Week 8 - Challenge 5 - Core & Cavity Design

AIM:-

To create a core, cavity, parting line and surface of a switch bezel.

PROCEDURE:-

Firstly, open the model using the open command.

TOOLING AXIS:

Create a point and insert a local axis system on it.

Create a line on the YZ surface by projecting the class-A surface on the sketch.

Similarly, create a line on the ZX surface by projecting the intersected class-A surface.

Now, create a bisect line using YZ and ZX lines and rename it as Tooling axis.

DRAFTING ANALYSIS:

After the Tooling axis is created, the Draft analysis is done on the surface.
Select the Elements as the Class A Model and the Direction as the Tooling Axis using the Compass option to define a new
the direction of the draft.
Click OK to check if all the surface comes under the within the limits of 0 to 3 degrees.
If the draft is more than 3 Degree then the surface will be shown as green.

CAVITY:

To create a cavity extract the Class-A surface and extrapolate it.

Now, trim Class-A surface with Class-C surface and with Class-B surface such that the hollow inside should be the output.

After that unhide the axis system and create a sketch in tooling direction using XY-plane.

Extrude the sketch by selecting tooling axis as direction.

Then trim it with the output and extract the boundary to create a closed surface using fill option.

Join the fill extracted surface with the output.

Now, Goto Part design and select Closed solid command to create a solid body.

Final Cavity output:

CORE:

To create a core, Extrude the sketch which was previously created along with the tooling direction.

Then trim the Class-B surface with extruding.

After trimming, extract the boundary and fill it using fill command.

Join the extracted filled surface with the extruded Class-B surface.

Now, Goto Part design and select Closed solid command to create a solid body.

FINAL CORE OUTPUTS:

PARTING LINE:

To create a parting line, Intersect the join of Class-A and Class-C surfaces with Class-B surface.

PARTING SURFACE:

To create a parting surface, split the Class-B surface with the parting line.

FINAL OUTPUT:

Goto Part design and use translate command to move the core and cavity.
