Week 8 - Challenge 3 - Coin Holder Design

Aim:

To create a solid Con Holder solid part by given Class A surface.

Report:

Class A Creation:

• First the given Class A surface are get organized as single class surface by trim commend.

Tooling Axis Creation and surface draft analysis

• After the Class A creation, point is created on the bottom of the surface. and a line is created on that point which is parallel to the side wall of the coin holder.
• Now insert the draft analysis tool bar to workbench and locate the compass on the tooling axis.
• then set the draft direction by with increase draft direction option.
• now check the draft angle with the input display.
• now the draft angle is checked for all the surface of the class A.

Class B Surface Creation:

• First the bottom surface of the coin holder is extract from the class A surface.
• This surface is got untrimmed and extrapolated to 10mm to point continuity.
• now these surfaces get offset to 2.5mm in reverse direction of the class A direction.
• then this surface got trimmed and named as Bottom surface.
• Now the side walls and chamfer get extract from the class A surface and offset to 2.5 mm.
• these surfaces get untrimmed and extrapolated.
• Now this surface is got trimmed.
• Now the top side wall and front wall surface get extract from class A Surface.
• The outside walls get offset to 2.5mm to the inside of the class A Surface. this surface is trimmed with the inner chamfer surface.
• now inner wall trim surface is trimmed with bottom Surface trimmed surface.
• then the outer surface is trimmed with the inner surface.

Class C Surface creation:

• the outer boundary of Class A is taken from Boundary Commend.
• The Adjacent walls to that boundary is Extracted from Class A.
• Now Sweep-->from Line-->with reference surface-->select the reference curve as the boundary-->ad set the sweep angle to 90 degree.
• the sweep length must to give 3 to 4mm. (Because if the length got to 6 to 10mm it will pop error while trim with surface B when Class C is joined to Class A.

Solid Forming:

• After the Class A, B and C surfaces are created, the class C is joined with Class A surface and formed as single form.
• Now this surface is get trimmed with the Class B surface.
• Now the closed surface is created.
• Open the Part workbench and select the close body option and select the final close surface.
• Now the complete close surface is formed.
• Now again insert the draft analysis and done the draft analysis to 3 degrees.

Draft and solid component:

Result:

Thus the task has been completed
