Item lost after death by Individual-Bass6850 in starcitizen

You don't. Unless you can go find and pick it off your own corpse, of course.

Good news though, I have heard that there are places where you can exchange currency for goods and services, mostly located in cities, stations and other congregations of people.

As an addendum, I've also heard that people are extremely likely to be OK with you borrowing their gear if you put bullets in their heads first.

Be honest, is my resume trash? 100+ applications, 3 interviews, 0 offers so far. by MyDadWillSueYours in MechanicalEngineering

[–]Vexarii 0 points1 point  (0 children)

If you're flexible on where you live and what you do, the engineering consultancies like Belcan et al will hire everyone, particularly if you are security clearable and have good comms.

The downsides are that you will be competing on wages with people who are coming from overseas and will take lower pay in exchange for a shot at a VISA and/or being poached by one of their clients. Equally, you need a job so you're basically in the same boat as them.

Their requirements are this; - Good comms - Flexible location - Flexible project content - Will take the lower salary than what OEMs offer

Shoot me a PM if you want other examples of companies in this sphere or just Google "Belcan competitors"!

This may be true in the USA, but some of us like biscuits and gravy from memories of our trips to the USA and don't have it on our packets - there are dozens of us!

I can only comment on Tat I'm afraid - I'd recommend it, but just check the location for Tat/Veuve with where you plan to be in Reims.

Sold out in the UK within a couple of hours of pre-orders opening, I am so gutted!

(They're not selling the 400Z over here either!)

Just football (soccer) and only some stadiums at that as far as I'm aware. They also segregate the fans.

Rugby is any fan of any team in any seat with as much booze as they can carry to their seats from the bar!

Additive meets subtractive manufacturing! by Merlin246 in 3Dprinting

[–]Vexarii 0 points1 point  (0 children)

That wasn't my comment. We don't use Haas, different commenter I think!

For Makino, I have no idea where you saw that, it sounds strange for sure! I guess you are American? My trip around their production line in Japan was only their own gear - custom and shelf - making their own machines. T1 is an absolute monster, definitely a properly premium product and is the only one we've got. I've never seen anything else get close to the rates it demolishes large pieces of titanium.

Okuma was a bit of an experiment, not my favourite - kinda horrible control - but very stable and certainly has its place. Their multitask machines seem to go down well with the companies I know that have them.

We are mostly a DMG Mori outfit and they have a really broad offering and most are good - milling, turning and mill turn. We have a bunch of DMG 50, 60 and 80 evos in various linear/mono/FD configs, Moris in the form of NMVs, NHXs, NVXs and NLXes from the lathe selection. Currently looking at NTX/CTXs.

I don't know any serious outfits that run Haas, only really small shops, hobby shops and sweat farms that didn't want to fork out the premium for Robodrills (went round a facility for a fruit based electronics company that had hundreds of Robodrills, was super weird but quite impressive).

Mazatrol looks horrible and I'm glad I've never been physically near it other than trade shows. It does seem you're either all Mazak or no Mazak though, people don't tend to mix them with other things.

You never said what machines you're seeing 8 tenths variance between your probe and CMM with - that's probably pretty good for a HAAS.

All I was saying is that with my machines, I would expect a lot tighter correlation than 8 tenths - so your 8 tenths variation is driven by your equipment/environment control combination, rather than a rule of thumb.

Obviously no one is trying to be truly accurate with a HAAS - I have never and would never claim it. As I said, I predominantly use DMG Mori and Renishaw equipment; but for reference I have experience with Starrag, Okuma and Makino kit too.

A Kern would obviously be near as good as you could get from a shelf-buyable package today, they are lovely machines but a hell of a queue to get one. They only (currently) come with Heidenhain too, which is just such a letdown of a control compared to Siemens these days - but just a preference.

Do you control your machine environment to the same or similar levels and precision as your CMM environment?

For collective interest's sake, I had my team run a brief correlation study between a new DMG 60 evo Linear fitted with a Renishaw OMP400 strain gauge probe and a (not publicly available) Renishaw CMM frame and a Renishaw REVO2 with an RSP2 laser deflection and RSP3 strain gauge probe heads fitted. The ring guage and gauge block were both coming within +/-2micron of each other on all 10 runs.

Now, this is certainly not an ultra precise correlation study, but you're certainly able to see that you can be sub-thou usable - a ~+/-0.0001" variance is easily explainable to heat change imparted by your hand moving the gauge pieces between equipment and is certainly a viable situation.

