I am working with my Analytic Geometry students on using the handibot to create Speroids and Ellipsoids. We have made progress. We start with the classic equations on paper, turn these equations into a Microsoft Excel spreadsheet and copy the numbers into an *.sbp file. At first we just went with the CP (cut a Circle from a Point), several calculated concentric circles and with one plunge depth. After burning a bit (hard maple does that), we changed to making several repeat cuts with about 1/16th of an inch plunge for each cut. We broke down the speroid into 14 separate 10 mm disks. We made 7 walnut disks and 7 hard maple disks. We found the handibot did not like using mm settings so we converted everything into inches. Fun math problem. I really like the way it turned out. The students really understood the geometry. They continue to struggle with basic algebra! What fun!https://handibot.com/forum/read.php?2,130,130#msg-130Mon, 09 Mar 2026 16:48:18 -0400 Phorum 5.2.22 https://handibot.com/forum/read.php?2,130,158#msg-158 https://handibot.com/forum/read.php?2,130,158#msg-158
