Week 8 - Challenge 3 - Switch Bezel Design

Objective:

To Create a Tooling Axis,Class B and Class C Surface with the help of Class A SURFACE of Switch Bezel Design.

Procedure:

Step-1: Creation of Tooling Axis:

• To create a proper tooling axis we should first identify which direction (ie. X,Y ,Z direction) is suitable for Tooling axis.
• Create a Geomentrical set for Tooling Axis creation.

Sketch-1 Creation

• By clicking on the Multiple Extract command on the base.Create a Point from where the tooling axis has to be consider.
• Create an Axis system on the point.
• Create a Position Sketch on YZ Plane - Projection point with reference Point - With V& H along proper directions.
• Create a Bisecting Line with the help of 2 lines created on the part.

Sketch-2 Creation

• Create a Position Sketch on ZX Plane - Projection point with reference Point - With V& H along proper directions.
• Create 1 line on the part and another line on the point with angle between two line as 3 degrees

Tooling Axis Creation

• With both lines created from Sketch-1 and Sketch-2.
• Create a Bisecting Line with the help of line command. By selecting Sketch-1+Sketch-2+Point-1.
• Press OK.
• Extend the Line to a certain distance which is visible.
• Rename the created line as TOOLING AXIS

Publication of Tooling AXIS

• Publication of tooling axis is done for easy accessibility.

Creation of CLASS B Surface:

• For creation of Class B surface
• Insert Geometrical sets for Switch Bezel Arm Rest,Walls,Base,Final Trims,Fillets
• By selecting each region Extract+Untrim+Extrampote+Offset for 3 mm
• Trim all the unwanted region to get the surface of Class B
• Measure the dimensions for all edges in Class A and apply the fillet values in Class B Surface.

Creation of Class C Surface:

• Select the edges that is needed for Class C Surface using Multiple extract along edges.
• Use smooth curve to reduces the points of the edges.
• Use sweep command to extend the surfaces.
• Extrapol the surface if its not getting intersected.
• Trim the unwanted surfaces.

Creation of Class A+Class C Surface:

• To create a Class A+Class C Surface use join command to join both surfaces.
• Updation of Class A surface is needed to trim along with Class C surface.
• After updating clear the unwanted edges using trim option.
