I decided to make a screen recording that will explain kerf and kerf-compensation. It’s about 15 minutes long, and I use the phrase “drive it home” far too many times, but I think it will clear up any lingering confusion.
And here’s the file I used. It’s a SolidWorks 2016 file, so many programs probably aren’t going to be able to open it.
