X4 Rest Roughing problems

[Thee Rickster ™]

i have yet to have a successful rest roughing path to work in X4 like I i have had it work in X3 and X2.

.

.

.

.

 

In the the rest material field I use roughing tool,

dia. .26 corner radius .13. I am cutting with a 1/8 ball.

 

i have done this countless times in X2 and X3 with no issues. Its like it is combining a waterline path with the rest rough path??

 

Am I missing somthing?

 

Any help will be greatly appriciated

Rick,

I've had the same issues. If you pick "All previous opps" maybe it will work better??

Sometimes it does for me

I've found it better to draw some containment boundary's, create another roughing operation inside the boundary and just bite the bullet on the time issue (suck's I know)

.

+1 for all previous operations

[Thee Rickster ™]

murrymold, tried it, it failed.

 

Evil, i am using a containment bnd.

 

I have been biting the bullet and on the cutting air time, but look what happened when ALL I CHANGED was stock to leave to .005"????????

.

.

.

.

Well i guess its cutting less air...

 

Any body having these issues please report them to [email protected] to hopefully get it fixed for X4 MU1

 

thank you

Rick

Do two operations with depth limits active in the areas to cut.

.

If it doesn't work, Hack the S#!t out of it.

[Thee Rickster ™]

That IS the 'semi' workaround.

 

I sent this thread to qc.

semi-

.

a combining form borrowed from Latin, meaning “half,” freely prefixed to English words of any origin, now sometimes with the senses “partially,” “incompletely,” “somewhat”: semiautomatic; semidetached; semimonthly; semisophisticated. Machinists use it as a standard of "good enough"

Origin:

ME < L sēmi-; c. OE sōm-, sām- half, OHG sāmi-, Skt sāmi-, Gk hēmi-; cf. sesqui-

Semi's don't go over 'well' in the adult film industry either.

Are you using the STL from Verify?

 

Something that SOMETIMES works for me...

 

If I rough with .015" stock to leave, RestRough with .02" or greater

[Ocean Lacky™]

Another thing....on the Rest Material page,

 

Pick the 2nd option to IGNORE small cusps

[Thee Rickster ™]

Ocean,

 

i have no use for stl's and have never worked with them from verify or any other application. This is a process issue, it does not work like it should, like in X2 and X3

 

When I choose ignore small cusp and hit ok, the path does not go dirty, when I go back in the parameters the 'ignore small cusps' that I just check 'IS NOT Checked any more". I have never had to use that setting before.

 

It's gotta be broken

Try it..you might be amazed!

As far as I'm concerned, the HST Restrough toolpath is a disaster waiting to happen WITHOUT using .stl's or restroughing without a solid. I reference .stl's on ALL my restroughing paths and the results are very efficient toolpaths without any crashes. Using the "previous tool" method of restroughing DOES NOT guarantee that the stock is actually removed and you may smash a tool in some smaller pocket areas. Using the "previous operation" method takes too long to calculate and the path is rarely efficient. I agree that MCAM's verify is broken, but it is still the only way to create a guaranteed restrough toolpath. I have noticed that saving an .stl fails less if you change your tool tolerance to .002" rather than the default .008" when verifying. If it fails at .002", change the setting back to .008".

[Thee Rickster ™]

How do you use and create stls for tool pathing?

I will try it with the troublsome path immeadiatly.

 

Shouldn't the software/toolpath just work like it did in X2 and X3??

 

How much larger is my file going to be added all this baggafe just to get a toolpath to work properly?

 

Be aware that once I reach a certain file size X4

stops working for me and I am screwed. (An unresolved issue I am working on with cnc software.)

 

Thanks

Rick

It didn't work so well in X2 or X3 either without referencing an .stl in my opinion.

 

1 - Setup your actual stock in the operations manager.

 

2 - Verify your first roughing operation using "stock setup" on the "verify option" page. When it is done verifying, save as an .stl file. Eg. save as "cavity_1000_bullnose_rough.stl"

 

3 - You should restrough your next toolpath referencing the .stl file that you have previously saved.

[Thee Rickster ™]

#1, what do you mean and how? My stock setup is a rectangular block.

 

#2 my first tool is a 3/4 ball and doesn't even

go near the area like the previous 1/4" ball does, will that matter?

Here is the verified 1st roughing path 3/4 ball.

Sorry for not knowing how to use this work around feature. but as you say 3 versions have passed and no fix. I really did have great results in X2 and X3 after the latest mr and mu were released.

[Ocean Lacky™]

verify model looks good...now add the 1/4 ball toolpath and save as STL

[neil qwerty]

Rickster, run all your operations thru verify, while in verify save the results as an stl file. Now when you create your rest roughing operation, select the stl file that you just made in verify as the stock. Mastercam will compare the stl file to the surfaces and machine only the required areas.

 

Neil.

[peon]

Ok, after you verified that 3/4" ball, did you save it as an .stl by clicking on the floppy icon?

[Thee Rickster ™]

Ok,

 

I have geomtry/drive surfs and a containment in that

toolpath(obviously from before trying this method). How do I reference the stl?

 

neva mind I added the cad file.

 

regenning now.

 

Thanks

I agree with peon that using an STL for rest roughing is the most efficient way to go...setting it up the first couple of times is a little confusing at first, but you won't do it any other way after you figure it out.

[Ocean Lacky™]

on Toolpath Type page....on the right side...click the CAD button and browse to the STL. Regen.

on the parameters page under Rest Material, don't forget to change to CAD file before you regen
