Mastercam OptiRough Toolpath Video 1

- Taking a VERY in depth look at the OptiRough toolpath in Mastercam. In a nut shell, Optirough is the similar to the 2D Dynamic Mill toolpath with the added ability to cut 3D shapes.
With the 3D cutting, we have a choice between stepping down in small increments, thus keeping to the rough cut close to the net shape, or a large step down followed but step ups to again, keep the cut close to net shape. We'll look at both strategies in this video. One reason you would pick one method over the other will result from the tool that you have available for this roughing toolpath. Typically, endmills will use the large step down with small step up, and high feed cutters will use the small step down only method. As with anything in machining, this is a suggestion and not a rule.
To have a full understanding of how to use this toolpath, I would suggest you go through the 2D Dynamic videos and course first. Some of the same settings and strategies exist in that path and will not be explain in depth in this series. A link to the first video in that series...

There is a lot to cover in this toolpath, from speeds and feeds, cutting strategy, stock settings, boundaries, filtering, post selection, etc etc...so these videos are a bit lengthy. Grab a coffee, or a beer, and get comfy. You're gonna be here a while.

Thank you for the APP. Helpful
amazing, thnx, for all info.
Your welcome!
좋은 영상 잘보고 갑니다...
hi sir i have a problem in regenerating the 3d hogh speed toolpath some computation error is occuring is there any settings to change for that case
Hey this is awesome video I save this to one of my playlists to show my guys later. You did mention though that you're going to make a video 4 g code optimization. Are you going to get into Arc filtering settings because I've been always wondering about that and I haven't found good information about what's the best setting for each situation...
Yes. We'll be adding arc filtering to this toolpath and seeing it's effect in the next video.
Mike Wearne great! Can't wait
tnx
Your welcome
so maximum z depth is a saftey feature? ? nothing to do with your geometry and how you cut?
Hi, I closed the tab indicating level, plane, tool path which is located to the left side of mastercam 2018. how can I make it visible again?
Along the top of the screen, click on the VIEW tab and then click on Toolpaths.
thank you very much
Actually, I am a subscriber of your 2020 course here in Canada, and in a few sections that you mentioned, Arc Filtering is one example, there is a detailed explanation of each of them. Actually, while there are few explanations but is not covering all.
What section of arc filtering were you looking for more information on?
@@CamInstructor In Dynamic Milling section when it goes to Arc Filtering. While there is a general explanation about it but it does not go to option and its application. This is true regarding other things you mentioned in the Cut parameter. Anyway in the Mill 3D lesson 13, Exercise 13 or there few dimensions are missing or things are not quite right. It is 2 days I am trying to make the loft solid that comes all distorted even though I make them the same amount of entities.
That lesson you need to pay attention to the syncing options used and the starting point/direction of your chains.
Again, Lesson 15 on 3D for 2020 course. In the cut parameter on Overthickness and Bitangency, you mentioned there are full videos about them. I am struggling to see where is it still.
@@farhad64it These are questions best asked through the Ask Instructor function on the website. That way I can upload supporting documents or videos.
do you have any videos on impression and boolean features ?>
Yes. One of the livesteams I used boolean for a softjaw. Its not a full 'how to', but its talked about a bit.

I cant see that becous not clear
that’s a long cycle time 👀 The strategy is very good no doubt , but the time is just crazy .
Big parts take time, even more time if you need 3D motion. Material will play a big roll too.
CamInstructor yeah i know , tolerance also comes into play
CamInstructor if you have linked in let’s connect ! i would like to know more about opti roughing
interesting video. also kind of a bummer, we have older machines where i work. im the lead and mastercam is on the boss' radar but the late 90s haas machines we have contain 1 mb of controller storage. /sighhh what am i to do with individual toolpaths that are gonna be several megs each, hahahah. oh well..
Can you use “drip feed”? We have older machines also and send all code over via RS232 serial ports. If the file is too big, we use the machine’s DNC option with the highest baud rate we can get away with.
Is there a way to learn what does every single option in parameters mean?
Yes! Watch all the videos. If you have questions, ask away!
We also have some free courses on our website you can check out.
@@CamInstructor thank you for your answer.
Where is stock to leave ??
Stock settings can be found on the Model Geometry page. You have options for Walls and Floors there.
Is there a way to automatically generate "tabs" ? Say you wanted to hold this part in the stock for secondary operations on the bottom side? I realize most of the point of this video is to remove all the stock...LOL!
You could have extra stock on the bottom for holding and just stop the toolpath in Z before machining it away. If you want tabs, you could model some in and then OptiRough could see them and machine accordingly. 2D Contour has an option to auto generate tabs which could also be an option.
Its not a perfect program. U can optimize the cut order and just draw a boundary using bounding box. No need of selecting stock and stock modal.
Sree Kumar that’s what i was thinking as well , just draw a bouncy box where the stock would be and then create a tool path based on that boundary box
I can create a stock model much faster than geometry to represent stock. Stock model, 3 mouse clicks, geometry to represent stock, 10ish...and that would be for simple stock. Anything complex and the difference grows more. Also, if you change the stock size, updating the stock model is again very few clicks and the toolpath is tied directly to it...if you create new geometry you have to remember to rechain in the toolpath. Its all personal preference as there is always more than one way to do something in Mastercam...the point of this video was to work through many options and see the different results.
As far as toolpath optimization, there are 3 more videos in this series looking at optimization of OptiRough. This is only the first video and the part is not done yet.
CamInstructor there’s more than one way to skin a cat and i respect it
bad video quality
