    Fractal in 3D CAD

    Cool! But I don't have the technology to read a floppy disk...

    Fractal in 3D CAD

    Thanks Greg, I was thinking something along the lines of the image below. It would certainly need to be generated by the equations, and not modeled piecewise... This is mostly a curiosity, a fun way to benchmark and compare systems...

    Fractal in 3D CAD

    I'm interested in making a fractal pattern in 3D CAD like ProE or Solidworks. Have any of you done this before? Would you be willing to share an example?

    Ra vs sandpaper grit size

    Thinking within the context of molding, I found a nice reference with SPI, RA, and sandpaper... http://www.balesmold.com/SPI.htm

    Ra vs sandpaper grit size

    Anyone know of a good reference correlating Ra with various sandpaper grit sizes?

    Roughness vs fracture toughness

    I'm looking for a correlation between surface roughness and fracture toughness of superelastic nitinol. I know fracture mechanics states that smoother surfaces will be stronger than rougher ones because there are less imperfections for cracks to nucleate from. It is also common practice to...

    Drilling PEEK

    Thanks for all the help! It looks like in our case it boils down to having a sharp drill bit. We're working with a carbide tool now, and getting better results. Stay tuned to see how much life it gives us. It hasn't become dull yet... Can anyone point me towards guideline for tip geometry vs...

    Drilling PEEK

    We're seeing a lot of tool wear using HSS jobber drills with TiN and Nitro-Carburized surface finishes to drill PEEK. What is the recommended drill for drilling 1.25mm diameter x 12mm deep holes in PEEK with maximum precision and minimum tool wear? I'm considering trying carbide, but haven't...
