Switched from eyeballing my feeds to actually writing them down, and my scrap rate dropped off a cliff
I used to set my speeds and feeds by ear and by feel, just going off the sound of the cut and how the chips looked. For a couple years that worked okay on aluminum but I was scrapping maybe 3 or 4 parts out of every 50 on steel, mostly from burning up corner radius tools on finish passes. About 5 months ago a guy at the shop in Wichita handed me a beat up notebook and said write every setup down, tool, rpm, feed, depth, the whole deal. I felt kind of dumb doing it at first but after 6 weeks I had real numbers to compare instead of guessing. Last month I ran the same steel job I used to scrap on and got zero rejects out of 60 parts. My question is do you all log your setups by hand or is there a free app that actually works for this?

Writing it down is the whole trick, no app needed. I've tried a couple free ones and they all want me to tap through six screens just to log one tool change, so I went back to paper. A cheap clipboard and a pen beats any app when your hands are covered in coolant. The chip sound still tells you when something's off, but the notebook tells you what number to go back to.
