Week 10 - Challenge 3 - Door Trim Lower with Engineering Features
AIM: To Create the Door Trim Lower Plastic component through the given Class-A surface.
Draft analysis: Draft analysis refers to the evaluation and examination of designs or technical drawings to assess their suitability for manufacturing or construction purposes. It involves analyzing the dimensions, tolerances, geometry, and other specifications of a design to ensure its functionality, manufacturability, and adherence to industry standards.
To evaluate the component, we must follow the below steps.
Step 1:
- Verify the Connectivity of the Class A Surface to Make sure there are no gaps between the components by using the join command.
- Perform a visual inspection or click on the boundary command and obtain the boundary lines of the component.
In our case, the component consists of two boundaries, one outer boundary and another cut section. As a result, the initial check has been completed.
Step 2:
- Determine the Tooling Axis of the Component The tooling axis refers to the direction in which the mold or cavity opens.
- Evaluate visually to identify the most suitable tooling axis.
- Examine all three axes.
After examining all three axis we can say that y - axis emerges as tooling axis for 3 Degree Draft.
To create the engineering feature such as stakes and locaters the draft angle of 0.5 Degree is used as the standard value.
Step 3:
- Create the tooling axis along the y-axis.
- Perform a Draft analysis using the Featured Draft Analysis tool in the software.
- Open the draft analysis toolbox.
- Locate the compass tool and place it aligned with the tooling axis.
- Align the compass precisely and click on the lock symbol to secure its position.
- Click on the surface you want to analyze or apply the draft to.
In this challenge bisecting method is not used to create the tooling axis.
EXPLANATION OF BISECTING METHOD:
- Bisecting method is used to find the proper tooling axis using the dummy tooling axis.
- In Bisecting method, the bisecting line is used which either bisects the two lines or it will show an error which means the two lines are parallel to each other.
- To determine the tolerability of a specific surface, we intersect it with the respective plane, resulting in a sketch consisting of two lines.
- Using the bisecting line option, we then bisect the line, creating a line at the midpoint between the two lines. This process helps us assess whether the surface is tolerable or not.
- Similarly, we create tooling clearing axes for both the x and y directions. These axes are then utilized to establish the main tooling axis by employing the bisecting line option within the line command.
DRAFT ANALYSIS
1. CLASS A SURFACE - DRAFT ANGLE 3 DEGREE


2. FINAL PRODUCT - DRAFT ANGLE - 3 DEGREE (EXCEPT LOCATORS AND HEAT STAKES)


3. HEAT STAKES AND LOCATORS - DRAFT ANGLE 0.5 DEGREE

CONCLUSION:
Thus, the part can be created using the Class A Surface provided by the styling team, with a draft angle of 3 degrees for the designed component. A draft angle of 0.5 degrees is used to create the necessary engineering features such as Heat Stakes and Locators.
