Chipthinning Calculations?

Hi There:
I am trying to make sure that numbers calculated on my newly download software is correct.
So far so good. Here is a chipthinng example given by Ingersol cutting tools. I plug the number in on
F&S Wizard and the numbers don’t match. Below is there website
http://cuttingtoolschicago.com/metalcuttingtools/tag/radial-chip-thinning/

Here is what I did. I check mark ball endmill and inputted the following:

2 inch ball
1 flute
RPM 1973
Vc 500
Feed 19.73
Fz .010
Axial depth .125
Radial depth .125

I check chipthinning and FS Wizard gives me: Feed 84.18 Fz .0427
I get this with Ingersol: Feed 61.3 Fz .031

Which one is correct and do FS Wizard use the same formula?

Hello Omar,

I just checked my code.
You are right.
I fail to account for effective diameter when calculating radial chip thickness when calculating for ballnose endmills.

I will fix it in the very next update.

Good find!

Just an update.

I have fixed this problem and the new version has since been available on both Google and Apple stores.
