How to create a knurl texture

Objective:

Learn how to create a knurled texture.

Procedure:

1. Set up the faces and bodies

    • Start with any imported CAD Body
    • Select the faces for knurling and create a  CAD Face List Variable 
    • Convert the CAD bodies (main bodies and knurl body) to Implicit bodies by Implicit Body from CAD Body to be used in the last two steps

2. Create the lattice knurl pattern

    • Add a Conformal Lattice from CAD Face 
      • In the Reparameterize block, set the CAD Face: CAD Face List Variable
      • Origin Position: 0,0
    • Double-click in the Face Parameterization input and select Reparameterize CAD Face 
    • In the Conformal Lattice from CAD Face block, set the Unit Type: Square honeycomb Rotated
    • UVW divisions: 15, 15, 5
    • Offset distance: -0.1 mm (a negative offset distance will move inward, while a positive offset distance will move outward)

3. Thicken the lattice

    • Add a Thicken Body (the thickness will define the width of the knurl grooves)
      • Body: Conformal Lattice from CAD Face
      • Thickness: 0.001 mm
    • Boolean Union the Thicken Body to convert from a list to a single body
      • Blend Radius: 0 mm

4. Create the Knurl Texture

    • Boolean Subtract the thickened lattice from the knurl section. This will cut into the surface and create the knurling texture
      • Blend Type: Chamfered
      • Blend Radius: 0.125 mm
      • Primary Body: Implicit Knurl Body (from setting up the faces and bodies)
      • Subtraction Body: Boolean Union (from creating the Knurl Pattern)
