In this video, I’ll show you how to use the Rest Machining technique in Vectric Aspire software to reduce machining times when carving a 3D Finishing toolpath. I’ll show you how I created the first 3D Finishing toolpath for the model, Previewed it, then demonstrate how to create a component from the 3D Preview window. Then I’ll demonstrate using the Trace Bitmap function to create vector boundaries.
Then I’ll calculate a second 3D Finishing toolpath that will carve away the remaining stock within those vector boundaries, and preview it.
Along the way, I’ll also show you some critical things to watch out for when tracing the bitmap and calculating toolpaths.
As usual, if you have any comments or questions, please put ‘em in the comment section below.
On Sunday, April 19th, I’ll be hosting a LIVE Q&A session, where you can ask your questions pertaining to anything I covered in this video. That Q&A starts at 3 pm Eastern time, Noon Pacific time. Hope to see you there!

Mark, you are a CNC National Treasure ! I thank you for your great videos.
In addition to time savings, bits of small sizes are consumables - can't sharpen them. So rest machining cuts down on their cut time and the amount of material removed with each pass which extends their useful life. Thank you again.
Excellent point! I'm all about saving money where I can, even in small ways. Keep the tips like this coming, and thank you for checking out the video!
Oh man... This is my new favorite function. I do a lot of 3d and this is always my sticking point. I won't have to manually draw around these areas anymore.
Excellant...I was doing a roughing pass and 2 finishing passes that addled up to 9 hours no matter what I did to step over or feed. Now it is down to around 3 hours. Not as sharp as with a 1mm bit but it looks good still and I dont have to worry about my machine burning up. Mark you always have good tutorials. Thank you!
Fantastic job Mark. I'm getting back into CNC after a 4 year break and your video's have really accelerated my learning curve. Thanks so much for taking the time to do these!
Great work on this one Mark! I love reducing machine time with clever CAM techniques.
Thank you, Cory! Do know that in Version 11 of Aspire, REST Machining is now built into the 3D Finishing Toolpath. So this video is basically for folks who use Version 10.5 and earlier.
Completely fantastic - been trying for hours to achieve this level of clean up in less than silly times. Thank you so much for this video and excellent tutorial !
Hi Mark, just now getting my feet wet with 3-D modeling and it's a Pepsi challenge. Lots for me to learn and I'm enjoying the process. Thanks for another informative video.
Thank you Mark. It’s a shame that this only works in aspire. I have vcarve pro and am struggling to do the same. The anchor is similar only it is of the Navy Chief. I remember you telling me during a Q&A a few sessions ago that your Dad was a Seabee. Hoorah Seabees! The Chief anchor has a chain that is what I am working to get the most detail out of. It just isn’t as user friendly to me. It may just be that I don’t know enough. I purchased it from design and make. I applaud you for what you bring to your audience. everything I’ve learned about this software has been by watching your videos and trial and error. Thanks again.
I have Aspire and never knew this was even an option (until now). My normal method is to manually draw lines around these areas and then perform the smaller bit toolpath. It's a good workaround, but not as good as this.
Hello Fransisco, just a thought, maybe upgrade to Aspire? If it will save you a bunch of time it could very well be worth the investment. Good luck
Thank you for an excellent presentation....this will be very helpful for me....
Thank you for this ! I surely did learned something VERY useful today !!!
Thanks Mark, Excellent Tutorial.
Thank you very much, Peter! I do appreciate it!
Great tutorial Mark! Thank you for sharing!
AWESOME! As always! Thanks Mark.
Awesome Mark. I recently purchased Aspire 11 and am looking forward to trying this out. Keep up the great videos.
Do know that this method is for older versions of Aspire. Version 11.0 has Rest Machining built in now, so this method is no longer necessary. You now simply add the smaller bit to the toolpath, and the software does the rest automatically.
@@MarkLindsayCNC Either I am doing something wrong, but when I add the second bit, it seems to take even longer, because it still seems to carve over the whole project
Very very great tutorial, thanks a lot Mark :-)
Now that was awesome excellent
Mark, another great video! What do you spin these discs/bristle brushes with... drill, die grinder, dremel... what speed will they handle? BTW, one reason i love your videos is because you get right into it... NO LONG BORING INTROS ETC.!
Thank you, Lyle! I don't care for intros much, so I use the Makers Media Network splash screen to promote the network (a GREAT collection of people, by the way,) then get on with it. The nylon sanding brushes have a 1/4 inch shank on them and get chucked into a drill. If it's a short sanding session, I use the cordless drill. If it's gonna take a while, I use my corded drill. The ScotchBrite disks get stacked on a mandrel (3 disks at a time) and are used in a Dremel (or similar rotary tool.) Some packs of disks come with a mandrel, and some don't, so if you don't have the mandrel (basically it's the same mandrel used for cut-off disks,) look for the disk pack that comes with one. I'll talk about them more in today's Live Q&A.
Another very informative video Mark. I do not have "Aspire" YET.... but, when I trace bitmap in V Carve Pro, I zoom in on my troubled part of the picture ( can get better/closer precision ). I did not know that you could use the arrow keys to adjust it, I always use the mouse wheel. Thanks for sharing all the knowledge.
