they are documents lol.

Thanks Randy!

This all has to do with feed rate when grinding. I have made tool that hold up better than large manufactures tools. I was making some ball mills for a customer that held up better than the Guhring ball mills they were using. They even sent on of mine to them for them to duplicate. But you know the only difference (in my opinion) is in order to manufacture their tools for the lowest price. They feed the grinding to fast to reduce cycle time. I always feed the primary cutting edges slower. That takes more time but it makes a better tool.

@@EdgePrecision exactly if the finish on the tool is pristine it will not Fail like others!

They make the in different lengths. The end the mounts in the tool holder has a ER end and the other has a srink connection. The one in this video is a .125 shank and projects about 1.5 inches out of the ER collet chuck. Do a search “Iscar ER srink in” you will see them.

Peter 🙂 I'd hazard a guess you're thinking of WT&T?

I never enter code manually.

Yes if I need a external left hand or a internal right hand #4 insert I'm good Thanks! As to the material? I made the blanks many years ago so I can't be sure. But I usually buy O-1 Drill rod for this purpose. So I would assume that's what I used.

I'm not exactly sure what you are referring to? This grinder is not a surface grinder. It is designed to grind tools on. Like endmills. Its not really meant to do what I'm doing here. But I can make it do this.

@@EdgePrecision I believe @Kainafar is referring to the simultaneous milling that you did (the "adaptive" path) where it was mostly the C-axis rotating left and right. I would expect it to be pretty flat but I'm also curious if you've ever attempted to quantify it.

@@dumpsterdave3710 Not really because it’s usually used for roughing. I don’t see why it would be flatter then any other milling cycle.

@dumpsterdave3710 A C axis lathe without Y relies on that style milling for everything. We just got one and I've done some curved surfaces but nothing flat to run an indicator across. It's a compromise and I expect it to be less flat than a "true" axis, which is probably why Peter only uses it for roughing.

Yes but it’s the machine I have.

You have a really big machine. A goliath.❤

Much easier to make small parts on a big machine than the other way around

That Could be possible. The only bar I could find was 1.500 in diameter and kind of expensive. I already had some of these blank shanks that I turned for this purpose, for the grinder. With .750 shanks. So really I didn't have to buy anything except the clamp. Also I thought it would make some good KZfaq content.

@@EdgePrecision That makes sense, I kind of figured being a off hand bar it would have been pretty pricey or not stock. Glade you made the video then!

All I know is they gave me a sample insert they have been using. All I did is duplicate that. If it doesn’t work it’s on them.

@EdgePrecision thankyou for making these, once again!

Thanks Jeffrey!

The tap extension I used in this video is a Ritmar brand. If you do a search for that name you will see them. Here in Houston,Texas I buy most all my tooling from Bass Tool. I have shown also how I make one in my video titled "Copper Part-1 Setup". The Ritmar one works kind of like a collet. On my shop made one I hold the Tap in it with locTite. So to change the tap I have to heat it to break the LocTite bond.

The coolant system on this machine is quite large. But things do get warm. So constant adjustments to offsets are necessary to hold close tolerances while grinding tools.

On this grinder, it has a conversational type format on the control for its grinding cycles. Foor this tool I would specify a profile in 2D and it figures out the rest. Because it is a five axis machine with complicated movements I really never do any manual programming. Except maybe a very simple MDI move. Because I don't have a proper tip for the tool probe, to probe left hand tools. On this setup I did have to establish the rotational zero (A axis) for my insert's shank. I was able to indicate it and set a fixture offset. This then required me to do a MDI to bring the A axis to its zero for a verification of that zero point. But all the programming is done in the control because it is to complicated, if not impossible to program this manually. With the clearance angles of the tool. I know there is probably a way to calculate these paths (Because the control does it). But that's way beyond my mathematical ability.

​@@EdgePrecisionit would almost certainly be way too time consuming if you did have the maths and render the whole affair unfortunate and useless for anything other than personal satisfaction.

@@EdgePrecision I saw you programming the spacial shape endmill in one of your videos I just didn't know that you could do this type of geometry on inserts conversationally that's why it would be interesting to see the programming on the control even though they made very small quantities of that machine and we probably won't work on that control anyway I hope it is not asking too much.

Yes it can be done. The software is called Num Roto. That kind of gives the impression it's for rotating tool grinding. Like Milling Tools if you will. But it can be made to do this. What I'm basically doing is defining what they call a form tool but with a single flute and no helix. So if I define the profile in the correct location of the insert in my tool holder the machine will grind it in that location with the relief angles and everything. What is important is getting that profile in the correct location. So in these cases I model the tool holder and insert in the Cad software with the unground insert. Then save a .stl file of that for the simulation on the grinder. That way when I make the program and simulate it on the control. It shows everything in the correct place. Pretty much if you get the simulation correct thee grinding will be correct. With very little changes.

@@EdgePrecision I knew there is some getting around to do this thank you peter for your answer I got it now you don't have to do a video for this and it is awesome that you are replying to complete strangers and taking your time to compose such detailed answers I don't know how to thank you if you need anything considering FEM simulations, vibration analysis or impeller geometry and design you can come to me as I shine in those departements since I studied aeronautics, I know a fair bit of machining too but hey I'm here learning from you, thanks again for everything

It holds 80 tools.

Enough to make anyone feel inadequate 😂

The manual chucks I'm using on the Mazak are Bison brand.

Are you referring to machine parameters or the in a process TPC parameters? On the machine parameters I rarely adjust them except maybe for calibrating a tool setter. Witch I don't use anyway on my machine. I would not recommend changing them unless you know exactly what you are doing, and have a very good reason for doing so. On the TPC parameters in processes? It's been so long sense I have really used Mazatrol's conversational part of the control. Truthfully I would have to relearn most of what I have forgotten as well. There are guys here at Centerline (The place my machines are in. See my "Shop Tour" video). That are really, really good with Mazatrol. But I don't us it on my Mazak except to bore soft jaws. So I have a saved program just for that. I just change the dimensions in it to the size I need. I would do a video but in this case I don't know if I could share any real useful information on this if that's what you are referring to? Or maybe you are referring to setup and tool data/entry's now that I could do a video on. Thanks!

@@EdgePrecision No problem! Thank you for your reply about that. I brought it up because I've spoken with some people who do adjust the machine parameters quite a bit- it seems risky to do it in certain cases and seems like it requires a lot of knowledge overall. Seems like a lot of PLC and electronics knowledge is required to understand how each "bit" can change the function of the machine in some way. Very complex side of things but also very interesting. Also figured a lot of Mazak users that run Integrex and Variaxis machines might run into a lot of situations where they would have to make parameter adjustments to essentially "teach the machine" to behave and run in certain ways during different modes of operation and set ups.
