To be fair, there are some applications that require very tight tolerances in the application and use and a tool mark could push those tolerances out of wack...however, those have to be VERY tight tolerances and usually seen in very specific applications and industries (Formula One engines is one example).

@@matiastripaldi406 There's always a way, but it'd involve some pretty unusual tooling. Probably a fourth axis, rotating vertically on the carriage, provided the required radius is perfectly circular. Imagine something like a "ball turner" tool for a manual lathe, but used in the opposite way. If it's an oval, or some other more complicated shape, you'd need a fifth axis mechanically linked to the fourth with some fancy variable linkage that would have to be adjusted for the shape. Thank god for CNC, i guess!

One surefire way to bring these people to their senses is to add extra for grinding/honing/lapping the part to remove tool marks. 99% of the time you'll hear - fine, just keep it to the minimum possible. That; 's their way of acknowledging their stupidity. BTW, this part is just a pusher, not some ultra-critical clearance application. A couple of toolmarks will in no way interfere with its function.

Hi, again I am wondering, is the center in de main spindle (slightly) floating and only used as an axial stop? Because it would be over constrained with a fixed center, you could be doing huge damage clamping the jaws unevenly. Great removal rate BTW. At work I was discussing milling vs. turning for hogging out big parts, because the Mazak VTC does not lend itself well to high removal rates, one of our big lathes will do it much quicker. Also it appears the chip thinning milling strategies do not work equally well on different machines.

It's kinda like working between centers. You install the piece between centers, you put an indicator on it and then you tighten the jaws .

I assume your finger nail is calibrated at a hardness lab after every trim. When I worked at a gas turbine overhaul company tool mark (or any surface marks for that matter) removal was extremely important. In aircraft engines the parts are highly stressed so they can be as light as possible and are therefore susceptable to crack formation at stress concentration points. Much time was spent with Cratex sticks smoothing out radii etc. Even grinding surfaces was problematic as certain materials are subject to grinding burns which can lead to crack initiation. These grinding burns are invisible to the naked eye and only show up when etched with nitric acid. The surface will look perfectly smooth but be burned and unacceptable for use. The parts you are making, while likely subjected to huge loads, are very heavily made and probably develop relatively low stresses in the material. While tool mark removal is good practice, it likely would make little difference on this part. Ken

Shuffle blame from design to manufacturing. From manufacturing to maintenance, from maintenance back to design. Welcome to Boeing. Why did it FAIL. The design did not account for reasonable maintenance and manufacturing flaw allowances. "The reasonable test" And what is a reasonable engineer to do, cover those bases in design. DESIGN FAIL, PERIOD, or maybe a rough finish as well. Or lack of maintenance. Needed more grease as well. Probably needed the newer flux capacitors installed as well.
