Newbie wants to create a cutting calculator

i have a question: I want to create a calculator which uses these variables:

feed per tooth: 0.1mm
diameter: 10mm
width of cut: 1mm

then it has to do this calculation:

(feed per tooth * diameter) / (2 * (Square root(diameter * width of cut - width of cut ^ 2)))

is it possible to do that kind of calculations? Could someone maybe show me a example of how it would look like?

yes of course

you can find the math blocks in the Math drawer

A very good way to learn App Inventor is to read the free Inventor’s Manual here in the AI2 free online eBook http://www.appinventor.org/book2 … the links are at the bottom of the Web page. The book ‘teaches’ users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor

You would need 3 horizontal arrangements and a Calculate button.
In each Horizontal Arrangement you would need

  • a Label to identify what to enter
  • a textbox (numbers only) to enter the number.

The numbers would be in TextBoxn.Text
Rename the text boxes in the Designer to identify which number is in them (diameter, etc)

okay thank you

…one thing missing though - the material to be cut. Feed and Width of Cut are different depending on the material.

that is actually not impartant for me because i dont want to create a recommendation calculator but a plain simple calculator (which already exists but i want to do it myself). I was able to calculate everything i want and also implemented a metal removal rate calculator.
