User reviews

Great app and very useful

Every thing is available that you should need for reference needs as a machinist to a point only thing it doesn’t have that I have to go elsewhere for is metric thread information.

Best machinist app out there!

I’ve been using this app since the creation of it. I use it everyday and show it to all my customers. I’ve been selling carbide since 1988 and have covered the Bay Area and Central Valley in California for Mitsubishi Carbide cutting tools for the past 17-1/2 years. It’s very simple and user friendly. Years ago I used an app on my old palm pilot called β€œMachinist”. I wish these 2 would get together and create one together. β€œMachinist” was amazing and had a materials data base and would allow you to input the machine data such as rapids, horse power, etc.. so when calculating drilling cycle times it would allow input for distance between the holes. Keep up the great work and thanks for the app!!

Useful

I really like the app and use it often.

It would be really nice if you could add cycle times to the drilling section.

All sections

Issue!

Using new IOS 10. When right triangle solver is used to calculate. It will take the first known with a decimal point. However when you put the second number in with a decimal it closes the app???

Needs update

Needs update crashes when adding decimal places to more than one place otherwise it works great

FAQ

What kind of calculations does the Machinist Journeyman app offer?

The app offers a wide range of calculations for machinists, including milling feeds and speeds, chip thinning, turning calculations, tap drill sizes for various thread types, trigonometric functions, sine bar calculations, metric and inch conversions, and estimating job costs. It also includes specialized calculators for bolt circles and threading.

Is there a metric version of this app available?

Yes, a metric version of the app is available. You can find it by searching for "Machinist METRIC Journeyman" in the App Store. This ensures users can perform calculations using metric units as needed.

What are the main sections of the Machinist Journeyman app?

The app is organized into several key sections: Milling (IPM Feeds, IPR Feeds, Misc.), Turning, Drilling, Math, Conversions, Estimating Calculations, Salesman Calculations, and References. Each section contains specific tools and calculators relevant to that area of machining.

What makes this app useful for everyday machine shop tasks?

The app is designed for user-friendliness and provides dozens of everyday machine shop calculations. Features like chip thinning calculations, circular interpolation adjustments, and quick access to tap drill sizes and conversions help streamline workflows and improve accuracy in daily tasks.

Does the app support custom thread specifications?

Yes, the app allows you to calculate special thread specifications rather than being limited to a pre-determined list. This flexibility is crucial for machinists working with non-standard or custom thread requirements.
