I like the comment about "why not just buy one?" When you have your toys (CNC Mill) you want to play with it. It is not about being cheap or better, it is more about making it and having it on somebody's bike or such just adds a bit. As machinists sometimes we just gotta make something..even if it does not serve a purpose sometime. I love making things on my Tormach, despite the fact that I can buy it from an engineering supplies cheaper. But who cares, i made it!
The problem with people who say “just buy it” is that they don’t realise that the people who create the things that they buy are people like you!! Someone’s got to create stuff and use their skills.
That was beautiful! I just bought a four axis router, I'll never be able to do work like that with it but I can't wait to become skilled enough to make my own beautiful parts.
Wow this is really cool, I'm a 2nd year machinist running a fadal. I have a coworker who always talks up the haa's, cool too see one in action! Cool prototype!
Nice job. I've been programming for 35 years and I'll tell you one thing I have found; You give the same job and equipment to 10 different programmers and they will all come up with a slightly different program. (And according to them, theirs will be 'The Best')
Jon that is awesome I have never seen some thing like that I have always wondered when folks talk about CNC parts I had a understanding but I had never had an opportunity to see it happen Thanks and Thanks again ;O)
Looks great, the TM1 really is an awesomely capable machine for the money and since it can run on single phase power we could all run one in our own backyard shops. keep up the great work. Gerald
I am far from the consummate authority on CNC milling, but I have to comment. With all due respects. In your early operations, you spend a lot of time milling a deck around that square pin, then you mill away the majority of that deck in the very next op. I call that precision scrap. As for that hurricane cyclonic slot milling, not only does that beat the balls off the machine, you actually travel 4 times farther to finalize your slot. I've seen a lot of guys programming with fusion 360 use that technique. It may work in some circumstances, but I'm not a fan. I like the pegs. Nice job. I'll be curious to hear how long they stay horizontal as the aluminum sees repeated use.
Very nice work. The high speed toolpaths are sweet, looked like you were using trochoidal paths. I don't understand why people feel the need to bash on how you did something that they most likely couldn't do themselves. Keep up the good work brother!
Sometimes that's the case when you're prototyping a part. This was the second set I'd ever done, and there were lots of changes between this set and the first, and just as many since this was finished. Thanks for watching.
Hi. Right on both accounts. I've since substantially reduced the peck depth on the pre-drill, and reduced the feed and increased the stepover on the roughing to reduce servo loads. Thanks for watching!
looked great i am starting to go to school next month on how to use G Code for the Hass cnc milling machine. we started a class 2 months ago but stopped for the summer it only has 5 students in it and is being taught by a master cnc machinist programmer. future looks great!!
Hi. That is a Renishaw probe. It is linked to the machine via an electronic eye, and it will feed position information into the machine via macro programs. The first macro that you saw was it finding the exact center of stock stock, and feeding the coordinate into the machine as the G54 home location. Thanks for watching.
Very cool looking foot pegs! I'd be interested to see how long they last, they'd look awesome anodized! I would make one suggestion, you should kill the coolant and use an airblast for removing chips. The coatings that are on the tools are made so that when the tool is hot it activates, spaying it with coolant doesn't allow the coating to work properly and when a hot end mill or insert is sprayed with coolant, it causes micro fractures and will kill your tool life over time. I've been selling carbide tooling for a long time and I have few if any customers that mill any material with coolant. Here's tip If you run a tool too fast and it gets all galled up with aluminum, soak the tool overnight in toilet bowl cleaner, it will come out the next day as good as new ;) thanks for posting your work!
Hey everyone. Re: the seemingly high feed rates, keep in mind that parts of this video are sped up to keep you from succumbing to death via boredom. Re: other manufacturing methods like die casting etc., keep in mind this is a one-off part! This is the first and only set of these that have ever been (and maybe will ever be) made. CNC machining from billet is the only way to go for a prototype like this! Re: buying commercial pegs: these are MUCH bigger than a normal footpeg. They're designed to accommodate someone in a wide snow boot, not in a riding boot or shoe. Thanks for watching!
cncguru777 Spindle speed maxed at 4000 for most or all tools (surface speed still too low). The long tool is a Cormorant 390 (I think). Used a DOC of about 0.05" and a feed rate of 140ipm for all of the roughing stuff. Pretty standard rates for everything else. Chip load of 0.004" or so on the 1/2" tooling and 0.015" on the 1/4".
Very nice. The TM-1 is an amazing machine and the DT-1 can really get crazy with HSM. Everyone is an armchair programmer here, for sure. Of course most CAM posts can be tweaked to improve tool life or trim cycle time. But spending 20 minutes tweaking to trim 20 seconds of cycle isn't always worth it. All depends on if you are making 20 parts or 20,000.
I recently saw a lecturer at my university drive a Renishaw probe at full rapids through a 30mm thick HDPE workpiece. The probe was totalled, but it was quite amusing.
Looks like a great process. My only criticism is the high speed steel drills. But that's only if you're trying to make some quantity of them. If they're just for you it would be hard to justify carbide drills. Excellent work, thanks for posting.
Just a hobby. Learned mostly via trial and error, plus whatever I could find on the internet (which is almost nothing). Program & operate. Can't effectively do either without knowing a thing or two about the other.
This is very interesting, I'm starting mechanical engineering and I still don't know why they can't tech us how to operate cnc.. thanks for the upload.
Haha. It cracks me up to hear everyone screeming about the speed of feed. It's OBVIOUSLY been sped up. same kind of people that comment on lack of coolant in promo videos. It for display. You have to consider certain allowances. Good work btw. Quite a bit of work on a 3 axis. :)
Awesome!! Here in mexico, that service it`s too expensive and hard to find :( I see it´s made in a Home Depot! wooow, that kind of facilities are what make progress to a country. Congrats Jon!!!
