I need a Path like Raster or Parallel

[Thee Rickster ™]

That cut like scallop.

 

When I use these two it just steps over when

cutting the hills and valleys.

 

When I try parallel steep I get and error

"toolpath calculation error, please contact reseller"

 

Is there a way to scallop a raster or use high speed

scallop to cut like raster?

 

Thanks in advance

Have you used Surface Blend?

[Thad]

Rickstrap,

 

You want to call out a scallop height, not a stepover, right? Click the Max stepover button on the surface finish parallel parameters page and see if that will get you close enough. It may take some tweaking. I'm not sure how close the "approximate scallop height" will get you.

Jay, i cant it it to work without this error.

Plus it didn't let me use a needed containment boundary.

.

 

Dang.

 

I guess I will send it in to In-House.

 

Thanks

[Jayson Kramer]

but in the step wall past 45 deg he does not stay at the scallop height you set.

[Thee Rickster ™]

Thad, I give it a try

 

Thanks

 

BTW its 'MR. Rickstrap' to you

[Thee Rickster ™]

Jays right. It is limited in helping it scallop

or Add cuts.

The flatter area have too many extra cuts.

I am using a .005 step over.

 

I think I should get an acceptable finish the way it is. I will cut it and see how well it works.

 

Just hoping it could be done.

Maybe a Raster enhancement, Add Cuts.

I'll post it in the enhancement forum for feasibility.

 

Thanks

FYI

 

I installed MU3 and the parallel steep and blend paths now work

[Jayson Kramer]

Rick did you try the surface blend this will give you what you want .

[Thee Rickster ™]

I am trying it now. I am not sure if I understand

why it needs 2 chains.

 

I tried picking a sqaure containment bnd, it said

to pick 2 chains so I picked opposite sides of

the square.

.

.

 

It has been processing for 20 minutes( put a .0003

total tolerance and a .005 step over.)

[Thee Rickster ™]

Alright it finished.

 

Its not doing exactly what I 'd hoped, but it

defiantly is a much better path than the other 2.

 

Thanks JAY

Rick,

 

The Surface High Speed Scallop calculates in 3D as opposed to the older legacy path only calculating in 2D. So in many cases, where the older path fell down the new path will work well.

[Chris Rizzo]

Well raster and parallel are constant xy stepovers. You'll of course always get stairs when it's parallel to steeps. Scallop and blend give you a stepover that follows the topography (3d). I think you want blend, which with the proper wire can give you a cut direction like you want, but with a 3d stepover. Also note that blend can do a 2d stepover.

 

If you want some cool sample files of blend and what wire geo does what, I've got a ton of really great examples I use in class.

oh, if I was trapped on a desert island with only one toolpath, it would be blend.

PEACE

[Chris Rizzo]

Let me guess, you'd be trapped with FBM.

[Hardmill]

ROFL, Me mehself and I would be trouble enuff

A raster with added cuts, like a water line with added cuts would be what i'd like if the option was

ther

 

High speed scallop is not the path for this piece

because we don't want to polish opposite scallops

 

So i just used the raster with a .0015 step over

It took and extra 20 minutes but it was polish free.

(It is a graphite slide)

 

I would like to see some of your path examples if

you wouldnt mind.

"anytime you're going to use a parallel toolpath, stop and use blend"

[Storkman]

rick, you can just use a point for the second boundary

[Chris Rizzo]

I just put a folder on the ftp for you Rick (and anyone else).

 

ftp://www.mastercam-cadcam.com/Mastercam_...nd_Examples.zip

[Thee Rickster ™]

Chris those are excellent examples.

 

Thank you very Much

[PrototypeFred]

How can I get access to the FTP link ?

I would like to see those examples.

Thanks

Fred it is at the top of the page here.

Chris, would you happen to have examples on Surface finish project, or pencil that you could put up on the FTP?

 

Correct me if I'm wrong:

 

Blend res set at 1000% produces faster calc times, less accurate toolpaths.

 

Blend res set at 25% = longer calc times, more accurate toolpaths.

 

 

For those that are new to this path (you may already be aware of this), be sure to select all the surfaces next to the blend chains as well or else you may not cut tangent to an adjacent feature and it will gouge.

 

The tool will only cut to the center line of the blend chains so if you need 100% clean up on lets say an exterior wall, you will have to offset your chain geo by at least half the cutter.
