How to engrave text on a curved surface

Article by GoEngineer on Jul 28, 2019

There are many occasions that will require engraving on curved surfaces and if you haven’t done it before it can be a bit confusing. We will go step by step on the process of creating a Curve Project feature.

  • Sketch Annotation
  • Curve Feature Selection
  • Add a Multi Surface Feature
  • Create Curve Project Feature
  • Add Engrave/Curve Feature

Sketch Annotation

To be able to use the feature, there must be a sketch that it can use. I have a sketched annotation that I want engraved named “GOENGINEER” below in Figure 1.

Curve Feature Selection

Now create a new 2.5 axis feature and select “Curve Feature” for the feature type, then select the sketch that you want engraved.  Note:  The End condition depth does not matter as it will be specified later. Figure 2 shows the 2.5 Axis Feature dialog box.

Add a Multi Surface Feature

Now that the Curve Feature has been created you will need to create a “Multi Surface Feature.” You can leave it on the default “Area Clearance, Pattern Project” strategy, then select the surface you want to engrave the sketch onto. Figure 3 shows the Multi Surface Feature dialog box.

Create Curve Project Feature

Now that you have a “Curve Feature” and a “Multi Surface Feature,” a “Curve Project” feature needs to be added. To do this, right click on the Multi Surface Feature > 3 Axis Mill Operations > Curve Project. Figure 4 displays the process.

You will then see a “Curve Project” feature in your “Operations” tab. Now right click on the “Curve Project” feature and select “Add Engrave/Curve Feature.” Figure 5 shows where the “Add Engrave/Curve Feature” is located.

A new window will appear prompting you to select which feature(s) you want to add to the Curve Project feature. Here you will select what features you want added. Select a feature, select “Add” then select “OK.” Figure 6 Shows the window that appears that you use to select the features you want to add to the Curve Project feature.

You now have created a “Curve Project” feature but there’s still some editing necessary. You need to edit the definition of the “Curve Project” feature and open the “Curve Project” tab. You will now set the depth of cut by entering an amount in the “Z Allowance” field under the “Surface finish” section. You can also use multiple passes and take a specified depth of cut per pass by changing the “Number of cuts” and entering the cut amount per pass in the “Axial offset” field in the “Axial offsetting” section. Figure 7 Shows the areas that need to be edited to get the correct amount and depth of cut.
