- Hello everyone, welcome to At-Man Unlimited. We have a machining job in the shop that the customer gave us permission to show and also shared some pictures. I’m also trying something new with overlaying a CAM simulation along with the machining footage. It does get out of sync because the simulation does not properly rapid vs feed when it moves. If people like this I will work on better syncing it up.
If you have any questions please feel free to comment or email me, AtManUnlimited@gmail.com

The inclusion of the simulation was a great idea Tim.
Thank you Ken, but I can't take the credit, a viewer had the idea, I just tried it. Had trouble keeping it in sync though because the simulation does not change rates based on feed vs rapid. I want to find a better simulation back plotter that accounts for both feed and rapid moves and then I think it will stay in sync better.
That was fun to watch, Tim. Nicely made part and seeing it in "use" is always a nice treat for both viewer and creator.
Best wishes,
Tom
Thanks Tom
This customer was a lot of fun to work with.
Tim
great vid
Thank you Billy
Nice job At-Man!
Thank you JP!
Cool vid!! I enjoyed it. I really liked the end where you showed it in use. :)
Thank you, yes, don't get to see parts in use very often.
Very Bob Ross.
Just need some happy little trees!

Maybe some opera next one?
Carmen maybe
I'm a traditionalist and prefer flood, but what can you say about this new method of just blowing the chips away with compressed air and maybee using a fine mist of lube, or maybee no lube atall ans a coated cutting tool??
Just interested in your opinion as it looks like your a flood man by choice
Hello Mike, I think the rumors of the demise of coolant are over blown. I almost always use flood coolant. There are some special cases where flood coolant is not good, specifically with coated carbide tooling. In this case the very edge of the tooling can get very hot in the cut and when it exits and hits the cold coolant the carbide can shatter at the edge. This typically happens when roughing harder materials at higher speeds. Also no coolant with ceramic tooling. As for mist coolant when it comes to larger machines, I feel it is the worst option. When using mist coolant you get a little bit of coolant on all the chips, this tends to make them stick to everything. If you watch some of the videos that use mist only you see two things, a build up of chips stuck all over everything, or someone standing at the machine trying to get the chips clear with another air nozzle. This almost always leads to chip recutting, which is very hard on the tools. When doing deep pockets the issue is just multiplied. My choice, full flood which flushes the chips out very well and keeps everything cool and slick. Or completely dry with the optional addition of a dry air blast to blow the chips out. Dry air is much more efficient and blowing the chips away because they don't get sticky with a small amount of coolant residue. Just my opinion, your mileage and others opinion will vary ;)
Thanks
Tim
Thank you for showing the milling and thanks also to your customer for sharing. Really nice to see the sim in the video. How did you get to hide the background of the sim (while only showing the part and the tool)?
Thanks, yes really nice of them to share as well. I set the background color in fusion to white and then set the chroma key to that.
Thanks.!
Did you replace the coolant pump with something bigger? You seem to have about 3x coolant flow compared to my fadal vmc 15.
I have an 1/8 horsepower pump that flows about 10 GPM. I did upgrade the hose to a 3/4" ID which was the biggest I could fit in the tracks. My pump is starting to go, I had it not start a few times this weekend which is really bad with what I'm machining. I just order a 1/4 horsepower 20 GPM pump but I will need to change the wiring a little as the factory circuit wont handle that much load.
Yipee, no electricity.
LOL, this was up for a while ;)
