LESSON 6.1 · 2:17 · CHAPTER 6 · THE MACHINE AND THE CELL
Count the axes
Each axis added to a winder makes a new family of shapes windable: spindle and carriage wind pipes; a cross feed and eye rotation make closed vessels practical; a six-axis robot opens shapes with no straight axis.
Predict · at 0:44 in the video
What's the minimum number of axes to wind a closed vessel, with a turnaround at the pole?
Two, in principle. Spindle and carriage can trace any geodesic on the vessel. But the eye stays out at the cylinder radius, far from the pole, and the free fibre swings about.

About the numbers
Simulations in this lesson are our own. Where a number rests on an assumption, the video marks it with an asterisk and says where it comes from.
