I've done all that and it still looks like its on 'thick' lines drawn with crayons.
Its like the developer use thick lines for thin and thats as small as they get.
That's a feature that He Who Shall Not Be Named b!tched long and hard for....Looks like he got his way.

We've had good luck with Schunk in our 18k spindles.

Apparently, it's Live!
click Help/Update Mastercam then when the next window opens click Check Now.
Approx D/L time here: 4 1/2 mins

also, you could extend the parting line surface out over the cavity to prevent the tool from rolling into it.

I put a file on the FTP in the X6 folder CALL Conical Example.MCX-6 to help.
I am using mastercam x4 ...

While I find the HSM toolpaths to have great motion, the thing that drives me crazy with the roughing toolpaths is the stock to leave in Z.
The value I set there is never achieved, always more left, sometimes lots more.
I need to check every depth and make sure that it does not leave like .02" when I asked for .004", then play games with the depth cuts regen hope it worked, back to depth cuts adjust again regen hope it worked. Unless you enable the "Add Cuts", but I dont always want that.
I must be the only one who struggles with that, the "old school" toolpaths at least adjusted the depth cut depth so that the stock to leave was consistant.

A quick and easy work around is a Scallop path set very shallow, say 0 to 10 degrees to knock down any high spots.

Surface Rest Rough would be one way to do it

I've got 4 open right now...no problems

Mpmaster is meant to be generic, so flavouring the post to account for each of these brands is not necessarily the goal. We're trying to provide a platform for users to build off of.
That being said, please let me know what changes you would like to see to the high speed functionality (or any other changes for that matter) and we can assess and implement the changes that make sense given our goal.

On the Cut Parameters page, what are your settings for Keep Tool Down?
I try to remember to set mine to 100% of tool diameter as sometimes Mastercam will randomly set it at 1327% which will yield the same results as you are getting.
-
Opti rough with Step Up enabled may be what you're looking for. 1" DOC with .25" step-up. Trim the air cuts.
-
Create Curves All Edges
Trim curves to reflect desired surface boundaries
Untrim Surfaces
Re-Trim Surfaces to new curves
-
i suppose I could get help from
my reseller if I cant getter figured out
Might be your best bet for success at this point.

So the waterline rest is the better path without stl,
,
only if you don't need multiple stepovers in Z
-
Verify a roughing operation- Do NOT use Turbo mode
Save Verify as STL
HSM Rest Rough
Select Drive Surfs
Select Containment Boundaries
Do not select CAD file at this time
Set toolpath parameters
When you Green Check out of parameters another window will open for you to select STL.
Pick your STL and OK
Toolpath will begin crunching

Glad we could help!

What defines a bad suface and how to find it?
Probably the most common example of a bad surface is one where surface normal suddenly changes direction.
The easiest way to show this would be to draw two lines parallel.
Now, create a ruled surface with the chaining direction of the lines going in opposite directions.
The resulting surface should be twisted.
Use Analyze/ Dynamic to examine the surface and notice how the arrow flips direction near the twist.
Typically, you will find this condition on a corner of a surface. In My experience it's usually an area of .005" or less, so you'll have to zoom in really close to see it
You can use Analyze/Test Surfaces to find them and change their colors to make them easier to see.
Usually you can fix them by untrimming and retrimming the surface.
-
Not sure of the calculations involved, but using the STL seems to be faster...at least for me.
Do you add stock to your tool diameter to account for Stock To Leave?
Example: .750 Ball and .025 Stock to leave would yield a .800 Dia roughing tool in Rest Rough .750+(.025*2)=.800
I find that by doing this you'll be less inclined to be surprised when a small tool goes into a rib or other small area that isn't completely roughed out by the previous tool. (No need to do this when using STL)
-
what are your Verify Tolerances set at?
Mine are set at Tool: .008 and STL: .001
-
Verify all roughing ops. DON'T use the Turbo option in verify. Save verify as STL and pick it as rest material.
-
Rest Rough with STL is best option in most cases from my experiences.
-
or, from one file to another, or from one window to another if you run multiple sessions
Preselect Geometry,
EDIT/COPY or CTRL-C
open the new file or make active the window you wish it import to
EDIT/PASTE or CTRL-V
-
Rick,
Try leaving EXTRA stock on your Rest Rough.
Example: Initial rough leave .010"
Rest Rough leave .011" or more

Happened again this morning.
Need Help - Improving Surface rough parallel tool path
in Industrial Forum
Posted
ok, could be wrong here, But...Doesn't the Surface Rough toolpaths 'assume' full stock? Since the part is already roughed out on an EDM, I would only use Finish paths to complete the job using multiple paths with reduced Stock to Leave as necessary.
