Centroid Community CNC Support Forum

Quick question. Most of the work I have done so far has been with 6061 aluminum. I am starting a small project with 7075-T651 aluminum. When I look up the speeds and feeds using the CNC Cookbook, they appear to be the same for 6061 as 7075.

Is this accurate? I was planning on using the same 3 flute aluminum specific YG1 end mills.

Thanks... Richard

7075 is harder, so it wants to stick less vs regular t6061.
I.e. you can feed even quicker if you wanted to.

Thanks so much. Really appreciate that.

you can use millalyzer or tools like that to get a more informed decision.

Thanks.
