who doesn't have a machine like that that makes everything easy and makes your dreams come true in your basement? When I finish building my tiny cnc I will jump for joy!! Great video
I have a smal diy cnc machine and lts so much ful just addining parts and features even 5 axis is a future possibility so prepare yourself for a amazing journey thre is so much to learn
Great video on five axis! YG1 make pretty good carbide drills if you are ever in the need for some. Also, if your budgets allow you to experiment a little with toolholders I would highly recommend Nikken Multi-Lock milling chucks. We had a 2x removal rate increase by changing to them from relatively standard tooling, rumour has it they hold 5 micron runout at 100mm (translated to 4" ha) on the tool. Have you tried pushing a bit harder to find the harmonic regions of the workholding? Sometimes it pays to push the feed a little bit higher to get out of the natural frequency of the setup, although in some cases it does feel like you're going against all logic
Hi John, what was the cycle time of that workpiece? Could you run more than one pice with an endmill? Basically you are using the same endmill on all cutting depth's an i guess this will shorten toollife drastically because the tip of the tool will wear out much quicker. We are doing lots of stuff the way you did it and i can tell you from my experience, that you are very close to the limit with your application. We normally say that you can have a stick out in aluminium of 15x part thickness and in stell we go with 10x part thickness. To avoid the mistake you did simply use a conventional vise and mill some flats on the end you want to hold with your 5axis vise. You get much more rigidity compared to clamping on that hot rolled surface and wont have any problems that there ist not enough stock when milling the part. The downside is that it takes a second setup you try to avoid when using this milling method. I hope you keep improving your machining skills like this. You get better and better from every video and this is pretty nice to see. Greetings from Germany, Nico
This is the first time that I have seen a "clear" coolant. How cool is that? I was also impressed with the amount of coolant flowing and the flushing action it had.
I tried to watch the playlist in the order you worked, but the videos are all over the place. Heading back to the video list to do it manually. No CNC programming here. LOL! Regards, Solomon
Do you think in the future that the use of hydraulic tool holders could become similar to the use of draw bars? It doesn't seem like a difficult concept, the tool holder would need a complete redesign to work in an automated system, and the machine would need some way to control it. But this cuts down on costs, as you wouldn't need a tool holder per tool, but also cuts down on space, as you only need the array of tools, which have a much smaller diameter than tool holders. The only other thing needed is proper fixturing to allow consistent load/unload. Literally the same function of a draw bar, but instead of it being a spindle - tool holder operation, it's a tool holder - tool operation. Almost as if the tool holder is now acting as a collet to adapt the spindle bore to the tool diameter, while also using hydraulic pressure to hold the tool in place: maybe an 'active' collet, as traditional collets would now be considered 'passive'? Say you have a bunch of 1/4", 3/8", and 1/2" tooling, with this system, you would only need the tool holder for the specific tool diameter ranges. Now say you have a square grid of 25 tools each, a 5x5 grid, you would be saving an insane amount of space in comparison to tool + tool holder combinations; to add to the space savings, rather than having a carousel or belt of tools, now you can have a pallet of tools off to the side, where the spindle becomes a pick and place machine during tool changes, which also simplifies auxiliary functions, and cuts out an auxiliary mechanism, which would cut down on the machine's footprint. Now for the cost savings, you would only need the 3 tool holders, not 75 tool holders. And maintenance time savings too, if you need to swap out a specific tool for a replacement, say from damage to the tool, you only have to swap the specific tool itself, not release it from the tool holder and set the new tool in the same tool holder. It makes logical sense for the industry as a whole to find a way to move in this direction. You save a lot on tooling costs, my example of going from 75 tool holders to 3 is a 96% reduction in just tool holders, which adds up to a lot in savings. But you also save in space, which also costs money, and can impact revenue; a space that used to have the occupancy for two machines plus the current carousel/belt tool changers could potentially now occupy three machines with the more space-efficient tool change design, this 50% increase of machines is also very scalable from small shops to companies that occupy entire warehouses. Of course I'm pulling these numbers out of nowhere, as the entire concept is hypothetical, but it is still based in logic. In the money making scheme, lower costs and better space-efficiency is part of the long term goal, as in the end it will be cheaper and generate higher revenue, along with the perk of better investments.
Hi John, why did you not model the tabs? It seems a bit like guessing using tangential extension on thinning the tabs. What did you use to limit 3d adaptive to not machine the place where you want the tabs?
You definetly should try a slithing saw instead of messing with the taps! I use that technique almost everyday you just create a sketch with 3 Lines: Partlenght then move over the thickness you are willing too leave then partlenght back. Just be sure to make the last cut on the right Side so it doesnt tip onto your tool. Greets from Germany seriously try it out you will love it!
so if you have a 2 cm wide part that you're slitting off, would you take off 1.5 cm on the front side, and then remove another .4 on the other side, so that the part doesn't fall on the saw?
I thought machining mild steel was cut dry. The coolant introduces thermal stresses to the cutter that make it wear much faster. Or at least that's what my tool supplier educated me on, I buy helical end mills as well. We use coolant on gummy materials like SS, but mild steel machines beautifully when cut dry.
How much is price on campleat?? And how did you gett your software sett upp whit your machine did you download your has or?? A tuturial would be awesome how you got your virtual machin inter setting upp software and stuff!! #💯 💯
Well, he's not a machinist or trained as one--I constancy see lots of mistakes but he works past that until he gets it right and learns from those mistakes. It goes to show that hard work and persistence allows you to be successful. Also, having a "school" allows you to get machinery at up to 80% off retail.
It does but it works with the tool lenght diameter holder that you give it But if you use a bigger holder for instance without telling Fusion then the machine could crash
On 5 axis platter style machines. That platter can hit the spindle housing pretty easy when tilted up. Most cam software don’t detect those type of collisions because an accurate machine model has to be incorporated in the simulation.
@@inventorhsm4996Thats true, but there are people that do not care about the modelled holders and just use a different one. A lot of dudes where i work for instance
@@JTMarlin8 Job specific for sure. Doesn't look like they will see that part when the project is done, so why spend the time and money on a nice finish.
5th Axis make an angle plate fifthaxis.com/rl96a-90deg/ which they advertize as "Machine 5 sides of a part without a 5-axis machine". What do you think of that idea? Is it worth it for a Tormach / SYIL home garage setup?

