Why Tapered Ball Nose Bits? - Part 34 - Aspire and VCarve For Absolute Beginners
More down here ↓↓↓ Click SHOW MORE!
This is the 34th in a series of videos geared toward the person who has never worked with CAD or CAM in the Vectric Software before.
In this video, we’ll start an examination of Tapered Ball Nose Bits for 3D Carving.
Tapered Ball Nose Bits (TBN) are fantastic for 3D carving, but they’re also very pricey when compared to standard ball nose bits. Enough so, that I get asked whether or not they’re actually necessary for 3D carving.
In this video, I’ll show you some of the basic differences between a TBN bits and a standard ball nose bit. We’ll get into why you would want to use a TBN, and when. We’ll take a look at some design considerations you’ll need to take into account, then go over toolpath strategies to discuss why I tend to use a Raster Strategy over an Offset Strategy. I’ll then show you the easiest way I’ve found to enter a TBN into your Vectric Tool Database, and we’ll go over the various criteria you’ll need to know to enter the tool into your tool database. I’ll even wade through the whole “feeds and speeds” minefield, and give you my unsolicited opinion.
As usual, if you have any comments or questions about anything I covered in this video, please put ‘em in the comment section below.
On Sunday, October 27th, 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!

This is exactly what I think is missing in vectric software. You should really have the shank and cutter dimensions in the tool database and maybe even the tool holder dimensions like fusion 360 has. It can calculate collision and you will know if it fits. I've seen a post about this where vectric says "you should know if the selected tool is capable of doing the job" though I think it's safer to let the software help you by warning you that it might not be the right tool for the job. Maybe someone with a more direct line to vectric can ask them once more.

Fantastic Series, I'm making my way through EVERY one of them, they are a GOLDMINE of useful info on CNC machining in general and Vectric in particular! Best part is that you actually SHOW every step needed to do what you want to do, A LOT of other channels assume too much and leave out the details. Thank you Sir! BTW, @19:34, are you a Led Zeppelin fan? Several bookmarks for Trampled Underfoot! lol More props to ya Mate, ROCK ON!

Another use for the tapered ball nose cutter is for doing male inlays. If I am using a 1/16 diameter taper ball nose cutter, I cut the female pocket with a 1/16 diameter regular cutter about .005 less than the thickness of the male inlay. I make a mirror image of the male inlay and run the material for the male inlay through the planner on a planner sled. If I am using a 1/16 diameter ball nose cutter, I set my cutting depth about .010 deeper than the thickness of the male inlay material. Because of the mirror image the top surface of the inlay, will end up at the bottom of the female pocket. The taper on the cutter gives you a lead in on the male inlay and because the tip of the ball cutter is smaller in diameter that the cutter you used for the female pocket, you will get an interference fit at the top of the inlay. At the glue up I put wax paper over the male inlay and clamp a board that covers the entire inlay.Works like a charm. You might have to change the depth of the ball mill depending on the hardness of the materials you are using. The harder the materials, the less interference you want to have.

@MarkLindsayCNC 4 года назад

Oh wow! I'll have to give that a try. When I finally get around to doing an inlay, that is. Hopefully pretty soon. Thanks for the tip!

Great video and thanks for your insight on when one might want to use a tappered vs regular ballnose. Helped a great deal. Also appreciate showing how tappered ballnose tools are added to the tool database. As they say, a picture (or in this case a video) is worth a thousand words.... especially when you get to the tool diameter vs the tip diameter/radius. New in version 10, now when giving names to new tools I add, I find myself inserting the naming variables (right click when editing the name) which pull the actual values from the tool data entered below. That way the name remains in sync with the actual tool data. Again thanks for all your work and sharing.

@MarkLindsayCNC 4 года назад

Thanks for that tip! I usually name my bits differently than I demonstrated in the video. I didn't name that bit the same way I usually name my bits to make it easier for me to go back and delete after the video was posted. I don't like having a bunch of tools in the database that I don't actually own.

@Mr_Chuckles 2 года назад

Handy trick -> Raster cut *with* the grain to better hide the cutlines.

@MarkLindsayCNC 2 года назад

That works in some applications, but not so much in others. It also depends on the material. Some brittle woods like Wenge don't like running with the grain. I get my best results running at somewhere between a 40° and 45° angle to the grain.

Man I wish I'd known Whiteside had their tool dbase for Vectric. I've been manually inputting these things like an idiot. Now I'm going to go download and overwrite what I put in by hand because I'm certain some of it is wrong. Especially with the tapered 1/16 and 1/8 that I have and probably for the engravers I just put in the other day.

@MarkLindsayCNC 3 года назад

Before you change anything, import the TOOL file and look at it to see if there are any dramatic differences. Remember that the TOOL files supplied by the manufacturer are guidelines, and the feeds, speeds, and pass depths may not be appropriate for your machine. Take all of that into consideration before you use that TOOL file.

Love your videos, to the point, I downloaded Amana Vectric tool data base. bit 46284K has a tip radius.of .06285 should thar be .03 radius?

@b-radg916 Год назад

I may have missed it, but is there a reason to use a standard ball nose over a tapered one? If there is, I can't think of one.

@MarkLindsayCNC Год назад

Mainly when you want a radiused edge and straight sides in a pocket - similar to using a bowl bit, but a smaller diameter. They're also used in making coves. The larger surface area means you can use a slightly larger stepover.

@chrispelletier3661 Год назад

Hello Mark, I want to use MDF for some 3d carving. I can not find any info on speeds and feed on MDF using tapered ball nose bits. Can you help me out? Thank you very much for all your videos Chris

@MarkLindsayCNC Год назад

The best advice I can give you is to treat MDF as you would a hardwood like maple or cherry to start, then fine tune your speeds and feeds from there. There are just too many variables to be able to give you any concrete numbers.

