Even if you devote 2 hrs to this lecture but understand each and every point clearly, honestly it's a time well utilized. It took me hours to fully understand this stuff and i repeatedly watched segments of this video but now the entire tool geometry concept is crystal clear to me
i have a doubt sir, at 16:21, tool geometry is explained in ASA system....i want to know why the direction of X, Y & Z axes are not chosen in such a way that it satisfies cross product rule X x Y=Z?
