Week 8 - Challenge 3 - Coin Holder Design

OBJECTIVE

• To Create or Develop Class B and Class C Surfaces of Coin Holder from the given Class A Surface.
• To Determine the Tooling Axis for the component.
• To Analyse Coin Holder by featured Draft analysis in Catia V5

• Shown Screenshot is given Class A surface from the Design consideration team.From the surface create a centre point of the surface and add axis system from the point.
• Consider the possible axis for the component,i determine YZ axis. to create intersection of the surface in YZ axis.

• From the Intersection of the surface,Boundary of the surface create line of two inclined edges of the surface.
• From these two lines and centre point, Bisecting Line is created and define as a Tooling Axis.
• A line segment bisector divides the line segment into 2 equal parts. It passes through the midpoint of the line segment

Screenshot is shown Bisecting line or Tooling Axis

• From the created Tooling Axis, Considered Reference axis and Develop Class B and Class C Surfaces.
• Class A surface is customer View or Outer present of the component.
• Class B surface is Design Engineer view of creating Screw or Boss, Mounting Clip and Etc of the component.
• Class C Surface is Possible Draft of the component to Eject from the Core and Cavity (Draft angle is commonly in design consideration is 3 Degree)and Thicken of the component is 2.5mm.

Class_B Creation

• From the class A surface Extract Side Walls
• Extract Side Walls is Untrim and Extrapolate 10mm of each Walls
• Trim each Surfaces, of Side Walls
• Then Offset to 2.5mm, Because of Coin Holder thicken is 2.5mm
• After Offset,Fillet Each Edges of the surface. by Measure of Class A surface

Screenshot of Sidewalls

Base

• Extract Base of the Class A surface and Untrim the base
• ExtraPolate the base distance of 10mm (Point Continuity - Propagation)
• Offset the base through downward of 2.5mm
• Trim all Base surfaces

TOP WALLS

• Extract the arm rest from the Class A surface and Untrim
• Offset the arm rest surface inward Direction of 2.5mm.

Screenshot of Top Walls Surface

• Trim all Side walls, Base and TopWalls surface and Edge Fillets are created
• On Filleting the Class B surfaces, to considered the Thickness of the component 2.5mm

Outer Walls

Initial Trim

• Trim Outer Walls to (side walls,Base and Top walls of Trim) .
• Class B is created and Edge fillets all sides with consideration of Component Thickness of 2.5mm.

Class C Construction

• From the Class A surface, Create Boundary of the surface
• Then Extract Outer walls
• Then Using Sweep command, Create at Reference surface of (Extracted Outer Walls) and 90 degree to the ref.Surfaces at distance of 5mm

Final of Coin Holder Construction

• Join both Class A and Class C
• Then Trim both Join (Class A & C Surfaces) and Class B.
