Week 8 - Challenge 3 - Switch Bezel Design

SWITCH BEZEL DESIGN USING CLASS A SURFACE

GIVEN SURFACE:

TOOLING AXIS:

        Tooling Axis is the tool travel direction. here the core gets along the axis of the tool travel. Hence creating a tooling axis is most important and first process for making a plastic part.

        To Create a Tooling Axis, We have to first verify which direction is best suitable for the tool to produce the part in an efficient way. This can be usually done by just assuming the direction by examining the given surface.

PROCEDURE:

        First, a point is crated and an axis system is placed at the point. Then a intersection line with respect to YZ plane is made using surface as reference. The orange dotted line is the intersection line along YZ plane shown below.

    Now two lines were created for creating a bisecting line (Orange line) as shown.

Now, we have to create another line for bisecting for getting the required Tooling Axis.

Since we have one face on the other side, it creates only one intersection line, hence we create a line using sketch giving an angle more than 6 in order to pass the draft analysis.

After we create bisecting lines from those two already created lnes and hence create the tooling axis out of it (black dotted line)

DRAFT ANALYSIS:

        Draft Analysis is a process to check the eligibility of the designed product to be manufactured without getting damaged. To get successful draft analysis, the part should have a draft of minimum 0.5 to 3 Degree. This draft should be in reference with the tooling direction of the core and cavity during molding process.

Draft Analysis of Switch Bezel CLASS A:

COLOR SCALE VARIANT:

GREEN : More than 3 Degrees.

RED : Between 0 to 3 Degrees.

BLUE : Less than 0 Degrees.

        As the color scale represents, The given surface has minimum 3 deg draft with respect to the tooling axis created. Hence this surface is now ready for part design.

DRAFT ANALYSIS OF SWITCH BEZEL PART:

    Since the draft analysis of the part also satisfies, this design is ready to be manufactured.
