Another Taig feed/speed question

[strohkirchw]

I'm doing some test runs in wax currently while tweaking my cad file, as well as putting my tools into my cam program. I was curious what the realistic IPM limit is for the Taig in 6061.

I'm inputting some of my tools into G-wizard and am getting suggested feeds of over 30IPM but I'm not sure if the Taig can even handle them. I would like to get some starting points into the program so I'm not over shooting.

For example, I have some high helix coated carbide 1/8 and 1/4 end mills in regular length and a full slot in G-Wizard is suggesting 1/4 / 6700rpm / 36.5 IPM / .05 DOC. Should I be aimming under 20IPM..under 15IPM?

and see how it goes. Look at the chips you're making. If they are really fine, like dust, you can probably boost your speed a bit. If they're big and the mill seems to be having trouble keeping up, slow down some. Use some lubrication on the cut, keep the cut free of chips and wear your safety goggles...
