A lot of information in easy to use app

I have been using this app for about a year. I use it relating to training I do with machinists and machine operators. It is one of the simplest for people to understand while having enough information to do quality comparisons of cutting conditions.
MRR - metal removal rates calculation (helps qualify if a new machining approach will actually save you time before experimenting)
HP - horsepower calculations, allows you to know roughly what power you need to pull a certain tool. Very handy when working with light duty low HP machines. (this part does require using a Chart Sandvik has on their site for material hardness (specific cutting force “kc”)
Chip Thickness - quickly calculates adjusted chip load for milling cutters weather having an angled insert (face mill) or taking a light side cut.

All needed data is easily input in this app.

I sell Sandvik

This is a great tool to use at the machine when making process improvements. The calculator factors in radial (and axial in the case of round insert facemills) chip thinning which is great for those that don't have a strong math background.

Bring back the previous version

I've been using this for 3 years. It's been very helpful for me.
The previous version is faster and much easier to use compare to this newer version.
The selection box is too small and make it very hard for the user.
Since my work required me to deal with metric system. It will not change permanently though you have change into metric. I personally think that Sandvik should really consider to improve this.
