At 2:50 you mention high feed milling and how it produces much longer cycle times based on limited depth of cut. I wish you guys would address this point in greater detail. I’ve commented before about how it would be nice to go in depth about high feed milling vs hem and when to utilize either of these strategies, or possibly some guiding principles, and why. Also it is my understanding and experience that both hfm and hem can be very productive it is just dependent on numerous factors. So to say that hfm undoubtedly produces longer cycle times than hem is a bit of a generalization, no?

Wow @ 7:18 there is a non default holder. Finally!

Especially with multi axis toolpaths. You guys should make a video about setting up a machine sim. I'm trying to get an okuma mu 4000 setup in mcx 2024.... Nobody seems to really know how to add a new machine sim setup. Also... the endmill broke when the engagement increased on the other side of your fancy cone........ so your "solution" created it's own problem. Just pocket out a bore with straight walls. It will rip of way smaller tabs. A lot of people swear by solid holders but just like you said the screws came loose.

[@benjaminshropshire2900]

@@barrysetzer Well, you could turn everything _else_ and then mill the feet down from there. Actually, what I'm wondering is what it would take to set up a short run metal casting operation. Maybe CNC or 3D print a form for lost wax/foam casting? A quick search suggests you lose a few dollars a pound for anything that gets milled away. Add a few $k in mills and a week'ish of shop time and you could still be ahead paying a steep markup to get a casting. That said, you would be limited on the types of treatments you can offer so some jobs it just won't work with.

Why not just drill a hole to eliminate that last central tool-breaking tower, instead of that long slow spiral path?

[@zimbab5748]

Barrrryyyy!! You're the man. But brother did that new tool cut well. Some science to check out, temperature of material + work input from cutting(actual energy energy to cut metal/theoretical minimum energy to cut) = final work done = temp of chip + change in temp of material + tool tip temp. Therefore if final temp of chip is super high you are putting in way more energy to cut, in this case, friction. That why the rig stopped flexing as much when you did the tool change. Monitor the machine torque and axis/vector forces to tell when the cutting edge has dulled. Forces needed by the machine increase substantially. Round 2 🎉

[@dwaynesykes694]

But then KM wouldn't get to sell as many $1k endmills to guys "trying to put food on their table." Instead those endmills would get reconditioned for a fraction of the price and get re-used a number of times. Most (all?) nice machines have metrics on spindle load, servo load, and vibration that can be used to trigger a tool change. I know Siemens 840D can, at least on DMG machines.

[@zimbab5748]

@@dwaynesykes694 very cool! Can those carbide mills be reground? I would have thought that would be the norm these days with electronics, auto change based on load and vinration. I guess they are seeing just how many lbs they can get off without touching the tool. But makes you wonder if you had 5 endmills for the job, and used them until then needed a regrind but not killed them, would the job go faster and more efficiently? Because you were cutting at optimum for more of the time. But the machine puts it through at the same speed so guess you wouldnt notice a difference, machine energy consumption would have to weigh in.

[@dwaynesykes694]

@@zimbab5748 they absolutely get sent back to the manufacturer for reconditioning (their fancy term for. re-grinding) at most shops. Claiming that you can make more money by blowing up a $1k endmil, potentially a $1k toolholder, and sending a ~2lbs chunk of carbide flying through a million dollar machine is just reckless. Great way to make money if you make videos and sell tools for a living, horrible way to make money if you make parts for a living.

[@dwaynesykes694]

@@zimbab5748 for some perspective on how "smart" the advice in this video is, a comparable endmill from everybody's favorite Swedish tooling manufacturer -- whom I shall not name to avoid having yet another comment nuked -- is 862 US greenbacks new yet can be reconditioned by the manufacturer for a mere 72 bucks up to four times. Amortize the cost of the tool and four regrinds and you're at 230 per wear-cycle on the tool, which makes the cost of solid carbide a lot more palatable. Those numbers are also list, any shop running enough material to justify 1 inch solid carbide is likely to have an account and consequently lower numbers than that. Regrinds on anything less extravagant than a 1" wide x 4" cutting depth 7 flute monster are substantially cheaper, making it even more sensible to NOT break your tools. The ability to regrind, plus the fact that blowing up a tool almost always wrecks a a fancy hydraulic toolholder (or at least the collet if using one), and you can begin to see why no one else is out there telling you to intentionally break your endmills... except shameless shills.

Have you considered running a tank of crushed dry ice inline between your machine air supply & the tool?? The cold air & semi solid CO2 combo would be similar to running coolant with the CO2 possibly acting as lubricant.

[@clubdjmarcus]

That will just build up ice on and in the line, and it will be pure water, you don't want that in any part of your machine... Also dry ice evaporates to pure nitrogen, not something you want to blow in a room for 30 hours...

[@alt5494]

@@clubdjmarcus Dry ice is pure CO2 it does not contain notable amounts of nitrogen unlike the atmosphere. Compressed air also has very low water by volume. What is present will freeze inside the mixing tank before entering the lines. To raise CO2 from base 400 PPM to dangerous zone of 40,000 PPM. In such a massive room would require multiple tons of dry ice to be melted with all ventilation removed. Also liquid nitrogen is already being run in machine tools with no issues at even lower temperatures.

[@dwaynesykes694]

You absolutely should try to avoid breaking endmills. Running faster to trade tool life for lower cycle time is fine, but not to the point of failure. It's not just the endmill, it's the holder and potentially the machine that are at risk from breaking a tool, especially a large 1" solid carbide endmill. High end hydraulic toolholders aren't cheap, and you can pretty rapidly push a job well past the cost of a little extra cycle time when you start breaking things. And forget running lights out like this, no one wants to come in to find a crashed machine in the morning because a tool broke.

How do you calculate machine shop rates

You calculate how much money the mill costs you per hour, the purchase, the shop space, etc. Think about how much you want to pay back your machine, the profit you want to make and look at the rates other shops in the area will charge

[@bill4639]

First you add how long it takes to film per hour, then you add the cost of the cameras and film crew, then you add the cost of editing, then you add the cost of all the broken tools and bearing wear, then material cost. You get to subtract all the advertising money from the CNC machine companies, tool makers, and KZbin revenue though.

[@brodyhmachining]

Running a 1" endmill until it breaks is pretty inefficient. Inspect the tool, mastercam even has an option for this after time or inches in the cut. Saves you chasing where you were in the program and saves your holder, part and spindle.

[@Guds777]

Does Heller CP 6000 have a load sensor in the spindle. Like if it is doing a tool path and suddenly the load changes from x watts to much less watts it can sense that the endmill did break. Or were you just lightning fast on the emergency stop button...

Good controls have a mid file start option that checks the code for any g and m codes that might need to be set before returning to the cut (like tool length offsets or something)

For most materials in a cnc you'll almost always be climb cutting (with the cut). You get better tool life, surface finish, and chip evacuation.
