban) said to follow the master section dimenson and hole diameter as in reference drawing.

DRAFT ANALYSIS:

• Draft is done on the Class A surface.
• Change it to material in customise view.
• Click the Draft analysis tool and click the surface and align the compass to tooling axis.
• 3 degree is the clearing angle
• So here is photo of cleared (Green) draft.

NOTE: Side drafts are not cleared and as discussed with the mentor (rooban) he said that Class A is defective. So Kindly consider

Here are few photos of the model
