Hello all, I'm hoping you can help me determine a reasonable strategy to control the amount of allowable twist in a rectangular prismatic shape? If you look at the following picture, I sometimes deal with the types of parts that can have twist induced by various means of manufacturing. This is...

Gents, I have an aluminum weldment that isn't structural per my definition of structural...it doesn't hold anything up or have a way of failing catestrophically, etc. So that said, is there something other than AWS D1.2 I should refer to? I'm struggling to find something while googling...

The attached image represents a generic question relative to dimensioning and measuring a part. Given a "U" shaped part, where the width between the two vertical legs of the "U" is dimensioned, and each leg of the "U" has an angular tolerance where is it appropriate to measure the dimension...

Does anyone use MIL specficiations anymore? Thanks, Mike

Friends, Question about weld bead lengths when explictly called out on a print. On a drawing we have utilizing an 1/8" fillet weld, which joins two pieces of 1/8" Aluminum extrusion we also require the length of the bead to be 1/2". What does AWS or any other standard state about the length...

Friends, In a meeting today one of our manufacturing engineers stated he was going to call another meeting to state "we should never use unilateral tolerancing". As a design engineer, I am against forbidding use of unilateral tolerances as I feel it is removing a communication tool for use on...

Friends, Question for you... The company I work for purchases a lot of flat Al sheet, of about .050" thick or so. We order these sheets from our supplier per a controlled print indicating their size. Having said that I think our prints probably lack some clarity in terms of sheet squareness...

Friends, I'm in the process of developing a quite optimized (in terms of cost and strength) sheet metal tray. The size of the tray and its design in general can be seen in the attachment. The tray will actually undergo some vibration, and from my own testing I've found the vibration to...

Hello all... Question for ya. My company uses a lot of extruded aluminum parts, and we often use the same base aluminum extrusion for different parts. So here is my dilema... I want to have a base part which consists of a sketch that controls the cross sectional shape of the extrusion. Next...
