Appropriate to use 'chip thinning' in Facing op with basic end mill?

[vector29]

I have been wondering if there is any benefit to checking the 'chip thinning' box found in the Face op's Passes tab when facing with a plain ole solid end mill. I know it helps when facing with a large diameter, multi-insert shell face mill, but what if I'm using a 1/8" diameter 2-flute end mill for the facing op? If you have not guessed already, I'm using small desktop milling machines on aluminum and brass here (Carbide 3D Nomad 883, OtherMill Pro and Pocket NC v2) with low-powered spindles. 

Chip thinning: Check it, or leave it unchecked?

Chip thinning will generally improve tool life, finish, and speed. You can read more about it here.

Can't speak for your machine specifically but I'd try it both ways and see which gives the best result, chip, speed, sound, and etc.

Thanks for the link Randy. I'll give it a go. Just wanted to make sure I was not heading for some trouble with that option. 🙂

Hi,
Are you planning to implement this option to Pocket milling? It would be very helpful to use this option to pocket mill with milling heads.
