I need to perform an acceptance test on a machine that has an X,Y table. The manufacturer says that it is repeatable to +/-0.00015". Does anyone have a document that they can share that specifies and acceptance test to validate Repeatability of an X,Y table?
Asked the manufacturer how they...
Is there any application where you would want the center distance between two spur gears to be greater than half of the sum of the two pitch diameters of the gear combination? I have a customer design where on one gear set in the gear train has a center distance of 0.177" and half of the sum of...
If you are creating a 3D model that is going to be used to create a CNC program, how should the model be drawn in regards to the tolernacing. For example, if a diameter is 33mm +0.3/-0.0 how would you draw the diameter? Would you make it 33mm or dimension it at the center of the tolerance?
I have a spur gear that I need to calculate "Span" (Base Tangent Length). I found this website "http://www.meshingwithgears.com/cgi-bin/wwwboard/span.cgi", but I am unsure about "Backlash" in this tool. The gear specifies an Agma Backlash Class A, but when I enter this into the tool it gives...
