2D high speed toolpath takes 10+ min to regenerate

[Custom Billet]

OK, I have a quad core AMD Phenom II processor, 6 gigs of DDR3 ram, and a NVIDIA 1GB GeForce 9400 Graphics Card on XP and X5.

 

When I do a fairly simple 2D high speed pocket with small tools, it takes 10-15 minuets from the time I hit the check mark to the time it finishes creating the tool path. I wouldn't think it would take this long? Any ideas?

Not sure about your video card.

Well, I haven't had any graphics issues. It is just when you create the 2D high speed tool paths, or regenerate them.

 

Is there a way to turn on and off using all 4 cores of the processor?

Im firly certain mastercam is only capable of processing with a single core at the moment...not sure if there is plans to change this in the future??? would be nice though!

Any ideas? Call your retailer and tell him to get to the root of this issue ASAP. If the results are not to your satisfaction, let your wallet do the talking from then on.

Click on the arc filter / tolerance tab and try .002 tolerance, a 3:1 ratio and then check create arcs in XY min radius .005 and max radius 100.0

 

See if that helps.

If you want to view the toolpath's motion and see it quickly what you can do is increase your arc filter tolerance as shown in the graphic below. This will generate the toolpath's fairly fast. Once you have the toolpath's generated and have verified that the toolpath motion is what you want then tighten the tolerances back up to the point that you need them at.

 

Just a quick side note I'm working in a metric config that's why those values appear so large.

LOL, tried that. The guy I normally talk to wasn't in, so I talked with another guy that sounds like he has been there a week. I don't know of a comparable software. I have tried some of the less expensive programs, and it doesn't seem to be able to do anywhere near what MC can do.

You da man! Regenerated in 30 sec. This was getting very frustrating.

 

Thank you so much! I owe you a beer!! Or 6!

Can you post the file so we can take a look at it and see if it actually takes that long to re-gen or if something can be done to improve your re-generation time.

I would have no problem with that, but it is proprietary, so I don't want to get myself in trouble. Thank you everybody for your help!

[Chris In-House Solutions]

What about posting the tool, stepover %, depth of cut and other parameters used to created the toolpath. Maybe even rough size of the pocket or area you are trying to cut. Then perhaps someone can try to repeat the steps and see how long it takes to process.

or let us know what your original filter tolerance was set at

Video card wouldn't have any bearing on cpu processing

 

Besides, the video card I have here at work is a GeForce 7300LE

Sort of, each high speed path will use one core independently. Only high speed paths though, and no way to use multiple cores for one path. Provides an advantage when you have multiple high speed paths that need regeneration.

That is what I was told, but when you hit regenerate, and try to do something else, the screen turns white and it locks up until it is done doing it's thing.

 

I checked the settings "Enable Multi-threading" and it is checked, so it should work, but my processor shows 25% usage, which to me would mean 100% of one core.

 

While it appears to be bogged down, I can surf the net or do anything else on the computer without it slowing down at all.

2d HST paths do not use multi-threading.

 

And...if this is a 2d path....one would think you could just share your geometry that only relates to this opetation. A basic wireframe is pretty tough to call proprietary.

I am using a 1/32 flat endmill to do a pocket .030" deep. The outside is a spline and it has block lettering on the inside. I was sent a solid, so I created curves where I needed geometry.

 

One depth cut, 60% step over, 8 IPM and the filter was set to 2:1 and the filter was whatever MC came up with. I think it was around .00037"?

Well, it is their logo, so I really don't want to share it with the world. I can however, draw up something similar and use the same tool paths and upload when I get a chance, just so you guys can see what I am talking about.

If the pocket geometry contains splines instead of only lines and arcs it will really slow down unless the filter is on.

OK, that makes sense. So, is there a way to convert the splines to arcs and lines?

[Chris In-House Solutions]

Edit, Trim Break, Break many pieces, will allow you break your spline into lines OR arcs.

[MotorCityMinion]

Edit, simplify will work on some splines with minimal ill effects.
