Dynamic multi-axis milling

Dynamic multi-axis milling, I saw it on a Chinese website

[Matthew Hajicek - Singularity]

I'm guessing maybe a flow driven with the floor?

[Matthew Hajicek - Singularity]

Hmm. Not exactly, but close.

Ok, I'm betting make a 2D peel, save as geometry, and use for Project Curves.

chuckle... :-) High speed 5-axis milling on a Haas, with a trunnion, and a ER11 tool holder??? Too funny. This must have been for Mastercam demonstration purposes only. If I were to try this I would generate a 2D HST peel mill or similar, then convert to 5-axis with the convert to 5-axis toolpath. Basically that toolpath gives tool axis control functionality to any 2D toolpath.

I would add the step of projecting the peel mill toolpath onto the surface, then convert to 5-axis. I am not familiar with the project option at all, but my guess is that it can be used to convert a 2D toolpath to a 3D toolpath, correct? The 'convert to 5-axis' toolpath would then convert the 3D toolpath to 5-axis where you could specify tool axis control. Seems like a pretty slick way to rough out impellers.

 

Then a couple of swarf wall finishing passes and a blend floor finishing toolpath converted to 5-axis, and a macro to do a radial copy of everything in the control and there you have it.

you have to watch how it projects though because that will totally change your stepover/tool engagement.

 

it's either a 2+3axis and we just can't see that, or 2+3 and project + convert to 5-axis

 

or, or or .. it's a morph toolpath with 'blend spline' as the linking parameters and just happened to work our nicely here

all show and no go

unless it's really soft wax they plan on cutting.

nice toothpick they used for roughing

haha yeah seriously

 

the machine model too is a 'standard' model - can tell from the color. It also could be 5-axis nci imported in..

Make up your mind already! (kidding Tyler)

 

Well, I'll be visiting here more often soon. Was mainly in off topic for the past several years (no questions to ask for X2).

 

Got the go ahead to upgrade.. On to X6! (and newer versions thereafter!) X7 near, huh? Goodie!

 

Bob,

 

Project toolpaths can produce super sweet and beautiful finishes. Definitely worthwhile looking into...You can use a flat 2D containment boundary for projecting on to a surface for machining. Will need two chaining boundaries. I haven't used project much lately, but when I do it gives great results.

yay! we all win

Will need to be careful using this method. There is a lot of Material being left on the blades. Might look to adding more lines down the blades to get little better control of tool axis to get more off the blades if you do not want to leave to much on them. Other than that a good example of a way to accomplish what you were after.

 

Okay dug into your levels and see you have the lines on the flie. You have them normal to the floor and that might be what is giving you some of the tilt issues, but the question then has to come will to much tilt violate the floor when trying to get the walls in the roughing operation. Might have to come with a swarf and depth of cuts to get ti down to what you want for finishing.

 

Did a little more digging and see you are using a ball endmill verse a bull endmill so spending time to get the tilt dialed it would work with the ball endmill with no worry about tilt hitting the floor.

Love this how did you get the 2d geometry for the core rough did you draw it or extract it .. can you just take the curves and project them up to 2d?

[ajmer]

it seems others can do this

Esprit can do it also.

yes i did read this when it came out it seems its nothing really new its just knowin ghow to get it done

[GoetzInd]

I would be interest to see a video of BOB CAD accomplishing this......

[mayday]

Nice path Axel,

now I need to see this getting cut on a machine. How about using some Inconnel 718+. I've yet to find a magic 6mm ball endmill that will take cuts like that

don't take this the wrong way I'm not to beating you up, just living real

Not a impeller but a blisk.

From the link: "Machine tool supplier Mag-IAS produced this video to illustrate an efficient approach to titanium blisk production."

 

Yikes, if that was an "efficient approach", I'd hate to see an inefficient approach.

[mayday]

Joe, why do you say that? what materials do you cut on a daily basis?

[GoetzInd]

Didn't seem too bad to me. Tool life should be pretty good.
