Thanks to BillPSU and dgallup. I receive drawings all the time where the shaft manufacturers will do one of two things:- Add a general PCD, machine the holes to say 3mm below the final intended size and disregard the misalignment. When assembled, line bore to create a true, straight hole...

Hello to anyone that's clicked this link! As indicated above, I have a question concerning the machining of holes on a PCD. To be more specific, holes in a shaft flange (big flange). The PCD of the holes (10 holes) is 900mm. Naturally there is a matching flange with the same number and PCD of...

Can someone help? I'm trying to show a cosmetic thread in a cross section. I've tried the on-line help but thats next to useless. This is what I've tried so far:- In drg properties, changing the 'remove_cosm_from_xsec' to allthe options i.e. none, all, yes, total, no...still no luck. On the...

Apologies for not spotting the question further up..the bush is 6.63" in length... This is where I got to so far.. I calculated a circumferential stress in the bush based on the required expansion of 4 thou over the mean bush diameter From that I looked at calculating an interface pressure...

Guys... apologies for the delay in adding to this thread...I kind of put the file to one side and hoped the problem would go away!!...it hasn't. I looked up Lame's equation which seems applicable for thick walled cylinders. I'd kind of concluded that I was dealing with a thin walled cylinder...

Hi Mike, Yeah, most definitely a textbook problem. Without the textbooks and seemingly no answers to be found anywhere on google, I thought I may benefit from the experience of the guys on here. Hi Greg, Thanks, I have worked out the taper angle to be 1:40 on diameter. I'll have a look under...

Hi Guys...I just registered on here after someone recommended the site to me. I need help with a calculation and as my name suggests, the ol' grey matter just aint doing it for me right now! Okay, I got a taper shaft which is 2.88" dia at the large end and 2.715" at the other. I've also got a...
