Steve P I was thinking of coarse, 8 pitch, or acme threads. But it makes sence, you would have to adjust the blank dia. to compensate for the material removed in the thread cutting. Thanks
@@Smigger97 Well obviously. lol That's why I included the lol at the end. Although I HAVE damaged a die with material it was supposed to stamp a part from. lol
CNC machines were invented, developed to eliminate the need for skilled machinists. They would rather pay outrageous money for a machine than pay a skilled human. One reason we can't build a Saturn 5 now. We have the plans, we lack skilled humans.
saturn 5s have been replicated with a modern design. That video on youtube is very misleading and human error is by far the biggest problem in a shop even for a journeyman machinist. humans just can't compete with a machine that never messes up, gets sick, or leaves for some reason. also machines can have a 24 hour day. most people leave after 8-10 hours
The Saturn 5 has NOT been replicated with the same thrust, even NASA admits that. The Saturn 5 was hand built and carefully adjusted for best performance by skilled technicians. The reason you have human error is because CNC shops don't hire skilled machinists, only operators and programers. I have been in several shops since 1970 from coast to coast and I have seen it all. Back then machinists did not miss days, they worked tons of OT. CNC machines are only good for production runs and only because skilled toolmakers have been phased out because companies do not want to pay a liveable wage. The cutting tools have been dumbed down so even unskilled operators can change them. I shake my head when I see these obese operators sitting in a chair watching their machines they babysit run. It is no different than what Ford did with the assembly line, kill off skilled workers in lieu of human robots. These machines do not run 24 / 7, they require lots of maintenance and break down often The tooling costs are outrageous and they will make a barrel full of scrap before they make one good part upon set-up and crash tooling at an alarming rate. Employees still get sick and leave more often than before. There is a second shift in years past, if that was needed when skilled humans were employed. I'm sure you make your comment because you don't know any better. If you doubt my comment, compare machinist wages to that of other skilled trades.
The Saturn 5 was NOT built by hand, it was built using the CNC machines of the time. CNC is NOT something new, have been around for more than 3/4 century, but have been significantly improved in the last two decades.
You are mistaken on both counts. Saturn 5 was hand fitted just like I said. Also you are referring to the silly old "Tape" machines, which are obviously now a relic. Nice that you couldn't contradict any other part of my comment. Didn't mean to insult the "Operator" in the comment section. BTW a nurse makes about $75 / hr. How much do you make as an operator? Ha, $12 to $15? Get the point?
Mike M -- Now you're trolling, but, again, automated machines that do not require constant human intervention have been around a long time and NASA and its contractors were using cutting edge fabrication techniques since the beginning of NASA and well before that. Your off-hand comment about "hand fitting" isn't any different today though the need for it is far less given the higher tolerance of modern CNC machines. In fact, one of the main reasons the aerospace industry, among others, use a lot of CNC machines is that they are better at making parts to a higher tolerance. Yes, multi-pallet CNC machines with robotic loaders require fewer low skill workers but tend to require a greater number of higher skill workers with skill in CAD/CAM and G-code. Not sure what your comment about nurses and operators is about as I'm neither.
