Aaron your always a huge help! Hope everything's going well with your shop and consultant services! your a great asset to the mastercam community and I hope you know how much many of us respect your knowledge of the software and machining in general!

heres a great video that the haas team made on the G187 topic, it explains how and when to use those codes in a very detailed mannor https://www.haascnc.com/video/tipoftheday/lwujoXvgGzA.html also i assume that your machine would have high speed look ahead enabled but if not i would suggest getting that added to the machine if your gonna run a lot of dynamic.

found more info, knowledge base article 17521 https://my.mastercam.com/knowledgebase/optimizing-simulator-for-small-parts/ talks about this topic, it does state 4 is max for Precision Factor. if its been working for you though no problem just telling you what I have read about before and its outlined in this article

ill have to look where I read about it when i get back to work tomorrow. perhaps with the complexity of your toolpaths and parts you have not noticed a problem, with some of the parts some people work with cranking that to the max can cause an issue with performance. edit, im not saying that you do not do complex work, i have been very impressed with your c-hook and other work, so hope that doesnt come off that way. i just mean everyone does different work and some of the work i have seen already is straining verify at default settings for some people. also some people do not get the fastest systems to work with even after begging management for an upgrade

the way i always think about the slidy bar is, sliding it to the left means your loosening up the cut tolerance, giving less of a tolerance to the arc filtering, making the toolpath calculate faster because the toolpaths initial calculation can deviate from the real shape more. But with sliding it to the left your getting less arc filtering so less arcs will be fitted in and youll end up with more code where when you slide it to the right, your effectively tightening up the cut tolerance so your initial toolpath calculation takes longer but will calculate more closely to the real part shape, but since the arc filter side has more room to move things around and fit in arcs it gives less code in both cases the toolpath will still meet the total tolerance condition set on that arc filter page at the top. So your going to meet your total tolerance either way, and in a perfect world if we had no tool wear or tool deflection etc. the part would come out within that total tolerance, So i never slide mine to the left because i would personally rather have less code, i either leave it on 50/50. or ill take the slidy thing to the right so i get a longer calculating toolpath but fits more arcs and lines into the path. I think thats the easiest way to look at it for me and makes the most sense.

if that actually works then you have found a loophole or exploit. Because many customers have paid to purchase the Unigraphics translator to open up UG files and that is the only way it can be done as far as i know. so if that's true that you have been able to do that then maybe they patched that

just be careful if someone does this, cuz going too much on that can lead to issues. What i do is copy and paste the Simulator defaults file in this location, C:\Users\name\Documents\My Mastercam 2023\Mastercam, i then rename one of them "High Precision" and make those changes only to the high precision one, then anytime i want to use the high precsion one i just go into verify and go to file --> defaults --> change defaults and pick the high precision one. That way i dont mess up my default verify settings and only get the change when i really need it. i thought we only need to change precision index and to not go above 4 on that, but i could be wrong there...

you did purchase the Unigraphics translator correct? https://www.mastercam.com/support/technical-support/translators/

my system has an Intel(R) Core(TM) i9-9880H CPU @ 2.30GHz , so its not a bad cpu but the regular mill and Mill turn simulations i run can sometimes get pretty involved.

thanks mike and good to know, i honestly always thought it was my gfx card getting bogged down with mach sims but must be something else, so i might be wrong on that but i definitely see the biggest performance issues with machine simulations on my pc's, not many mastercam related tasks boggs my systems down except that.

its related to stock size most likely, mastercam automatically reduces graphics quality on larger stock sizes, shrink your stock to only fit around one of the features and re-verify and you likely will see what i mean. there is an accurate zoom that you can run after verify is complete, or use stock models to verify individual sections of the part. the bigger the stock size, the more choppy the verify results

if you do a lot of simulations of any kind that is where I think you will notice the biggest impact with computer performance. So if your not doing a ton of Machine Simulations or don't plan on it I think a more budget friendly pc is fine.

