Machinist's Calculator

I thought that I’d be able to find ideal material cutting rates but alas not...

Where’s the metric??! Useless.

Can’t find how to change to metric config

Would like to use this app on my iphone 8 but keeps not loading. I down load the app and when i open it it will not open

But its missing MRR. If it had this id give it a 4 star

Just calculates feeds and speeds, but gives you the option to calculate using different combinations of known information. Not clever enough to cope with variable tool or stock materials. You have to get the feed per tooth for any material and cutting rpms from charts from the company that made the tool. At least that is cutter specific, taking into account geometry and cutter material.

I submitted a request to update or change the layout and they totally made it better. Thanx!
