Manual milling machine calculator app

[mirage100]

I have been checking out machining apps online. Does anyone have any info on a good app for my dumb ass. I see CNC apps but no manual apps so far. Just thought I would ask y'all to save time. I don't mine paying for a good and simple app. We ain't to smart down here. Thanks. Mirage

Want simple? All the milling machine and tooling companies made simple slide rule calculators that can be used to determine speeds and feeds for different materials; perhaps look for them on e bay.

Cutting Speeds

This page gives cutting speeds for turning, milling, and drilling of several different materials. It includes a calculator to figure the spindle speed required.

I use the app called machinists calculator. It has a lot of info on there. I like the bolt drill pattern. I have to make a lot of these adaptor hubs for a man that works on big satellite receivers. One side of the spool may have 8 tapped holes of a certain diameter and the other side may have 6 holes of a different diameter. The app works great for setting up where to drill all the holes. I use an Apple iPhone. Not sure if this app works for Android.

If I must use my phone, I use an app called FSwizard. It's a freebie, so there is an Amazon ad tucked out of the way at the bottom of the page that doesn't bother me much. It does all of the DRO functions as well as feeds and speeds with quite a few cutter specs to play with.

I'm a dumb ass also & math isn't one of my strong suits. Rather than accessing formulas, calculators, & online links saved in my computer, I had my brother make me my own app for my phone with the calculators I use most often. Very basic but really useful for me. I won't post any screenshots since it's not available anywhere. Sorry, I guess my post is useless.

I did essentially the same thing and just built a spreadsheet incorporating the various formulae gleaned from the texts. Works kind of like an app if you know what inputs to change and where. After a while I stop using them anyway and just wing it

+1 for FSWizard.

I also have a simple feed rate calc app that’s called…. wait for it… FeedRateCalc. It’s a simple fill in the blank calculator. No look up tables. It does RPM, SFM, IPM and FPT.

And another called BoltHoleCalcLite that does bolt hole circle spacing and coordinates. Handy if you don’t have one of them there new fangled smarter than I am DRO things.

This whole speeds and feeds thingy has been a bunch of nonsensical gibberish to me. Commonly referred to as balderdash. So far I have only used two speeds on my lathe. The slowest speed of 28 rpm for threading and a faster speed of 164 rpm. Don't have to change the belts. Just in and out of the back gear. I need to up my game on this.

I tried reading my 1915 Machinery's Handbook and got more balderdash. Searched online and found some online calculators. Ok how do I translate that to my craftsman lathe. Then decided to see what my copy of the MOLO had to say. Should have went there first. It goes through the formulas which still have my brain spinning like an out of balance top. And then tucked away almost like an after thought are two charts. The Chart No. 1 has SFM along the top and material OD along the side. The body of the chart has a bunch of numbers which turn out to be the different rpm's for my lathe. Of course these rpms' don't jibe with the results from the formulas. The 2nd chart in addition to a lot of other not too useful info lists the SFM for different types of materials. After reading through this section several times ( I can be slow at times) I realize that if I take the SFM from the Chart No. 2 and plug it into the first chart. Cross reference to the work OD and I have the rpm that I should set my lathe to. As long as I can get the SFM for whatever material I am turning I only need to consult Chart No. 1 for the correct rpm for my lathe. Too simple.

Back to Miage100. If you happen to have a craftsman lathe the charts are on pages 49 and 52 of the 1937 MOLO. Print out copies of the two charts and keep them by your lathe. No need to consult some app on your computer or phone. If you have a different lathe you would need to make your own Chart No. 1. I could probably help you with creating this chart if you can post the speeds for your lathe. The manual for your lathe may have a similar chart.

Thanks for starting this thread as it has helped me to hopefully sort out speeds and feeds.
