Hey folks, per @vince.fab’s recommendation, I dug into chip thinning when I started milling aluminum to make sure every flute cut an appropriate amount of material and didn’t rub instead of cutting. However, there is only one online calculator I could find that would do the math for you (Iscar one) and it requires you to enter a lot of information before it will give you anything since it wants to calculate a lot of extra values (MRR, angle of cut, etc.) that I don’t care about. I found the math for chip thinning simple, so I wrote a spreadsheet that would calculate recommended CPT/chipload using only the necessary parameters.
Enjoy this and let me know if you have any feedback.
