Rob Wagel

Perfect I use the trig and sine bar functions everyday. Only problem is my phone gets filthy from using it so much.

Aaron rodriguez

Work's good The only problem is just application icon just shows an Andriod icon with Words Machinist calculator under it.

Clinton Schmidt

C. Schmidt I have a no-contract android phone and noticed that when I use this app it disabled my phones power off capability. Had to remove the battery and power the phone back up otherwise it's a great app. Would like to see a grid pattern calculator with it though.

Lalo Arroyo

A Great app, if it's possible, help on how to make a circle program, I can never get it right with the x, y, i & j

JAMES MANNES

Great technical app Anyone in the machining industry should have this app. It has everything needed to answer regular everyday questions on the shop floor. I use it in the QA department and am constantly sharing with my coworkers on the floor.

Trades Math Calculator September 3, 2014

Hi Aaron, thanks for letting me know. I've had a few people mention issues with the S5 compatibility and am looking into what is the problem, and hopefully be able to get it fixed in a future update. Trades Math Calculator August 5, 2013

It was definitely time for an update, I hope you like the new layout! Please e-mail me with any suggestions/criticisms, feedback from users will help me make this app perfect. Requests below On the speed and feed page, it would be helpful to have a # of flutes box.

Usefull Would have been 5 stars if it had a compound sine plate function

Colby Awesome app! The ability to toggle between metric and inches, A+++!! Only thing missing for me is feed per tooth calculations. Hope to see that soon!

Good Good app, be even better if it could work out ball sizes!

Perfect, maybe a SFM calculator when you enter workpiece material and tool grade in an update? Maybe even throw a drill/tap chart in there?

The small red letters are very difficult to read in the right triangle solver. Would be nice to see more features in a $4 app

Wrong Answers It's always off on angles. Can't figure out how to make it match what the calculator and my trig book says to be true.

Trades Math Calculator December 14, 2013

I'm sorry you're having problems. We have MC running on multiple platforms and have not run into this issue before. Can you post here or email us some specific examples of where you're getting a wrong answer, and I will look into it immediately. Review deleted

# What's New

3 Wire Thread Measure Function Added

Quickly make all the calculations required to measure screw threads using the 3 wire method!

Whitworth (BSW), UN, ISO Metric, Trapezoidal, Acme, and Stub Acme. Uses formulas that give very accurate results for lead (helix) angles generated by single start threads. When measuring threads with larger angles, such as UN or ISO Metric, results will be highly accurate for threads with lead angles up to ten degrees.

## Trig Calc

jvanpelt

1

This very basic app allows you to calculate right-angle Trigonometry values with a simple, easy to understand interface. The app takes two arguments as input (you decide which two) and then calculates the remaining values for you. The app is very simple and someone who knows trig by heart could accomplish the same thing with a basic calculator, but it may be useful for those people that don't use trig often. Known Issues: some unacceptable types are not blocked (big angles will result in negative side lengths)

## Drilling & Tapping Calculator

The Drilling and Tapping Calculator from Sandvik Coromant is designed to support engineers, programmers and machinists when working with drilling, tapping and reaming tools. This includes machining calculations, cost calculations, hole size for tapping, drill selection for reaming and ISO bore/shaft tolerances.

## Measure Threads with 3 wires

Sometimes it is not possible to use a thread measuring micrometer to measure screw threads, so the measure over three wire method must be used.

Use this application to quickly and easily do all the calculations required to measure ISO metric and UN 60 degree threads, Acme and Stub Acme threads, and Trapezoid threads with wires. The only thing it can't do is help you to hold the three wires in place AND use the micrometer at the same time!

You start with the nominal thread size, thread pitch (or TPI) and wire size.

You cancalculate pitch diameter or measurement over wires or both.

The thread measurement over wires calculator will also give you the best wire size.
