Thanks. I have the frame done using some of the above methods. What is the proper way of presenting them in 2D orthographic and isometric views for engineering drafts for say documentation and manufacturing etc? For precision components this is easy and I'm used to it. When it comes to frames...

I'm used to drafting precision mechanical components with well defined tolerances, feature positions and use of locating pins for assembly etc. Basically CNC machined components that fit together nicely and where each individual part can be separated out nicely and can be drafted easily. But...

I have the data for the non-FRF FFT. The FRF is just the processed raw FFT data where amplitude is Aresponse/Aexcitation both of which are measured. But the noise issue is still there though, if the system being measured is inherently noisy or very low in quality factor. Perhaps the displacement...

For braiding machines of ropes or braiding over preforms, how is the initial yarn loaded and held before the braiding process takes place? Is there a yarn puller that you hook each individual yarn from each bobbin to the holder? Is this normally done manually or is there an automated way to load...

When programming 5 axis CAM, say using conventional 5 axis machines (X Y Z A B) with a trunion table. If A, B and spindle Z axis are not intersecting, is there normally correction for this in the g-code? Do most CAM assume the axis are intersecting?

Yes, but sometimes you cannot eliminate noise or the system is inherently noisy or low Q-factor, like the water-immersed rudder example I was mentioning. Surely there has to be a method? Ok, but lets forget about the issue of a noisy system. What are the methods used for curve fitting in...

Correcting my typo: I meant to say in the OP that the signal to noise ratio is too low in the first paragraph. I dont have any data with me at the moment on hand, but just imagine the worst kind. Very noisy. Highly damped. Very low Q-factor. Very broad frequency bandwidth at -3db. The kind you...

Say you get FFT of some response (be it vibration or noise spectra). If the Q-factor is low and the system is noisy, its possible you can have some frequencies having higher or equal amplitude than at other frequencies which are not the actual resonance peak. In other words, the signal to noise...

What about carpentry? What carpenters do often involves design/engineering work too. Do carpenters routinely have structural engineers sign off on their designs before its a go-ahead for sales? *I know they dont do this. What about artists? Artists can sell statues etc that are the product of...

Trying to understand the professional engineering field a little better. There are many fields of engineering. There are many countries with different regional and federal level rules. There are international issues also. In general, for developed and western countries, is a professional...

Automation based companies are far and many. This ranges from CNC machinery, to articulated industrial robots, to custom automation systems. Sometimes you see these companies offer some kind of full machine simulation that are either merely as a visual demonstration in a presentation or if...

Is the CAD portion of CATIA similar to how SolidWOrks operate in terms of user interface, flow, structure and how parts are modelled etc?

Ive never tried NX before. In terms of user interface, controls, flow, how parts are modelled etc is the CAD arm of NX essentially solid edge? Or is it different?