100% agree Aaron!

that file will open in mastercam 2023, All X releases can be opened in 2023, its just the V releases that can not

if you want the most control possible, then investing in a 3d mouse like this is the way to go in my opinion https://3dconnexion.com/us/spacemouse/ otherwise you could try ALT+arrow keys, that should rotate the screen in small 5 degree increments.

the sky is the limit with dynamic milling, in my opinion it can be used everywhere when used properly, heck check out what titan of cnc does with this giant heck of a tool here in his vid, he dynamic mills the heck out of this titanium part and you can see the jumbo tool he is using in my opinion good quality tooling always makes a difference, however just dialing in or getting the proper speeds, feeds, depth of cut and stepovers correct should allow you to dynamic mill just about any material. But keep in mind there are a ton of ways to use dynamic mill, it doesnt always have to be consitered high speed machining or doesnt even need to use chip thinning with less than a 50% stepover, you can be very aggressive and powermill with dynamic and still see incredible improvements over traditional machining or legacy type roughing operations. sometimes people only think of dynamic milling as running high speeds and feeds with small stepovers, sure that probably gives you the best tool life but can use the path like titan does as well in the vid below with a nice heavy stepover and slower feed its like that saying, i cant remember exactly how it goes but i think its something like "once you go dynamic, you dont go back"

in my experience smaller stepovers with faster feeds result in better tool life than a heavier stepover at a lower feed, i have even seen some evidence of this with Dynamic Power milling where we can achieve really high material removal rates with sacrificing some tool life. So you may get more parts out of the same tool if you perhaps reduce the stepover and then to compensate increase feedrates.

another option would be to set a plane or quick plane off one face, then run analyze draft angle, this will report all horizontal surfaces as a specific color, i think this would work better than analyze curvature would parallelism. just click the little blue rewind looking button when you launch analyze draft angle and it will process the solid with the given tolerance. curvature only reports flat surfaces, so it can prove something flat but not parallel, where analyzed draft angle can be set to a specific plane and can actually give you what is horizontal based on a specific plane

good find! yea i have seen power settings especially power saving settings cause a lot of issues, i think some of those power saving modes or settings drop the pcs performance so much that it can cause issues in specific circumstances, so i always put my pc into take all the power you want mode

i would suggest looking under advanced power settings on the pc under your power options, perhaps the hard drive or something else important is getting shut off or going into sleep or something? Did your IT team implement anything new that could turn something off or time you out after a while?

I liked off topic a ton, its too bad that a few bad apples spoiled it all for us, I really think the majority of us can handle conversations with others on topics we do not agree on, but some people (probably the ones not knowledgeable enough to actually hold a productive conversation on a controversial topic) got all but butthurt or had their feelings hurt and decided its easier to silence people they don't agree with than to try to have a conversation. I do think Emastercam made the correct choice given their options though, because the Socialist media companies like facebook, twitter, etc decided they would just censor and ban anyone they didnt agree with and we couldnt even post truthful info about Hunter bidens laptop, elections being stolen, covid vaccines, etc. even if the information was truthful and valid, instead of emastercam doing something like this they shut it down for everyone which is far better than the alternatives that facebook, twitter, etc. chose. I still hate that the mastercam educators alliance group is on facebook cuz i think they can do a lot better than using the facebook platform. but all in all i hope off topic can return some day -false information, checked by an independent fact checker...

very clever!

Happy new year everyone! Hopefully ill see you all here again in the new year!

it should be the same post, my mistake I didn't see it was resolved. yea what you explained did seem odd, but high speed machining should help for a lot other things too so im glad you were able to find the problem and get it resolved

haha makes sense and i understand Jparis, at least its clear to me that CNC software has been really putting a lot of time and effort into improving the cad portion of mastercam because each release in the past few years has had some great new tools offered, some of its subtitle changes like when they released mitered corner support for Sweep solid or sweep twist and things like that that might slip under the radar for a mastercam user and now with 2024's solid position coming out soon, so I cant give them too hard of a time in the CAD area because its getting better and better each release so at least our and your concerns about cad are not falling on deaf ears
