Making stuffs at work

Material is .5"X2" hot rolled 1018 mild steel. Il the first operation is a helical cut down in to make a clearance hole. The second operation, the endmill spirals out in .05" steps to make a 1" hole. The third operation, it’s stepping over .05" at 130 Inches Per Minute. This operation follows the concept of Troichoidal milling. We don’t have any program to write the code to do this, so I figured it out myself. The fourth operation cleans the slot up.

I miss CNC and making stuff. Used to be tool path programmer now I put little boxes into big boxes at twice the pay. The world is a confusing place.

No coolant flood?

No, it’s not recommended. The coolant will actually increase tool wear because of thermal shock.

That’s what is recommended. You have to realize you are barely loading the tool because it’s not a full slot pass. You’re just skimming it.

Interesting. I only do design, I let the machinists handle the details and stay out of the way.
I would like to set up a hoppy CNC mill in my basement one day when I have enough $$ and my wife isn’t looking.

Gotcha. Looks cool too. It’s been over a decade since I was a machinist.

I highly recommend looking up troichoidal milling on YouTube. It’s insane to watch. What I am doing is mild compared to some of the videos on there.

Thanks will do.
