Making a brass knob for a gas fireplace. The original knob was lost.
The machine toolpaths are not very fast or efficient. This was a one-off piece, so it was better to just make the part using the code I had, rather than spend more time tweaking the code in order to save a few minutes of machine time.
If I were doing a production run, it would definitely be worth spending time to make the toolpath code more efficient.
Off camera, the knob was cross drilled and tapped to accept a set screw, which holds the knob onto the shaft.

New guy on CNC machining at a conventional mill speed. That machine can do that in 1 minute.

You can make deeper and more aggressive cuts on brass. Saves time & money. But I get it, this is a demo and not production!

It seems like more than half the process is missing from the video. Did you cut it out on a lathe? Did you drill the grub screw hole by hand? How did you re align it to do the bevel on the bottom side?

Have to admit my heart skipped a beat when I saw his hand near a live spindle. Goes against what I learned, but I loved this video.

Am making a very similar part out of aluminum using a brother machine. 1/2" carbide end mill 9,000 rpm 110 inches per minute 0.200" depth per cut 0.800" total depth run time is approx 28 seconds.

What is that first tool? Superfly? Where do I get it?
@tacitus101010
@tacitus101010 7 лет назад
Yeah it's a Tormach SuperFly fly cutter. You can buy it directly from Tormach. Also Little Machine Shop stock Tormachstuff , but I don't know if they stock that tool specifically.

Hey Lee? This machine can make threads as well?
@makeandmachine7698
@makeandmachine7698 8 лет назад
+Ljudevit Binder Yes it can :) I like to use thread mills. I'll film that in the next couple of weeks.

Why not chamfer in one pass? Is this a desktop mill?
@makeandmachine7698
@makeandmachine7698 8 лет назад
It's a Tormach PCNC 1100 so definitely capable of chamfering in one pass. This was my first attempt at cutting brass so I wanted to take it easy and get the best possible finish. Being a one-off part it wasn't necessary to reduce machining time like it would be on a production run.

or you could by it on misumi for 1/10th of the price
@makeandmachine7698
@makeandmachine7698 7 лет назад
I didn't know about that site, looks great though. For me, it's usually more satisfying to make something than to buy it. The process itself is incredibly interesting, and an invaluable learning experience. Plus when you design something yourself you can get exactly what you want.
