@15:40 looks like G01 x. 6 was not in the sequence. Correct me if im wrong. Im starting watching your videos and its very helpfull for beginner like me.
22:17 G02 beginns at X0.5 Z-0.25 and endsat X0.75 Z-0.375 by R0.125. The quation is: are these points projection of the center of the arc /as in Autocad/ or are first end last point of the arc. Tank you.
The points in Question are the endpoints of the .125 Radius. You code to the beginning of the radius using a G01, then G02 to the end of the radius. Ex G01 X.5 Z-.25 F.004 then G02 to X.75 Z-.375 R.125 Hope that helps. You do not have to change feed rate unless you want or need to, Feed rates are modal and only change when you change them.
Neue, I teach this and it is up for my students. I really dont have time to teach you as well...so buy this book and read it www.amazon.com/CNC-Programming-Handbook-Peter-Smid/dp/0831131586
