Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)

AIM:

• To Create the Door Handle Component from the given Class-A surface.
• To Create the tooling axis for the given Class-A Surface meeting the requirements of the draft angle.
• To Attach B side Features in the component.
• To perform the Draft analysis on the model.

TOOLS USED:

• Boundary
• Join
• Multiple extract
• line
• Trim
• Surface offset
• Draft analysis
• Intersect
• Surface sweep
• Close body surface

DESCRIPTION:

1. CREATING TOOLING AXIS -

The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling Direction.

• Open the given CAT part file.

2. REPAIR CLASS A SURFACE

TO REPAIR THE ClASS A SURFACE to avoid the sharp edge on class a we are using the multisection , blend , extract boundary and then join mergeing distance 0.01mm

class b surface

if the b surface are offset form class a surface and the offset can done properly face are make patch in step by step process of using the multi section and blend tool to fix the patch on b surface and then extrapolted on side face of surface for using trim easilier

class c surface

• extract the boundary from the class A surface using boundary command.
• Using disassemble tool to divide the boundary as the boundary contains domains.
• Use sweep command > choose profile type line > subtype as with draft direction > choose guide curve and draft direction > draft angle as 3 degree > preview

DRAFT ANALYSIS

The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

• Before going to drat analysis go to customized view parameter >under mesh >check material and then click ok.
• Now for draft analyses go to insert » analysis » feature draft analysis.
• Use the compasss to define the draft direction.
• In the colour scale change the draft angle to 2 degree.
• The component changes to green in indication of passing draft angle.
• Use running point to check the angle on the component.
