I’m an experienced CNC machinist and trust me, whatever you do, don’t machine like this! The program might look good but the parts will be dog shit when they go through inspection. Maybe if you’re working with +/-0.5mm tolerances but not if you’re making high spec components
@@bethfaulkner4907 obviously you're not he has a great machine he is producing a great finish what else would you want? that is the beauty of having a DMG
@@bethfaulkner4907 Idk about you but I was able to hold under 0.1mm on all critical dimensions of all production parts on a M1, by spending huge effort in correcting the runout of all tools upon installation and having done a reversal method calibration of the tool presetter (it is repeatable to under 3μm but it measures a little oversize out of the box and doesn't account for deflection either), and fine tuned my program after the first run. I was running only high quality and high end tools, to their peak performance limits, and just knew when to toss them, as I was full slotting on steel at 1.25xD, at up to 1.7meters a minute feed rate with an 8mm end mill, or side milling aluminum at up to 7.2meteres/min at 12k rpm with a 12mm end mill, or side slotting others at 15 freaking meters a minute with (and never skipping a beat, never missing a corner). The most impressive for me was drilling 9mm holes through 30mm of steel in under a second (a smidge over 0.78 seconds at 2.25meters a minute) with a solid carbide drill, and lasting for more than 3000 in size, on position, and pretty damn smooth and shiny holes (the end of life condition of this drill was wrapping 2 thick chips around it at 6k rpm and filling the whole factory with a mist of coolant, due to under 0.2mm of wear on it's split point)! As an experienced CNC machinist myself, I can say that It is way more repeatable than putting diapers on your machine, and while you will probably never be able to run prototypes and one offs like that, it's the only way to run for mass production!
@@gredangeo true that part would have been almost completly deburred in about 20-30 secs maximum in that time the operator can do something better than deburring
If this is still an active part. Everything looks great but there is a missed opportunity for part process security. Use the ball nose endmill that you do the rad with to deburr the part. This will add cycle time but the part will need considerably less hand work to be shippable or weldable.
I've never dealt with live tooling but I have to ask but not why not drill the hole after the endmill instead of before? This would likely decrease cycle time and improve insert longevity since there will be less material to cut through. I'm assuming is has to do something with how thin the material will be after the endmill? Looking forward to your reply.
Correct, its down to how much material is left after milling. The length, overhang and finish thickness all have an effect and caused the part to deflect when drilling, this creates a list of issues. Ideally all milling would be done and then drilling, but it isnt possible in this case
Just 1 tool being used to cut the OD in this process. 2 tools mounted on the same position with different Y offsets so what you are seeing is probably the other tool.
To me it looks fine. If you have a stable machine and the rigth inserts its no problem. And did you see any sparks? Or other things that did not look okey?
No offense but how on earth can any of you guys determine if this it good or bad feeds or speeds. You dont know what material this is, what kind of inserts are used or what the priority of this job is. Or am i missing something? And the thing about not using coolant. Any machinist that has not lived under a rock for the last 10 years know that dry machining is more and more common these days. Cutting fluids main job is to get burrs out of the way, provide cooling comes second. Buying and disposing of coolant is a big cost for companies and their staff/enviroment. A lot of people develop allergies and stuff from working with these chemicals year after year. Modern inserts can take the heat and actually lasts longer with a stable temperature, especially during the milling operations. I have seen so many shops running their machines and tools on half speed believing that they are saving money cause the inserts last longer when the real costs is salaries, machines, rent etc. At least here in Sweden the average cost of an quality insert is 10-12$ which is a small fee relative to other production costs.
Daniel, I totally agree with your first paragraph. The only thing I was wanting to change was all the extra axis moves during the tool changes and when the tool would retract so the spindle could rotate 180 or do another operation. So jerky and annoying.
May be drilling operations are better after milling operation and in this component too much stock removed for this component. 5 mm dia meter machining allowenc is sufficient for cnc machine and also tip life also became longer
@@kransurfing This. I would program the conveyor to run only for the last detail of a 5 minute program so it would let enough chips pile and then carry them up to drain. This cut down our coolant interventions to a quarter and we almost got rid of carry out, since the tank would hold an oil content of within our desired range for months, while we were just topping up with deionized water to compensate for evaporation, about every 4-6 shifts of high volume production
If you want to do production run with those parts I suggest to start with smaller stock. I like the agresivness of operations the machine was used but not abused
I guess that's for demo purposes, I was baffled by the confident depth of cut and no predrilling with a smaller diameter. Great machine, confident machinist/company :)
I think this is good, just some weird series of operations going on at points. Not much adaptive machining going on either, more brute force machining but hey, I guess we all have our ways

nice job
Thanks for taking the time to make the video and share it
Nice programming and the right cutting data! Presumably it is a high volume to detail because deburring did not occur :)
Well done!
Thank you. Yes, almost all batches in production are large quantity so most machining time is used to remove metal instead of deburring
@@PBMachineTechLtd I don't know why you wouldn't deburr in the machine, it's better and more reliable than getting an operator spending hours at it.

A hell of a lot of shavings. Surely in the end there will be a fierce overpricing. But the machine is, of course, awesome.
If this is still an active part. Everything looks great but there is a missed opportunity for part process security. Use the ball nose endmill that you do the rad with to deburr the part. This will add cycle time but the part will need considerably less hand work to be shippable or weldable.

Can i know the price of this cnc
well, how about expensive? will that do?
This machine is CNC or HMC
Please clarify the doubt expert's
This machine have a spindle axis so I assumed this this machine Horizontal maching center
This is s CNC Lathe, not machine centre
@@aravinthkumar6649 Its a lathe with dual spindles and a turret with live tools.
How are you not getting any vibrations??
Operations are in a certain order to reduce as much as possible
May be drilling operations are better after milling operation and in this component too much stock removed for this component. 5 mm dia meter machining allowenc is sufficient for cnc machine and also tip life also became longer
The stock is stiffer before milling to allow for higher drilling forces, don't you think?
Correct. Stock deflects if drilling is carried out after milling
A mori with gang tooling?
Try machining like that on a Doosan. No chance. DMG MORI machines are the absolute best.
They are hard to beat but my Haas mini is close 🤣
what does the SY stand for
Subspindle, Y axis
Where is the coolent??
Coolant on = nothing to see
Keep that conveyor off during most cycles. It's a good way to get chips down in the coolant tank
and mainly it lets the chips drain of coolant first you lose a lot of coolant if you leave conveyer running too often
@@kransurfing This. I would program the conveyor to run only for the last detail of a 5 minute program so it would let enough chips pile and then carry them up to drain.

Hole drilling can be done after milling to reduce CPC
I think it is being drilled this way because before milling you have a beafy chunk of metal so your part won't bend while drilling and boring.
Correct. Drilling was done like this because the part was deflecting if drilled after milling.
If you want to do production run with those parts I suggest to start with smaller stock. I like the agresivness of operations the machine was used but not abused
