This has been discussed before, use rebuild display list SH-CTRL-R

I've been getting a fatal error everytime I try to save out an .STL from verify. It's never been a problem until X3. MCX3 Overwrite Install Dell Precision M6300 I'm guessing it's because of the overwritten install? Any ideas?

Where in MI?

Send it to the ftp, I'll see if I can help.

Confucius says climb milling produce better surface finish. Lucky Numbers: 1 11 13 77 37

Imported solids will not be associated to their wireframe. The only way this feature works is when the solid was created in MC or imported from solidworks with history. Enlarge your wireframe, then recut the solid with that chain.

Unfortunately it happens w/o shading active as well... It's always something.

Anyone else having a problem with this? After doing a bit of work occasionally I'll lose the ability to highlight geometry... Exiting and resarting mcam remedies the problem but frustrating none-the-less.

Try using pocketing instead?

I thought I'd start a thread about surface modeling. I am in process of porting cylinder heads, and there's been alot of work required before programming can begin, so... Anyone who has used flowline or flow5ax knows the best toolpaths come from single surfaces. Our programmers used to send parasolid or native cad data (solids) out to a design firm to convert them to a single iges surface for porting. I had the concept down (one of a thousand ways, i'm sure), project enough good splines to loft a new surface. The problem is that the projections never fully align, and we need to have accuracy with the created surface. So, here's my remedy... Ideas for alternate methods? 1. Import the solid into MCX2 2. Align with fixture 3. Export solid in position to .X_T or similar 4. Load file in solidworks 5. Create a plane on each end face of the port 6. Create surfaces on each plane to intersect at a vertex and sketch an intersection C/L 7. "Fan" planes between the end planes at 1.0deg or smaller (depending on complexity) 8. Manually go through and create intersection lines of the solid to each plane to create "flow" lines. 9. Clean up geometry, supress original solid and export as .STP (saving 3d curves and sketchs) 10. Import .STP file into mastercam into WCS, further analyze splines, blend, etc. 11. Break all slices (splines) at a common point and create point at break (each). 12. LOFT My results have been very good, not exactly automated by any means, but does the job cleanly. Anybody else have a need to generate data like this, and whats your strategy?

Ok, so the flow 5ax paths worked out just fine. We cut to an offset surface (-.250" for 1/2" tool) and cut that surface comp'd for the tool. Here's the problem.. There is a .110" radius (fillet) around a "bump" feature near the entrance to the port. Cutting in this manor causes an undercut at the fillet and the bump ends up more like a ridge (think humpback whale). My question is this: I want to try out adv. multiaxis tilting thru curve (port path). I guess i'm looking for advice from anyone who's had luck with this. One thing in particular is creating the guide curve. I need this feature to be accurate, atleast the majority of it, we can probably live with an oversized fillet. Thanks

I finally ended up creating curves all across the surface (create>curve>flowline), then projecting and trimming to the next closest flow curve near my original trim line... ...Worked perfectly; no missed cuts or broken paths. Thanks for all the suggestions

Any thoughts to clean up the end of this path?? It's looking pretty good up until the end. I really want a full cut from beginning to end. I've tried adjusting the trimming on the end of the port (ex: projecting it from the start curve @ the same plane) . Any ideas would be appreciated.

Is it happening in lathe? I've had this problem since x2mr1... Constantly trashes my lathe programs.

sorry the groover has an .008"r not .08

Had an issue come up yesterday that I swear I had worked out before... The part is about 4"OD with a U shaped groove around the periphery. The groove has a .06r in both of the corners. Cutting with a .157 groover with an .08r. Problem is when it finishes the groove it tries to cut on the backside of the insert on the way out. Is there an easy way to remedy this and make it cut into the groove from either side on the finish pass? Thanks

MotorCityMinion, eh? Where you working?

I used to have the same problem *ALOT* when reopening recent lathe files... Seems to have gone away in mr2 tho.

Thanks for the tips, I've been tinkering with all kinds of methods. This would be a good time to have 5axis verify!

Just wanted to get an idea on tool vector control. I'm setting up to port a new job and have been toying with a few different ideas on a 5axis flowline. Is there a good way to calculate the tool vector (line method) other than trial and error? EX: A 1/2" dia. 6" oal. lolipop with a tapered shank. Thanks.

Just installed MR2 SP1, seems the tool filter is whacked out. Only a few tool types actually show up when selected. Anyone else experience this?

Ok it's fixed. Turns out there was a bit of malware on the system from an email or who knows what. The app is called WIN32.POISON.K, and it's nasty. Some kind of keylogger or something... Needless to say, no piece of spyware removal software or virus protection managed to nab it all so I reformatted and reinstalled fresh. Good as new... ...Sorry CNC / Mastercam; I am just used to pointing the finger at you. Thanks for all the help,

Wondering if anyone else had this come up yet? Happened three times today already after installing mr2: mcam crashes upon basic toolpath creation (ex: contour). It will hang for a second, then try to read the floppy, finally ending in the send error to mastercam window. I'm not doing anything any differently than with mr1, just curious if it is happening to anyone else. Thanks,

Even with stock properly setup and defined, extended contours, it still goes to zero. Guess i'll live with it... It's bad enough that mastercam crashes every twenty minutes, I dont need to crash my machines too
