    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.

    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!

      So what are the tools used, and the real feeds and speeds?

    • @JonProce
      @JonProce  10 лет назад +6

      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".

  • @joepie221
    @joepie221 6 лет назад +5

    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.

    • @hansdietrich83

    @MWolverine1969 8 лет назад +4

    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!

    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.

  • @horseshoe_nc
    @horseshoe_nc 11 лет назад

    Nice part. Little tip, the drill bird nesting can be stopped by increasing the feed rate or lowering the spindle speed. Both create a heavier chip which tends to break shorter.
    And on the high speed pocketing. Seems like that would put a lot of excess stress on the ball nuts?

    Jon I cast and it costs me about $1500 to set up and I can get just as good accuracy. Casting equipment is cheaper than milling. Milling is the conduit from CAD to casting. You can cast items in a single piece that can't be milled etc. have a look at it. Its worth investigating.

    Crazy number of steps had to be done correctly. All the manual repositioning, and getting the Code correct and matching... impressive..
    What is the principle behind the probe? Is it made using some strain gauges - like a load cell, Or is it wired to close a circuit on contact?
    I assume the ball radius and flexibility are selected to close the circuit at the center of the spindle?
    I'm trying to experiment with DIY probing. Made a strain gauge probe - it is too sensitive to work anywhere near to the stepper motors. Magnetic fields are too strong...

    • @FluffMuncher
      @FluffMuncher 9 лет назад +1

      Nick Bultman Depends on the price point. Billet aluminium is stronger than cast due to the way its forged. So you can buy Billet CNC footpegs and you can buy cast ones, price difference is like $250 a set vs $100 a set, roughly.. But if you look up people who have done home foundry work on youtube and look at the quality of it once milled vs the quality of these and the difference is night and day.I didn't understand this until I started milling and when you cut something like 6071 or 7075 vs cutting up a cast piece, it literally falls off like butter..

      i have done a new piece at work ...its not as many angles as this,but its done in one process ,but im gonna upload it in the future n u will c some cool things,,for the first its Stainless steel *not the trickiest materials in the wide range of Stainless steels its the 2302 ,i dunno the materialnumber in usa*for the secondly ..lol...someone miscalculated the length of the materials (me) so i almost didnt manage to set it up cause of the shorth length to grasp the piece on..sorry for my bad gramma n Spelling..but i cant upload before hearing with my boss so i dont do a blunder in anyway..u know what i mean:)

      And btw i know it sounded pretty cocky of me n it wasnt my meaning i can c that this piece took some serious time n effort to do...my gramma aint the best...i was trying to say that with my mazak dialog programming i can do some amasing Shapes with Little effort put in to it:)but the dialog is restricted to only 3 axles working at the same time,but with cam i can have 5 axles working at the same time:)