The table color is so close to the floor I thought Johnny was on the floor, and just MASSIVE.
I came here to say that. My jaw hit the floor until he hit his hand on the treads
I thought that too for a bit.
my reaction was exactly the same
Just caught a phantom smell of cutting fluid. Build is looking awesome!
I thought i was the only one who gets that :))

why did you cut out around the narrow end before milling out the notch.
This is the first time that I have seen a "clear" coolant. How cool is that? I was also impressed with the amount of coolant flowing and the flushing action it had.
dude thank you for all of the great videos
Judgement Day begins when Johnny can run the CNC machines :)
You guys should a full size CNC aluminum terminator T-800 - would be insane.
Once Johnny 5 is alive, he can make the rest of his crew. Are you going to call him Jonny 5-Axis? ;-D
John what kind of coolant are you using ?
Johnny 5 is getting a Damascus sword!

John, can you do a video, if it’s not already in the works, on the TruePath? Is it only for collision avoidance? How about 4th axis projects?

@@47EZ_DRIVER exactly you got it. I'd leave 0.3 mm for starters
Are you not running G187 P1 on your roughing paths? Cuts down a huge amount of cycle time.
Its very hard to machining when we clamp 25% clamp..75% in air...how did u made???is there no vibration and noise???
Can't wait for the knive from Alec Steele to be attached to J-5!!

At this surface speed yes, it probably should have been run dry to keep thermal shock at bay.
That looks great was Johnny 5 built using steel parts or aluminum.

Great work as always. Am sure this has been asked before, why fusion 360 over solidworks?

Someday he will realise how awesome lathes are too. :-) lol
@@bcbloc02 I am personally like him - 99.9% mill guy. Who knows, maybe one day.
how you code it? You have to write the G code? or it work with some type of CAM?
Fusion 360
What material is that??
You should break the scale on both sides before machining scale can bend and twist the part too if you machine one side first

Nice video gut this pice not strongly need a 5 axis machine.