@davidlister2438 4 года назад

As usual, some great information! I'm a new (6 months) hobbist using Vcarve Desktop on a Piranha XL. I think your comments about adjusting feed/plunge rates on the fly in the shop would not apply in my case. The Piranha XL does give me the option of cutting back the speed from 100% to anything less. Would I be right to go with a higher feed/plunge rate on the individual bits, then start out with a lower speed on the CNC - say 25% or so? Thanks, Mark - you videos have been a great help!

@MarkLindsayCNC 4 года назад

Thank you, David. You could give that a try (in some scrap material, of course,) and see if that will work for you. From the way you're describing it, it sounds reasonable to me. I would be hesitant to start out fast, then try to slow down. In starting slow, you can increase to the point that you start to get chatter - well before you risk damaging the bit, machine, or material. If you start out fast, you may already be beyond that point - and once it's damaged, it's too late to slow it down, and there's no way to reverse most of that damage.

@travismurray9160 3 года назад

Question for you bout using tapered ballnose bits. How much do you usually take out per pass in hardwood using the 1/4" to 1/16"? 1/4" to 1/8""? Thanks.

@MarkLindsayCNC 3 года назад

I have my tapered ballnose bits set to take off .1 inches per pass. Since I do a 3D roughing toolpath with a machining allowance of anywhere from .02 - .03 machining allowance first, most of the material is cleared away, so it never actually cuts out that much material.

@mr.p9882 2 года назад

Are you familiar with idcwoodcraft tools? Are they as good as Amana? Have you tried them? I'm thinking of ordering some but I really need to know if they will hold up as well as Whiteside and Amana...

@MarkLindsayCNC 2 года назад

To be honest, I've never tried them, so I don't have an opinion. Sorry!

@Dave-ni4vg 2 года назад

I don’t understand when you look at the specs it says 150 160 ipm for the tapered bit but I don’t think anyone runs it at those speed when 3 d carving?

@MarkLindsayCNC 2 года назад

There are a lot of variables. It depends on whether you run a roughing pass or not, the type of material, and your machine. Some folks with very rigid machines do run them that fast.

@p8ntblr1 2 года назад

I recently purchased a Amana 46282-K 1/16" tapered ball nose bit. 1/4" shank. I downloaded the amana tech sheet for the tool data base and notice the pass depth is set at 1.022. Is extremely high pass depth normal?

@MarkLindsayCNC 2 года назад

No, it isn't. I don't know where they got that Pass Depth, but that's a good catch on your part. I have the Pass Depth for my 1/16" Tapered Ball nose set to .1 - and even that may be a bit too aggressive. I almost always use my smaller TBN bits in conjunction with a Roughing toolpath (with a machining allowance of .025) so they never get close to taking off .1 per pass.

@steinaralpenmob 4 года назад

Thanks again for a great video Mark, I always learn lots of news from your videos. But I have one "problem" I use metric, do you know of an easy way to convert from inches to millimeters when I need to create a new tool in my database

@MarkLindsayCNC 4 года назад

Thank you! I released a video this morning that might help in setting up a new bit in the database. Just remember to work in the Metric tools category and set the Units to Metric. Here's that video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-42v6KC4UPAg.html If all of the dimensions are in Imperial, and you need them to be metric, type the Imperial measurement into the applicable box, followed by *m then hit the = key on your keyboard. I did a video on this 2 years back. I use a file in the demonstration, but it's the same formula. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KE4kxHxE95g.html

@tonyb6617 3 года назад

Mark ... great video. I have a question. Wouldn't using a 3D roughing pass have a cycle time benefit over not using one. Would it make sense if you have a larger depth to always use a 3D roughing pass?

@MarkLindsayCNC 3 года назад

Yes, you should use a 3D Roughing pass if you're carving anything with a deeper cut. My point in saying that in a lot of cases a roughing toolpath isn't required was to show how the bit worked vs a straight ball nose bit. I use roughing toolpaths almost all the time. There are cases where the finishing toolpath isn't removing much material (equal to the bit's cutting diameter or less,) and that makes the roughing pass unnecessary. It's just good practice to do a roughing pass to make things easier on the finishing bit.

@b-radg916 2 года назад

@@MarkLindsayCNC: You said you almost always use the Raster strategy for your 3D Finishing toolpath. What do you think about the 3D Raster strategy for your Roughing toolpath? On a couple tests I did it was faster, and seems like it leaves less for the finishing bit to remove too. Thanks!

@hmatyas1 4 года назад

How can you skip the 3D roughing tool path. I can see how you could use the tapered ball nose bit for both the roughing and finishing cut. But I do not understand how you could skip it. Thank you. Harvey

@MarkLindsayCNC 4 года назад

That's the purpose of the tapered ballnose bit - to allow you to skip the roughing pass if you wish. The tapered cutter will clear away the material along the face of the material being cut before the tip gets there. It basically does a roughing and finishing pass all at once. You still have the option of running a roughing toolpath if you'd like. Some people prefer to do it that way. With a tapered ballnose, a roughing pass is usually not required, unless the model is placed in the material so deep it's beyond the cutting length of the bit. In that case, yes, you'll need to do a roughing pass.

@hmatyas1 4 года назад

So basically in Vcarve, would you do the roughing and finishing simulation with the same cutter and then just skip the roughing tool path and go straight to the finishing tool path? I'm basically afraid that if I skip the roughing tool path that I will break the bit. By going striaght to the finishing cut, 1) You avoid a total change, 2) avoid rezeroing the bit, 3) save the time needed for the roughing cut. Have you done a video showing how this is done? Thank you for your help. I'm still learning how to use the CNC and the Vcarve software. Harvey
