How to create deep cutouts properly in SolidWorks

Introduction

Creating deep cutouts in SolidWorks can significantly enhance your design capabilities, allowing you to craft complex features that add both aesthetic appeal and functional value. Whether you’re designing mechanical parts, enclosures, or intricate components, understanding how to properly create deep cutouts ensures your models are accurate, manufacturable, and visually precise. In this comprehensive guide, we’ll walk through the step-by-step process of how to create deep cutouts properly in SolidWorks, providing practical tips, common pitfalls to avoid, and best practices to optimize your workflow.

Understanding Deep Cutouts in SolidWorks

Before jumping into the process, it’s important to understand what constitutes a deep cutout. In SolidWorks, a deep cutout involves removing material from a part to a significant depth—often more than half of the part’s thickness. This process is different from shallow cuts or extrusions because it often requires careful planning to ensure the structural integrity and manufacturability of the part.

Creating deep cutouts involves more than just a simple extrude cut; you need to consider factors like tool access, part stability, and proper feature management. Now, let’s delve into how to do it efficiently and correctly.

Step-by-step Guide to Creating Deep Cutouts in SolidWorks

1. Prepare Your Model

Start with an accurate sketch of the basic shape.
Ensure the material thickness is properly defined.
Add additional sketches or reference geometry if needed to guide your cutout placement.

2. Create the initial sketch for your cutout

Select the face or plane where you want to make the cutout.
Use sketch tools (Circle, Rectangle, Polygon, or custom shapes) to outline the cutout profile.
Fully define your sketch to avoid errors during feature creation.

3. Use the ‘Extruded Cut’ feature

Go to the Features tab and select “Extruded Cut.”
In the property manager, set the depth of cut to be greater than 50% of the material thickness to qualify as a deep cut.
Choose the appropriate end condition:
Blind: to specify an exact depth.
Through All: to cut through the entire part.
Use the “Flip Side” option if needed for complex geometries.

4. Adjust cut parameters for accuracy

For very deep cuts, consider using “Up To Next” or “Up To Surface” options.
Fine-tune the depth to avoid overcutting or undercutting.
For complex geometries, consider using the “Merge Result” option to keep the feature as a single entity.

5. Use ‘Cut-Extrude’ with guidelines for complex cutouts

When the cutout isn’t straight or involves contours, project edges or sketch guide curves.
Use “Offset Entities” if necessary to control the depth and shape of the cut.

6. Incorporate additional features if needed

For more intricate cutouts, combine “Cut-Extrude” with “Sweep” or “Loft”.
Utilize the “Shell” feature to hollow out sections before deep cutting.

7. Validate your cutout

Check the part visually and with section views.
Use measure tools to verify depth and dimensions.
Ensure no interference or structural issues are introduced.

Practical Examples of Deep Cutouts

Mechanical Enclosures: Hollowing out sections to save weight without compromising strength.

4. Validate Material Properties and Finishing Details

Correct material assignment impacts structural integrity and manufacturing processes.

Confirm each component has the correct material attribute assigned (e.g., Aluminum 6061, ABS).
If applicable, specify surface finishes or coatings within the material properties.
Use “Appearance” overrides to visualize final product looks for presentation purposes.

Remark:

Using accurate materials helps with simulations and cost estimates.

5. Perform Tolerance and Fit Analysis

Understanding clearances and fits ensures parts assemble correctly.

Input realistic manufacturing tolerances into your model.
Use “Design Validation” tools to simulate how parts will fit under different conditions.
Adjust dimensions if necessary to accommodate manufacturing tolerances.

Example:

A hole designed as 10 mm may require a 10.05 mm diameter to allow for proper fitting with a bolt.

6. Export for Manufacturing or Presentation

Once the model is verified, prepare suitable files.

Export your assembly as STEP (.stp) for CNC machining or 3D printing.
Generate detailed drawings with annotations for fabrication.
Use Fusion 360’s “Make” function for 3D printing or other manufacturing methods.
Ensure all necessary views, sections, and notes are included.

Tip:

Label parts clearly and include assembly instructions directly in the drawings.

7. Check for Version Control and Documentation

Maintain organized records of your design.

Save and name your latest version clearly (e.g., “V3.2_Final”).
Document any notes, changes, or design decisions.
Store project files in a version-controlled environment if possible.

Best practice:

This step simplifies revision tracking and future modifications.

Common Mistakes to Avoid During Final Checks

Overlooking small interferences that could cause assembly failure.
Ignoring material and finish specifications, leading to manufacturing errors.
Forgetting to test joint movement or clearance in assemblies.
Not validating dimensions against tolerances before exporting.
Rushing the final review, which can result in overlooked issues.

Pro Tips to Enhance Your Final Assembly Check

Use physical prototypes or 3D-printed models to verify fit before costly manufacturing.
UseFusion 360’s “Simulation” workspace to perform stress analysis.
Collaborate with team members for peer review.
Automate checks using scripts or add-ins for repetitive validation.
Keep detailed notes of any issues identified during review for future reference.
