- I've been tasked with a fun yet challenging part to make, this one's best off made on a fixture I think! This fixture will allow me to have access to all the necessary sides of the stock later on, as well as make holding the piece for the subsequent operations much easier.

I use Datron tooling for all my acrylic work. If you're interested in giving them a try on your own setup, be sure to drop Datron UK an email mentioning Praetex Design sent you for 10% off your first order!

I'll say it again - Datron should be paying you boatloads of money for making these videos! :)
A Praetex video pops up in my notifications, I can't click fast enough! Let's see what the mad scientist is working on today in the lab.
Thanks for more vids, always happy to see what your up to and appreciate seeing your process ❤
I need some of that magic sucking paper, amazing machine broski 😎👌
The vacuum table is so unbelievably convenient
You could easily do that part in two setups, just hold it in the wise in setup 2 already 🙂
@@jesperhagstrom The part is wider than the vise I had to hand. This is pretty much just a 2 op part with a couple minutes for the third op that I chose to keep the vacuum stronger.
@@PraetexDesignaaah I see
As always, very nice job! Would be interesting to know if something changed in your CAD/CAM workflow since you have this machine. Are you still using Fusion?
@@MotoMishka85 Yup still Fusion. I’d say a big change is being able to trust the machine rigidity much more. For small tools that’s allowed me to be much more aggressive and consistent with my cuts.
A big thing has been learning to slow down too. This machine can cut so much faster than I usually show, but in doing that the risk goes through the roof. Since the parts I show on here and IG are often one-offs, it just doesn’t make sense to push. The difference is often only 2-4 minutes, not remotely worth it for a single piece or even just a few.
Nice video. Great Datron machine as well. I appreciate the lack of odd UA-cam background music. Does one get more clicks by putting ASMR in the title? I'm not sure if the actual definition of ASMR is well known. I, personally, have never experienced ASMR watching a CNC-related video. Perhaps a movie trailer or two with the creepy upside-down demon creatures chasing someone down a dark hallway perhaps. That's about it though.
if i could give you two thumbs up, i would.
.... machining accident ?... I'm only running 9 & a 1/2 myself since my one-&-only accident, 35 years ago... 🙄😂
Great 🎉
Nice video! But why are you only stepping down a few mm’s while roughing out the part? Why aren’t you using the full flute length and a smaller stepover? That way the tool would be more evenly used along the cutting edge. Just asking
@@kd_design It’s to reduce the tool pressure, I’m using the vacuum table for this part and it’s not very large. I went with a high feed strategy to keep it as stable as possible
@@PraetexDesign ah ok I understand…That makes sense👌
Hey Mr alex... You're missing some chamfers for full ASMR there... Nice work! I'm missing my M8Cube every day..
Just out of curiosity - why did you choose pocket machining over adaptive on the outside contour?
@@FriedrichKegel Valid question as I normally would. Pocket strategies work well for high-feed style cuts, I would have had to cut deeper with an adaptive path for it to be efficient, which means more tool pressure. If I keep it the same but with a high WoC, it just results in a really long cut without much benefit.
@@PraetexDesign Thanks for the reply!
just woundering but did the cam program not want to do a ramp toolpath on the contour on up one ?
@@flikflak24 The main thing there was avoiding full engagement, I didn’t want a 20mm deep cut on a small vacuum part. I could have ramped down to 5mm but it wouldn’t have really accomplished anything. I’ve also found that ramping tends to leave a worse finish vs leading in on a corner or similar.
whats the model of the wrench you are using for the 5th axis vise?
It’s a Wera Zyklop
how does the vacuum suction work through the sheet of cardboard?
@@korfenkeil the vacuucard essentially diffuses the vacuum and acts like a gasket. The cool thing there is it means you don’t need a perfect vacuum in order to hold parts down, the flip side is you need a high airflow vacuum pump. Wood shops use MDF for a similar purpose with their large routers.
how do you make sure the part is flat on the vise? you only touched off Z on one point.
@@ipadize Normally if it’s an important part I’d confirm with an indicator and then adjust, but for this the last parts are just clearance pockets so it doesn’t matter.
@@PraetexDesign does the control have the ability to check the surface for flatness and then run or stop depending on the flatness requirement?
@@ipadize Yup on the trunnion you can compensate for it, same for rotation.
what is holding the part down?
The vacuum table, through a porous sheet (a vacuum card)
Why saw vertical? Material too wide for the saw?
@@Thewaldo12345 One edge wasn’t flat, vertical was just easier
Love your videos, but I can't read your tool data before it disappears. And your tool description does not work as a code no. I've no idea what tool you are using without google. And as a machinist, I like to know that stuff.
Quite presumptuous, no? If every single bit of info about making the part was in the video you could be certain that there'd be complaints about too much fluff being shown. If tool data is something that YOU want to know, you've been given all the info required to take the minimal amount of time to look it up.
@@footpetaljones I agree with Anthony.... 😕
i'm not sure i get the point of these machines, a haas minimill could rough this faster and is way cheaper, and cuts harder materials too,
Bear in mind the roughing time for this was both minimal and not even close to the capacity of this machine either. All that time saved would be thrown away doing the finstack with a 12k spindle on a sloppy machine :/
For the love of all that's holy, please stop slamming things on that surface plate. 😳😳
@@st3althyone Don’t worry too much, it’s a low precision one just for general shop use. The audio is also tweaked a fair bit remember.
@@PraetexDesign Sorry, mate, I just hate seeing equipment being abused. XD
You know ASMR? this isn't ASMR. this may be anti-ASMR.
@@HairyStuntWaffle You’re telling me you don’t go to sleep to the sweet sound of high speed machining?