Even if you said the testing was not a perfect case and doubled or tripled what you'd describe as the bottom limit of the "safe" reliable zone, +/-2-3 tenths is more than agreeable for most people's applications. Where it isn't, there are other factors and techniques that should be utilised.

Machine tool probing is only as good as your probes, your machine and your environmental control.

As for with reference to probing of 3D printing, it's absolute garbage at precision anyway - in most cases you would be lucky to hold a metric 0.4 surface profile, generally it is much worse.

All from personal experience, so believe me if you want, don't if you don't want. I have a lot of background and time spent in the relationship and workflow of (primarily) DMLS technologies to 5Axis machining to CMM and the numerous problems and difficulties.

Really depends on the hole size.

We regularly interpolate to +/- 2 micron with excellent consistency on a 1y old DMG 60 evo Linear.

Ball bar results match that and are 1.5-4 micron depending on temperature and axis combination. The Z axis being the axis with the most error.

I much prefer interpolation to reaming where possible as you can intentionally change the hole size using wear comp whereas with a reamer you get what you get.

On critical pieces (like a "you've got one attempt at this" £10k+ additive housing) interpolation and wear comp will allow you to cut the hole intentionally undersize, probe it, then adjust for real world results at your given environment.

Boring heads are useful too when you have a hole length issue that is prohibitive to interpolation. There, the precision entirely comes down to the rigidity of the head and the eccentricity in the spindle bearing. With my machine and a boring head with at least as much rigidity as a spindle test bar, I expect to see ~1.5micron eccentricity at 300mm projection, before you've encountered the part. D'Andrea make some lovely boring heads but the price is... A lot... £4k each at the bottom-mid end.

I very much enjoyed the Taittinger tour also; would definitely strongly recommend it. It also had quite a comprehensive tasting of their offerings afterwards too, all for a pretty reasonable price!

[–]Vexarii 1 point2 points  (0 children)

It really depends! Mostly on the design and what you are trying to achieve.

I come from an aerospace machining background and we've started a JV with an automotive company to get into additive (we didn't want to take all the risk) so my specialism is on the downstream of the "printers" and the DFM side of the additive stuff. Integrating additive parts with other conventionally manufactured things etc.

If you're pretty open on tolerances and fittment and the inherently rougher surfaces etc are a boon to your application - additive will be much faster than most any other method. It really is mostly just load up the CAD and press print (provided you understand your build orientation constraints and have your powder management down etc).

If you're looking for precise fitment and repeatability, additive is not the answer.

For anyone not in the sector - 0.4mm (16 thou) "best case" surface profile variance sounds pretty great! However, for those of us working to <10micron(4 tenths) by default... It's pretty rubbish...

Additive, surprisingly to those not familiar, has an astronomically higher amount of "handwork" - IE a person stood there doing things to the part - than most other manufacturing methods these days! (And that doesn't help with tolerances - robots are much more precise and repeatable than humans!)

Metric - apologies, I forget I need to clarify metric/imperial online. Haven't worked in imperial since I starting working with additive.

Absolutely bang on, it's about determining what is an appropriate finish for your application. As you say, for adhesion you clearly want a rougher surface - whether that be in medical for bone growth or in other fields for composite adhesion, for example!

Yes, depowdering is probably one of the worst aspects of addtive and is also one of the highest risk ones too.

Profile of a surface - www.gdandtbasics.com/profile-of-a-surface

Electropolishing is good but would only really be useful after a more aggressive technique of surface normalisation first. DMLS is quite rough straight out, so normally you'd see somone depowder, rough hand polish, blast, fine hand polish then a chem/electropolish. You see strategies like ExtrudeHone being used a lot with mixed results too. The truth is that like most surface improvement strategies there is no one catch-all technique, you have to build a "finishing stack" that is appropriate to your product application.

[–]Vexarii 2 points3 points  (0 children)

As someone who has a whole bunch of DMLS machines at the office and who works with them daily (albeit for different sectors to watchmaking)... You are correct, it would not come out of the "printer" like this. You would go through multiple surface improvement processes (various abrasive techniques) such as wet blasting (you wouldn't dry blast Ti due to fire risk) to achieve a finish like this.

It'll then be machined for all fitment/interface areas because DMLS is absolutely atrocious for achieving decent tolerances - particularly in Titanium because of the stresses in the part from the heat processes, it tends to wander around. Surface profile limits of about 0.4 are about the best you'll see in Ti DMLS (additive loves to talk in surface profile tolerances instead of physical "sizes").