Thank you Troy.
Thank you, much appreciated
Good Video Mark. Not sure if you will get this message because this video is from 4 years ago and on Aspire V10. With V12 out I will be looking and hoping that you can do another Rest Machining video as an update with some of the new and changed features in Ver 12. I have to admit with this 4 year old information , I was able to muddle my way in V12 somewhat to get a better finished product with a little less carving time. At this point there is not many video's out on rest machining that I have found.
If rest machining is not available in VCArvePro, why the option does appear in the finishing toolpath configuration?? Does it make any difference at all if we set it to fine or coarse, or if we change the value?
This video was made in April of 2020, using Aspire Version 10. The use of multiple bits in the 3D Finishing toolpath was not an option in Version 10, so Aspire users had to follow this procedure to use REST Machining. The use of multiple bits and REST Machining was added to the 3D Finishing toolpath in VCarve and Aspire starting with Version 11. The method I demonstrate in this video is still not available in VCarve, and should also be considered obsolete for users of Aspire Version 11 and newer.
As for the Fine to Coarse adjustment, it does make a difference. Try calculating the toolpath with the slider moved all the way over to Coarse, then Preview it. Look at the Toolpath Summary and take not of the Machining Time Estimate. Now move it all the way over to Fine, recalculate, and Preview it. Now look at the Toolpath Summary and compare the Machining Time Estimate. You'll see the difference for yourself. The project will determine where you set that, based on how close the project is going to be viewed from. If it's 10 feet up from the ground, you can get away with a coarser level of detail. If it's going to be held in your hand or seen from up close, you'll want a finer level of detail.
Mark:
In case I don't get to sit in on your live broadcast this pm, I have a few questions, if I may:
1. Why is the dish shown as an "add" in modelling and not a "substract"? Since it takes away from the surface, I would have thought it would be a subtract.
2. Why is no zero plane needed to define the edge of the dish? In previous tutorials, I came away with the "knowledge" that I always needed a zero plane with a dish.
3. Could this be done in VCarvePro by choosing the dish clipart and the anchor clipart as separate models, then using a large bit to do the dish and the small bit to do the anchor?
Thanks again for taking the time to do these videos, Mark. Although I have learned a lot from them, my questions clearly show that I have much more to learn.
Grant
Thank you Grant! Here you go:
1.) Because the model is being added on top of the modeling plane, and I want the anchor to project up from the base of the dish. If I set it to Subtract, it will carve the anchor into the dish. 2.) I could have added a Zero Plane over the top of the model, but to avoid confusion, for this demonstration I didn't want to keep adding steps. Yes, a Zero Plane should be used if you're going to carve a dish like this. 3.) Try it. You'll have to create vectors around the dish and the anchor, then carve away the dish, machining to the vectors around the dish and anchor, then carve the anchor to the vector around it. Give it a shot and see how it Previews.
Awesome
Thx Mark. I am a beginner in Aspire. Could you do a video on node editing where a bounding box includes text that needs to be curved instead of staying straight in the box?
I've done 6 videos on how to apply text to a curve. Here's a playlist: ruclips.net/p/PLLuYLaC3-QROXGmO0E0r_fxmOPnnl16bQ
How come you skip the roughing and go straight to finish? there's 0.38" to dig out & you do it in one go
I skipped the Roughing toolpath for demonstration purposes. Whether I did a roughing pass or not was irrelevant to the REST machining process. That's what I was trying to demonstrate. As for the Roughing toolpath itself, many people skip them and go straight to the Finishing toolpath on models that cut a lot deeper than .38 inches. It depends on the rigidity of your machine and the power of your spindle.
@@MarkLindsayCNC Interesting. Thanks for the reply
How many tools can you use with Aspire rest machining??
Can you start out with a ½" end ball end mill and reduce it to a ¼" ball to a ⅛" ball and finish with a 1/16" tapered ball.... like in Fusion 360 where each smaller tool only cuts what the previous tool couldn't reach???
I've never explored how far you can go with REST machining. I guess if you have the time, you can do what you're asking. Personally, depending on the size of the project, I'd just go for the 1/4" ball nose, then the smallest bit I need to finish the job and get good detail.That's just me, though.
what does the control key add to the selection?
It doesn't add anything - it creates a component out of ONLY the parts within the model that the larger bit didn't cut. If you don't hold down the CTRL key, you basically make a copy of the model. Try it.
I didn’t see how you scooped out the part under the anchor.
I didn't scoop it out. That's part of the model. If you look in the Clipart folder of the Clipart Library, you'll see 3 versions of the anchor model. One is just the plain anchor, the second is the anchor in a dish (that's the one I used,) and the third is the anchor recessed in a shape that looks like it was hand carved into the material. I didn't have to scoop out anything because it was already modeled that way for me.
this lowkey hard
This is stupid. A $2000 program can’t do automatic rest machining?
Well, you're watching an old video. Automatic REST machining became a part of the program in a later version of the software, and is standard. This video was made to demonstrate how to do it on older versions, prior to that addition.
@@MarkLindsayCNC yes. I came back here to update my comment after learning that you can drag multiple tools into a path and it will deal with it.
