Sorry for not seeing "LaszloK" first post about MU2

Looks like I need some vacation:-)

Is everybody on vacation since nobody has noticed this:

Just finished a little roughing test

310cm³/min MRR

You could also use dynamic contour. Would work very well for this job.

Very familiar with that wheel and how it actually performs, thank you for sharing.

 

I didn't realize the splitters had the wave, the one I saw only had it on the tall blades.

 

Are they using BE or another solution?

Where do you know it from? Is it better than normal billet impellers?

They're using hyperMILL and their multiblade package.

Is that the "Bat mo wheel"? What industry is he machining them for?

Yes it's.

It's for drag racing.

Yes, I took it from there... and thanks for sharing NREC, I didn't know about them before... really cool to learn about a new solution...

 

The part on the video I saw it at EMO last year at Siemens booth... very cool too...

NREC is specialized within multiblade stuff. Their cam solution MAX-PAC can only machine impellers, blisks and shrouded version of these 2. But it should be really powerful.

A friend of mine is machining these impellers.

Mic, what brand machine is that in the Youtube video? (With the washing machine door).

It's an Alzmetall GS 650/5-FDT with Siemens 840D controller

http://www.alzmetall.de/alzmetall/index.php?id=gs650-5-t0

They make some really nice machines. Much more rigid than Hermle and other Gantry+trunion style 5X.

By the way, this is one of the coolest impellers I've ever seen:

 

Taken directly from NREC's website But yes it looks nice.

Francis turbines might sometimes be more complex to machine than impellers

When you're looking at dedicated impeller/blisk software the price gets.. astronomical. We have customers that have spent many times the amount of a full multiaxis mastercam seat just for impeller/blade machining software. Granted it does a great job, but you pay for it.

 

yes I know many people get by with mastercam and other 'off the shelf' cam products that might do a great job, but the total cycle time has to be taken into account, or how much up-front development was put into the software. We have some customers who have done some amazing things with 'simple' cam, but they also have had a full-time software engineer develop the plugins over the course of 6 months..

Sounds like NREC. I once heard a pricetag around 100k USD for the full MAX-PAC bundle. For that much you can almost get a Level 3 Multiaxis and a VF-2TR to run the job on

Ok -> I challenge them to cut with BE using a bull mill. Crossing my fingers here

 

The system they used as the benchmark is able to do a lot of nice stuff with bull mills... :cough: Hyper :cough: German :cough: too :cough:

 

Just saying...

In hyper.... only Flank Milling ( SWARF ) and Plung Roughing by default supports bullnose tools. But if you know the hidden - and powerful - cfg-parameters you can open up for bullnose on all the multiblade cycles

thanks for the quick reply, the hand dial will move the axis, but I have a program that will work on one A61 that has a job on it, but for some reason this one keeps alarming out when it tries to run G93 ? We never have tried to do any 4 axis similatnious work on this machine, and can't remember if we purchased the option. We will call the dealer tomorrow, to know for sure, but was just looking for a quick answer, from all you guru's.

G93 Inverse time feedrate is a controller option.

I don't see any G19 in your main program nor sub

You're right... it'll get killed by a Matsuura with an 840DI

 

+gooogolplexian

MX-520 with real 840Di ( no Yasnac front end ) would be awesome

DMU 50 wont be beat!

Perhaps not on price, but then on almost everything else

The back of the spindle is the Z axis cover and the protrusion on the trunnion is the C axis motor covers. Any 5 axis machine has collision points. The key is to have good verification software (3DVM, Vericut, Camplete) and realtime collision avoidance features in the machine. The attached picture is from Okuma 3DVM software. It is showing a possible collision point on an MU400. However, with the CAS option enabled both the 3DVM software and the machine would stop before the collision happened. CAS even works in MDI, JOG and Handle. You can put the machine in JOG, close your eyes and push an axis feed and it would stop before it runs the machine into a collision with itself like in the picture.

Looks like you need very long holder to machine small part at A-90. Otherwise you'll need a high fixture and then you'll end up not having enough Y-axis travel.

The MX-520 comes with both IPS and Camplete. Then you've both offline and online collsion check.

Fissed for accuracy.

Our stock MX-520 will come with "High speed high precision + 5-Axis related option" package

If you're looking at a 5-axis machine I really like the Matsuura MX-520.

http://www.matsuura.co.jp/english/contents/products/mx520.html

 

It has great access to the machine table, which is ideal for one offs in my opinion.

I don't think it comes with all the bells and whistles for 5-axis simultaneous machining but for multi-side parts it would be an excellent choice.

And it's a Matsuura which are one of the best made machines going IMO.

Get it with the "5X related option package" and you're good to go. If you are US based and buying through Methods you'll get it bundled with Camplete:-)

stl is triangle data. I don't think you can convert this into stp ( solid ) data without using somekind of reverse enginering program like Geomagic Studio or similar.

Thank you for the replys

Did also try Blade Expert but skiped it because it wouldn't allow bullnose. Ballnose roughing takes way too long time.

With the trim/extend function I managed to machine the entire pocket, now I only need to get the tool inclination right so it don't gouge the left blade.

Heidenhain control?

Sounds like a problem with the position monitoring. I think there is a timer parameter or something similar that can be increased slightly to overcome the problem.

Hi

I've to machine this fan on a 4X HMC.

I can't get the roughing to machine the entire area between the blades.

What am I doing wrong?

FAN.zip

Thanks for the reply.

After a call to the local grinder we ended on 14,0g/cm^3

I know we can get material with higher density but standard carbide has a fair good price. As we can use Ø20,00 they just need to cut it in the right length.

I would expect pure tungsten to be expensive?

No need to weld as it's designed as a press fit.
