Week 9 - Attachment Feature Creation - Challenge 2

DOOR TRIM ATTACHMENT OF DOG HOUSE

AIM:

To create a dog house in door trim considering the design rule.

DESIGN PROCESS:

1. Class A surface
2. Tooling axis
3. Class B surface
4. Class C surface
5. Making a surface modeling
6. Making a solid modeling
7. Draft analysis
8. Making dog house

INTRODUCTION:

CLASS A SURFACE:

• Class A suface is the aesthetic surface it is top surface of the component.
• Class A surface is created by stylish team using ALIAS software.
• It's the input of plastic designer to create plastic component.

TOOLING AXIS:

• Tooling axis is ths importand features of the plastic component design ii will desides to open and close of core and cavity of machine.
• Before create a tooling axis has to analysis class A surface which is best place to located.
• After desiges the of tooling axis extract surface which the tooling axis place.
• Then create a point at the middle of the surface.
• From that point create a line then namded as tooling axis.

CLASS B SURFACE:

• Class B surface is the bottam surface of the component which engineering features are create from this surface.
• To create class B surface for that offset the class A surface at the 2.5mm in downwards direction.
• In offset surface has form a patch surface.
• From that surface has to make extrapolate the surface at the both end.
• After that trim the surface from the extrapolate surface.
• Then give the fillet to the edges then named has class B surface.

CLASS C SURFACE:

• Class A surface is act like a thickness of the class A and class B surface.
• In class C surface have to clear draft analysis for that use sweept command.
• Using the sweept command two method to create a class C surface.
• In sweept command in subtype obtion select the with draft direction give guide curve and give draft direction.
• While create C surface with draft direction method give angle of 3deg.
• Another method is with referance surface give guide curve and give referance surface.
• Using with referance surface method give angle of 93deg.
• To create C surface is be in two or more division.
• After that use join cammand join the division surface.

CONVERSION OF SURFACE MODELING:

• After creating the C surface use join command join the class A and class C surface.
• Then unhide the class B trim with class A and C.
• Then form a surface modeling of the door trim.

CONVERSION OF SOLID MODELING:

• After creating surface modeling then go to part workbench then use close surface select the surface give ok.
• Then created the solid features of door trim.

CREATION OF DOG HOUSE:

• Dog house is the engineering feature use for avoid shrinkage of the product and to attend the merging distance.
• For creating a dog house need to ask the molding engineer thay have to deside where the dog house to located.
• After that extract the surface were the dog house have to place.
• Then sketch the dog house and extrude the sketch.
• And go to part workbench give thicken to the surface at 2.5mm.
• After that give a draft at 2.5mm and give a minimum fillet of 0.25mm.

DRAFT ANGLE ANALYSIS:

FOR CLASS A SURFACE:

While doing draft angle analysis of class A surface marked area are not clearing so that stylish team have to improve the draft angle at minimum angle of 3deg.

FINAL PRODUCT:
