Casting And Molding
This week for how to make almost anything I had... Sponsor Week! I spend 100% of my time on my sponsor week demo, and didn't get into the shop until after we finished demoing on Tuesday evening.
I did manage get a pretty good start on a tutorial for casting metal babbitt in the CBA shop. Photographs courtesy of Hye Soo. Thanks!
I reused my dampened oscillation model from Make Something Big week. Instead of ~ 3 feet in diameter this time the mold is just under three inches.
See my rough tool path settings above. Finish cut tool path was the same except with Stepover = 9%.
I milled on the Big Shopbot because it was available. This Worked fine -- However, I think that it doesn't move quite as quickly as the desktop version. When I sent my toolpath to the ShopBot, I got an error message saying [VS parameter set too high. Using the maximum (12)]. My guess - VS stands for Vertical Speed. Accepting the alternate maximum worked just fine.
I'm casting my mold in Oommoo overnight on Tuesday -- I haven't yet been able to cast in the mold, but I hope to catch up over the weekend.
