How Do You Cut Gear in SolidWorks?

by

Are you looking to learn how to cut gear in SolidWorks? Look no further! In this tutorial, we will guide you step-by-step on how to create a gear and then cut it using the powerful CAD software, SolidWorks.

Step 1: Creating a Gear

Before we can cut the gear, we first need to create it. To do this, follow these simple steps:

  1. Open SolidWorks: Launch the SolidWorks software on your computer.
  2. Create a New Part: Click on ‘File’ in the menu bar and select ‘New’ from the drop-down menu. Choose ‘Part’ and click ‘OK’.
  3. Select the Front Plane: In the FeatureManager Design Tree on the left-hand side, right-click on ‘Front Plane’ and select ‘Sketch’ from the context menu.
  4. Draw a Circle: Use the Sketch tools to draw a circle with the desired diameter for your gear. You can use dimensions or relations to define its size precisely.
  5. Add Teeth: Now it’s time to add teeth to our gear.

    Select the ‘Smart Dimension’ tool and add dimensions for one tooth’s width and height. Then use the ‘Linear Pattern’ tool to replicate these teeth around the circle.

  6. Create Extrusion: Once you are satisfied with your gear shape, exit the sketch by clicking on ‘Exit Sketch’. Now use the ‘Extruded Boss/Base’ tool to extrude your gear into a three-dimensional object.

Step 2: Cutting Gear

Cutting gears in SolidWorks is relatively straightforward. Follow these steps:

  1. Select the Gear: In the FeatureManager Design Tree, locate and select the gear you created in Step 1.
  2. Click on ‘Insert’ Tab: At the top of the SolidWorks window, click on the ‘Insert’ tab to access additional tools and features.
  3. Select ‘Cut’ Feature: In the ‘Features’ group, click on the ‘Cut’ icon to initiate the cutting operation.
  4. Select ‘Extruded Cut’: From the drop-down menu, choose ‘Extruded Cut’. This option allows you to cut through solid objects using a specified depth.
  5. Define Cutting Parameters: Now it’s time to define your cutting parameters.

    Select an appropriate plane or surface to define where you want your cut to occur. You can also set a specific cut depth if needed.

  6. Preview and Confirm: Review the preview of your cut operation. If everything looks good, click ‘OK’ to confirm and apply the cut to your gear model.

Tips for Cutting Gears in SolidWorks:

  • Avoid Overlapping Geometry: When creating gears with teeth, ensure that none of them overlap. Overlapping teeth can cause issues during cutting operations.
  • Add Fillets or Chamfers: To enhance your gear’s appearance and reduce sharp edges, consider adding fillets or chamfers after cutting.
  • Experiment with Different Tooth Profiles: SolidWorks allows you to create gears with various tooth profiles such as involute, cycloidal, or even custom ones. Don’t be afraid to experiment and explore different options.

With these simple steps, you can easily create and cut gears in SolidWorks. Remember to save your work regularly and practice using different gear configurations to expand your skills. Happy designing!
