  1. Does this process end-up creating either stressed or de-stressed parts? Most customers (especially if a tight tolerance is to be maintained across the entire surface of a wide surface-area part) want to be promised that they are receiving a fully de-stressed part.

  2. In a 6DOF articulated robot arm, of the sort being shown in this video, the manufacturer usually only guarantees a repeatable POSITIONAL precision of about [0.33] millimeters. In other words, these types of robots are fine for tasks such as "pick and place" or "machine feeding", but they are no-where-near positionally accurate enough to perform [0.0001] of-an-inch parts machining.

  3. Are we to understand that the gentlemen presented in this video, for their KUKA robots, are themselves writing the code that constantly determines and maintains the Jacobian matrix used to achieve the final position of their robots' end effectors?

  4. I am guessing that each robot, in its end effector "wrist", has a "hockey puck" -shaped strain gauge, which simultaneously measures force in the x-, y-, and z-axis directions. This version of a sensitive strain gauge is a fairly recent development.
