3D Printed Cutting Tool for Large Transmission Part | The Cool Parts Show Bonus

[@saml7610]

These tools are absolutely astounding. Really futuristic. I'm very impressed. Thank you guys so much for your awesome coverage. I don't work in the industry, but I am a passionate hobbyist, so I really love getting these looks behind the curtain when it comes to the stuff the big players are pulling off. Y'all are awesome.

Amazed at the visual similarity of these tools and aluminum casting of ant nests.

Man, this is indeed a cool part. Thanks for sharing!

I'm assuming the two spheres are for harmonic balance? Did they play around with the various GD struts to avoid resonant frequencies in the rest of the tool? Definitely a cool part!

[@KennametalInc]

Good eye! Yes, the spheres are balance features incorporated as a “balance by design” feature during simulation of the final design. These can also be used as a tool during the dynamic balancing of the tool after final assembly, as required. And finally, yes, organic structures such as this go through several design iterations to ensure the natural frequency of the resulting structure will avoid harmonics due to the forcing function during machining of the component.

I have some questions including the cost, as I can tell it was a metal 3D-printed part. What would be the effect of thermal expansion or cutting accuracy?

[@KennametalInc]

Temperature variation will have an effect on dimensional stability. We are able to simulate changes based on the coefficient of thermal expansion but as you might expect it is challenging to predict for complex shapes. As with other precise finishing applications, best practice will be followed to control temperature variations with the cutting conditions.

its definitely more than 50% of time saved

I feel tricked. It just runs regular inserts. A printed cutter it is not. It is an insert holder.
