you are feeding the wrong direction--always feed left to right---the chattering is caused by the bit trying to climb the wall

Don't climb mill on a desktop CNC at low spindle speeds and aggressive feeds. Tune feeds and speeds with conventional milling and your spindle absolutely ripping fast. Then step the feed up as you drop the spindle speeds. You will find a sweet spot where the two meet and you get perfect chips. Then find the relationship between that point and how much you can decrease speed and increase steps while maintaining similar performance.
Then convert to linear speed and your overall tool engagement. Congratulations, you now have your default starting point for all new tooling in that material while doing conventional milling.

"well it didn't like that"
The number of times I've heard or said that on a fresh program.
Lol

Do Americans actually know that there’s cutting value tables ? You can actually calculate what the best speed + RPM is by knowing wich steel, wich cutter (material) and what diameter (cutter) you’re using….. at least that’s what machinists in Germany do 😅

1st step is check your spindle run out. Such endmills need as close to no run out as possible.

It looks like you're feeding it the wrong way. You need to feed in the opposite direction of rotation. From the clip of the first pas you need to go from left to right, not right to left.
Your bit is pulling itself along and that's what's causing your chatter. This is called climb cutting which is only really useful for finishing passes when very little material is being removed. The reason the hole cut has less chatter is due to it being a traditional cut instead of a climb cut.

RPM and feed direction. That should help a ton.

You know that there are tables for this so you don't need to try and error. You can calculate it.

Congratulations, you've learned that Climb Milling is not for hogging out material. It's for a very light cut to produce a smooth, final cut finish.

oh, you weren't trying to knurl the piece?

Don't you have a 5 axis machining center now? Crazy to see how far you've come

Don’t know what you should do as I don’t know shit bout this but it looks dope 😂🙌🏽 keep it

I thought this said a tabletop Civic and I was wondering why anyone would want a paperweight Honda

Yeah climb milling in the wrong direction will make everything worse. Like everyone else has said, feed against the rotation of the bit.

It's climb cutting versus conventional cutting. Conventional cutting feeds right to left or against the cutting edge so the blades are pushing material toward the cut. This style of cut is used on manual cnc machines like Bridgeports. When using any automatic cnc machine you climb cut the material left to right and maintain a constant feed of coolant for a nice finish. I hope this helps in your future videos.

Climb-milling buddy! Keep in mind you want your cutter to pull into your workpiece, not push away from it like that!

I’m old, and don’t know if it’s still done this way, but “back in the day”, my co-worker (from Switzerland) said he had to hand file every type of metal(s) in their machine shop for TWO YEARS before he was allowed to run a machine.
It was the standard apprentice training process of the entire region.
“We have an intimate knowledge of the properties and personalities of every metal, long before we lock it down on a machine.”
He was the best machinist I’ve ever known.

Sounds like its user error.... according to the comments section.

Get a Machinist's Handbook and look up the proper feeds and speeds
