is there a chance that you old CNC has a worm tool holder. If so there will be radial play in the toolin bit may lead to some problems. But this type of problem, i always seen chatter never pitting.

I agree with force guages reacting to moments and viceversa. Instead of using one force guage. I would use a full bridge setup instead of quarter bridge setup u have. This way u can eliminate moment if u r measuring force or force when measuring moment. Omega do sell half bridge (Two guages...

Lets say I have an Electric Gear Drive Motor. The electric motor is rated at 95% and the gear box is rated for 90% efficiency. I want to know the final efficiency of the Motor coupled with gearbox. I think the final efficiency wud be final efficiency = gear box efficiency * electric motor...

see if this helps. Have a leniar piston which pushes with a constant force and free slide on the back stroke. This way you can push 50lbs. For resisting use a damper (one way damper). you can adjust the damper such that u get 500lbs of resisting force with 1ft/s. but the damper works of...

I have used Flowworks before and it worked well on windows xp. Except for minor glitches. But put computer was a 32bit, and was not quiet mean as yours. So my guess is the 64bit...but I am lost too.

I have a 1/4" seal seated onto a TGP 1/4"shaft. The seal is a double lip with a spring and is pressfit into a housing. we never had any problems with leaking. But this one assembly that has been assembled is leaking. One or two them, may be a bad piece. But all fifteen out of fifteen are...

do any one know how to take into consideration the pressfit issue when calculating L10 life. I have a situation where the pressfit of our bearings is causing negative clearance. i want to take into consideration this into my L10 life calculation. I am thinkin of pressfit causing a radial force...

is there anyway i can take into consideration manufacturing defects into calculating L10 life of a bearing. do any one know if there is any tabulated values of frictional losses in gear mesh. i hope i am not sounding stupid when i am asking this.

I am posed with a problem which i have no clue about. I am testing a gear transfer. The gears are all Spur at pressure angle of 20°. The gear oscilates back and forth in its axial direction, now if it was radial, that would have made sense to me. The gear is enclosed in a housing. It is...

take the derivative of the equation with repect to "x" and then plug in "x=2" with resultant equation. that should be your slope of the line.

There is a pressure drop as your altitude increases. If there is a pressure drop there is a drop in temperature, have u ever noticed a compressor in a garage, the nozzle gets cold as u let the air out. Same principle applies here. And there is also radiation loss to the outer space. A...

i would use cast iron if u want good vibration dampning, a ply wood encolsur shud work well...u can get fancy and even put a lexan window. as for as actuating, cam shud be more consistant and cheaper.

i am not a kid, but that thins is COOL!

well its not any equipment. its a thermoset plastic polyurethane, and they defined the maximum service temperature, air to be 270°F.

if you are concerned about the bolt coming loose cause of vibrations and irregular loads. i would consider a fine thread which do well in vibrating conditions. But there is a disadvantage to this as they do not high loads. Pre-loading the bolt shoud work well.

dont know much about this topic. but where the bolts were pre-loaded. slots are put for thermal expansion, but if your vessel is circular where the two vessels are comming together, i wonder y u need slots, as metal expands along its circumfrence, so theroetically the bolt circle shoud move...

I am trying to make sense out of this. When a manufacturer says Maximum Service Temperature, Air is 270°F what does it exactly intending.
