Challenges with chatter in square shoulder milling

Added: 2026-05-17

[00:00:00]But obviously chatter is the the issue here on surface, of course. So, what do you have any good tips?

[00:00:05]>> Yes, and then it's not necessarily that you need to reduce your feeds and speeds and and chatter a lot. Today I am in Lotem, where they produce solid end mills in Seco. And I also question on Instagram, what is most common issues when solid milling?

[00:00:21]And the most common issue is not a lot of chatter. So, we will discuss some of the issues here today with Seco and some.

[00:00:30]So, uh here we are with Ron, he's the product manager for solid end mills.

[00:00:34]Mhm. And we will be discussing some of the issues we have.

[00:00:38]Um chatter was one of the most uh it was the most uh common issues that people have with with uh solid milling. Yeah. Can you tell me something about that? Yeah, sure. Um yeah, chatter indeed is a quite common uh issue, and it happens a lot when you have very high metal removal rates, or if you have very long protrusion lengths uh where the tool is tool is sticking out of your tool overall a lot. Um so, yeah, then uh indeed chatter can occur very a lot. Or also if you have a uh not so rigid uh tool setup, where either the tool holder or the clamping device uh is not as rigid as you want. Yeah.

[00:01:15]Then chatter can occur. I know some people uh think it's a bit too slow sometimes, they want to remove more.

[00:01:22]But obviously chatter is the the issue here on surface, of course. So, what do you have any good tips?

[00:01:28]>> Yes, and then it's not necessarily that you need to reduce your feeds and speeds and and chatter a lot. Chatter is quite a lot about harmonics as well. So, if a tool comes in an into its own harmonics, then it can start vibrating. Uh and you can test it very well with the harmonics by testing the harmonics uh sweet spot.

[00:01:45]Uh and that you can do by tapping with a vibration tool on your tool, and then you can see a nice uh curve uh how your vibration looks like on your tool. And then from there on, depend uh depending you can select your your tool uh feed and speeds. And other uh topics to to include is also if you uh in uh add certain features on your end mills like for instance an unequal pitch or an equal helix angle so to make the geometry unequal as possible uh because that also reduces the uh the vibrations or the the chatter.

[00:02:18]And you always need to look of course to your tool setup. So make sure that the tool uh is mounted properly in your workpiece as you have as short as possible protrusion length and also your workpiece is uh set up well in in your machine. Yeah, I guess runout is also an issue against >> Yeah.

[00:02:38]Yeah.
