Been using the FSWizard Pro Machinist Calc for a couple months now. It’s basically a CNC milling and turning speed and feed calculator. Pretty solid app if you’re into machining and metalworking.
Here’s what you do: you just pick your work material and tool material, and the app will spit out the recommended cutting speeds and feeds. There’s also a bunch of other handy features like chip thinning calculations and HSM mode. Took me a while to figure some of that out, but it’s pretty useful once you get the hang of it.
Look, if you’re a CNC machinist or work in a machine shop, you’ll probably really like this. It’s not perfect – the UI can be a little clunky sometimes – but overall it does the job. Worth checking out for sure.
