Is here anyone here who understands serial-kinematic nanopositioning?

AI Thread Summary
In serial-kinematic nanopositioning, the resonance frequency of the axis with less mass significantly impacts performance due to its inability to effectively manage the combined load of the upper stage and payload. This limitation on performance refers to the reduced precision and stability in positioning, which can hinder the overall functionality of the system. The lower stage's capacity to support the upper stage and its payload is crucial for optimal operation. Understanding these dynamics is essential for improving nanopositioning systems. The discussion highlights the importance of load management in achieving better performance in such applications.

Hi. I have a question about serial-kinematic nanopositioning.
Why the resonance frequency of axis which has less mass impose a greater limitation on performance? And what is the meaning of limitation on performance concretely?.
 
What exactly is your question about this? I assume you are talking about a stage stack where one rides on the other. The lower stage has to typically carry the upper stage plus the payload, so the overall performance is probably limited by the combined load.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
