Maximizing Work Envelope by Machining Removable Tool Setter

Why you do not using the digital probe Syil offers?

Very nice, I have the X7 and am doing this for sure, another reason for me will be to keep the tool setter away from coolant and chips when not necessary.

Now you have a product already!!

It would be a good video on how to calibrate that tool setter.

May have to watch for chips sticking to the magnets but otherwise, very nice.

whats the biggest roll tap those machines can do. (thread forming)

Отличная идея. Спасибо. Много интересного нашел на вашем канале.

I would suggest some 3D printed covers for those to keep them clean

I came for the vulgarity I stayed for the precision. Problem, idea , execution, problem solved, feels great! Good job.

this is dope

What is the fluid that you used for tapping?

Hey dude, what Matercam toolpath did you use for the beginning that was like surfacing the angles in?

I’d print a chip shield so that chips don’t stick to the magnets every time it’s on there. Or redesign it so that the magnets are more recessed and shielded from chips sticking.

Great prototype

That’s a nifty idea. I’d like to have one for my machines at work.

Great idea for a simple part and something very useful! Great video!

This design is great, but it is technically over-constrained. With four lobes, you introduce a sort of rocking along your perpendicular axes if your mating surfaces are any less than perfect.

Three lobes would make for a proper kinematic coupling, increasing your stability and repeatability with less strict tolerances required on the final part.

How do we find your shop ? Hi from the land down under

I see one disadvantage - the base is not protected against dirt and mechanical damage. I suggest adding a fourth element - a plug.

Great idea! However this design is subject to repeatability loss from surface deformations and wear due to over-constraint. For this application an exact constraint kinematic mount is best. Kinematic mounts remove exactly 6 degrees of freedom, no more, no less. When properly implemented, they don't suffer the repeatability issues associated with over-constraint. Two classic kinematic mount types are the Maxwell and Kelvin. For the same reasons expressed in this video, we designed and ultimately patented a Maxwell type kinematic de-mountable tool probe mount that will repeat to a few microns or less. Check out our system if you dont want to build your own.

Thanks Jessie, one of the best videos you guys have done in a long time. Back to basics, well presented, that was great. X5 handled the steel well.
Any chance this part can be downloaded as a CAD file?

I built a different design base for my X7 tool setter. I do not have a regular need to remove the tool setter (but I can) but the original position takes up too much table space. I see that your tool setter could be moved in the Y direction. The edge of the setter base can be moved in the Y direction so that it is about 10mm from the table edge. My base raised the tool setter by 60mm as the X7 cannot measure very short tools with the original configuration. Also a design improvement/requirement is to relocate the mounting bolt. Additionally I moved it to the left outside the tool setter base. This way the tool setter can be moved as an assembly without interfering with its calibration. Moving it back into position is easy as there is a calibration program that re-establishes the position of the tool setter. In summary move tool setter in Y direction, raise the setter and use a single hold down bolt outside of the tool setter to the left in the dead zone. (If a job interferes with the tool setter just slide it to the left within the dead zone.) There is about 150mm of unused table space on both ends outside the machining envelope in the X direction. Traditionally the vice is mounted in the Y direction. With my 4th axis permanently fitted, I find it easier to quickly mount a 100mm vice on centreline in the X direction. (I still have the option of fitting my 150mm vice in the Y direction.) As the 100mm vice has a longitudinal key that fits into the center slot, re-traming the vice is not necessary. This may be an option for your X7. Cheers

If you want to design a mechanism like this that snaps into place with great repeatability, look up "kinematic couplings". It is a method of designing things like those v-grooves so that there is only one way for the part to sit and there aren't any extra forces or deformations that can occur if there's even the slightest error in a design like this.

It can also be done pretty cheap. For example, this could be done even better by arranging 3 pairs of cylindrical surfaces in a triangle on one side of the coupling (cut 3 pairs of parallel slots to half the diameter of a pin, then epoxy the pins in so there round sides make a v-groove like valley), then put 3 spherical surfaces on the other side of the coupling so that they line up in the valleys (drill a hole to half the diameter of the balls and glue them in the holes). These sets of ball and pin kinematic couplings are stupid cheap and take advantage of hardened surfaces and exact constraint to repeat extremely well (easily much tighter than 0.0001") while being wear-resistant and insensitive to machining tolerances.

The magnets shown in this video are a great idea and commercial kinematic coupling often include something like them.

Nice simple DIY version of a kinematic base. Look forward to more convenience/improvement content like this.

Nooooo. Nonono. The optics people have this one dialed. You need 3 groves 120 deg apart on one half and ball bearings glued into the other. 4 groves over constrains the system so it is not a question of if but how much it will wobble, and flat face contacts under low load are super susceptible to contamination error. Your design would be good if you were going for a heim joint that could take high loads when bolted down, but for this application? Trust the laser people.

Great video. And a great holder design with some clever features. Please share CAD if possible. Looks like a nice project.

nice to see how they get scared of tapping in a mill. (could of just used coolant for almost any size tap and slowed the speed to 20 sfm and calc the feed) this is my basic starter recommended for a 1/2 tap. this was not a diss on them. I enjoy the videos they make.

Great video. Print a cover for the table mount so magnetic chips don’t clog up the magnets.

Genuinely one of my favourite videos from you guys. Love it!

Eine Verdrehsicherung hättest du noch mit einarbeiten können, beispielsweise die Auflageflächen außermittig anordnen

I definitely need this for my X7. Are you going to upload the plans?

That "tapping fluid" looks more like liquefied bacon grease.... And rigid tapping has always made me pucker up too. A spring loaded/floating head is easy though, just enough warning to stop the machine if somethings wrong.

Great idea, but what about the swarf getting stuck to it and playing havoc with the repeatability of it?

Very nice design and machining, bravo

Bingo! Nicely done.

Maybe this is a bad idea but could you not make a tapered hole in the table and make a tool holder that would fit in this tapered hole like you find in the spindle and tool holder. Of course this would be done on a much smaller scale as not to interfere with the functionality of the table? 🤔🤔

Very nice! Well executed as expected from Jessie 😁.
The only Fly in the ointment are the magnets in case you want to murdering some steel. I see a lot of chips attaching to your tool setter. Small little disadvantage

Need some Emuge tapping fluid to help get you over that fear of tapping. :)

Lovely job. Thats a great way of getting the most out of a smaller table. It seams likely that ferrous swarf could stick to the magnets on the mount though.

That tapping fluid looked sus 🤨 😂

Why did you have to build that vice? What are the benefits?

If you ground the mating surfaces, would that get you the tenth in repeatability?

Great Idea, sometimes the simplest things just seem to work the best

Awesome video Jessie, I loved it. The removable base is a stroke of genius, and I'd totally buy one with my machine (when the time comes). Ciao, Marco.

Thats shurly the most satisfying clicking sound ever. The sound of a job well done!

Steel chips and magnets.......I foresee inaccuracy in the near future......

Will there be a video of the x,y repeatability???

Awesome work Jessie!

That would be awesome to have!! See but a .0001" repeatability is spectacular!! Especially when you consider the price of the machine! Will mine be ready for pickup by May 2nd????👀👀👀
