Feeds & Speeds Customer Insights

1. Could update with different cutter profiles, assume this is for flat end millsThis is the best app I could find for calculating feeds without knowing the material properties.

2. Now every time I put a value in it just gives a popup saying it's just a reference blablabla I hit the agree button and it just repeats the exact same thing over and over can't get past that stepBest one on the play store.

3. Just plug in the size, type, teeth of your cutter and select the material, works like magic.

4. Does not help you calculate anything...just does some simple math based on all of the parameters you input.

5. Whatever your 'max' spindle speed is, this app calculates chip load/tooth etc.no matter what I put in for the machines max speeds it tells me that is what I should run it at.

6. If you want to use it for turning just put in the cutter has 1 tooth.Looks good.

7. I should not be running at 3000rpm on a 1/2" mill through stainlessVery good and useful app for vmc.Love this app.

8. Simple.Great little app...Very nice aapIt worked before then just stopped.

9. You can add your own materials, I added materials under the older codes like en1a, as that's what I am used to.

10. Simple and accurate so far.

11. I would make some tweaks to the interface to make it perfect.
