Machinist’s Mate

Filed under: Wimminz — wimminz @ 12:38 pm

I won’t bother with a link here, you can google it if interested, but the staple of the machine shop is the end mill, it comes in a variety of sizes and lengths and profiles and flute numbers.

Thing is for any given specific end mill, and any given specific material, there is an ideal chip load per flute per revolution, eg amount of material removed per flute per revolution.

If you want to remove material faster you pretty much need more spindle RPM for the end mill, which means more spindle HP, but even here there are upper limits, because of the material.

If you still want to remove material faster you have to go up in diameter or go to something completely different like a hogger wih inserts, but even here you still have effective ideal chip loads per pass.

That done, at its simplest you *can* use just the one end mill, and you do the job in two processes, you have your “roughing” passes which is removing the bulk of the unwanted material by volume, and then your finishing passes, when minimal volume of material is removed, you are going for the finer details and quality of finish.

It’s a machinist’s saying that the customer pays you for the finish cut, but the roughing (that no customer ever sees) is where you make your money.

All well and good, you have your CNC machine, you have your CAD design, how do you bridge the gap? Enter your CAM package, which basically computes the ideal toolpath based on material to be removed, end mill sizes, chip load, spindle rpm and a host of other things.

It’s that “ideal toolpath” thing that will get you, for my home hobby diy CNC converted metal milling machine I use Mach3 to run it as a CNC machine and a 300 buck CAM package to generate the toolpaths.

While my 300 buck CAM package is inordinately better than any free/ shareware / 50 buck package, it’s still basically total crap.

30-50k of CAM software will get you something that ensures that the machine spends most of it’s time with the spindle running at 100% power, which means most of the time with the same sorts of loadings on the end mill, which means most of the time with the same chip loads and material removal rates.

These differences between the low end shit and the high end shit are fucking *vast*, at the low end the toolpath looks like is was generated by a tetris robot, at the high end it is all sexy organic never ending curves that follow the same sorts of rules are railway track, eg curves should be fast and open, not short with low speeds and large deceleration and acceleration in and out.

It’s a thing that sounds easy to optimise, sounds easy to program for, sounds like it can’t make that much difference in the great scheme of things, but once you actually see it in the flesh you’ll spend about two weeks constantly going “wow” and re-evaluating the vastness of the gap between the high end pro stuff and everything else.

I suspect that “production rates” on my little hobby vertical mill could easily be made 500% better just by using better toolpaths generated by pro CAM software, of course this does not matter to me for my hobby use, but it matters to everyone else.

A modern production machine tool is a “thing” and that “thing” is composed of the hardware itself, and all the software that drives it, in much the same way that the modern vehicle is only a modern vehicle *with* all the ECU’s sensors actuators canbus and everything else… without them it is just scrap that won’t even start.

Going back to the machinist’s saying, if the roughing is where you make your money, then the toolpath is where you make your money, so this shit is the difference between staying in business and going to the wall.

The point here is that when you are in the game for real for for money, the metrics you use to measure shit are not what outsiders would assume, so machine shops will look at materials removal rates and kilowatts of electrical power used to do same, welders will use kilos of weld deposited over time and kilowatts of electrical power used to do the same.

You can get some very counter-intuitive answers this way, let’s say you have a car body painting line, if the newly painted part takes 30 minutes to dry instead of 2 hours to dry, then maybe you do not care that achieving this requires an entirely different kind of paint and application process, because at a given production line speed you just cut the size of the paint plant by a factor of 4.

There are of course “industries” where the opposite applies.

For my sins I am currently having to deal with commercial lawyers, and like bankers and teachers and everything else, they work another way.

If a landlord has 20 identical commercial units on an estate, and if there are 20 landlords in the same boat, then there are 400 pretty similar units up for rent, the lease agreement for one is going to be largely identical to the other 399, but to a commercial lawyer each one is billed as though it was a custom one off item, the same goes for bankers handling financial transactions and teachers doing class 3a’s 14th geography lesson of the year.

It’s the same old recycled shit with a few minor details edited or crossed out, and the reality is it is some junior clerk who will be doing 99% of the editing, but you get billed like Leonardo wrote the whole thing fresh by hand on vellum, and it kind of has to be like that, because if the even once do it properly and bill you 50 quid and take an hour, the whole game is up.

This same reason is why you will see industrial units and shops and even homes empty and to let or for sale, nobody drops the prices because then you would have to re-evaluate everything else in the row of units / shops / houses.

There are 147 numbered houses in my street, if they are all worth 200k then the whole street is worth 29.4 million, if the empty and repo’d by the bank one is allowed to be sold for 50k then you just wiped 22 million off the value of the whole street.

If the 1 million shares in the company are worth 100 bucks each then the company is worth 100 million, but if they start selling at a buck a pop then the company just had 99 million or 99% of its “value” wiped off.

Last night bitcoin was up to 19k, that was hours ago, so I haven’t even looked, so it could be 25k now or it could be 5k, who knows, it depends on how many are trying to buy and what they are willing to pay, and how many are willing to sell and what their minimum price is.

But again high end high speed algos make everything everyone else does look like home hobby amateur night.

To flip back to the CNC milling machine for a moment, your options are either changing the physical properties of the material, which is a non starter, or changing the physical properties of the cutting tools, which is a non starter, or getting even better toolpaths which at this point is incremental at best, or cutting the cost of electricity to run them, which is significant but there is also the capital cost of the equipment and tooling, which is huge, and maintenance and service and calibration, which is not insignificant.

In short, when you are dealing with real world physical shit, things don’t change that much that fast, because so many things are dependent on physical properties of materials, which do not change.

The new supersonic planes being mooted aren’t going to be very different from concorde, they are trying to do the same thing in the same medium so they are going to face the same challenges.

Less tangible stuff, not so much.

Two identical milling machine centres in two countries, you can drive from one to the other in 1 hour, on day one they are exactly equal, because country A works in dollars and country B works in roubles and the exchange rate is 1:1

Nothing else changes, but over night the exchange rate changes, 1 dollar is now worth 10 roubles.

If you like next door to the machine shop, nothing has changed, at first…. then you realise that 1 hour away the same shit is either 10x or 0.1x the price, all other things being equal.

At this point it is vital to remember that as far as the machinery goes, nothing has changed, it still takes the same amount of power and time to remove the same amount of material to make the same thing.

What has changed is everything *outside* the machine shop, it’s almost like one shop their toolpaths got 10x slower and so on, at least as far as competing commercially with the other shop.

It’s a “Game Over Man” moment, due to immutable physical law there is no way the higher exchange rate economy shop can compete with the lower exchange rate shop, it can’t be done.

Of course the reality is things are not so simple, our competition is now 1 hour away down a road with no transport costs and no border controls, exchange rates haven’t changes by a factor of ten at a stroke, and the rate at which lawyers / bankers / teachers etc recycle that same old shit and charge anew for it every time has only increased slowly and gradually.

But, anything and everything anchored in the physical world with physical laws has an analogue to aircraft stall speed, at X knots you are flying, at X-1 knots you are falling out of the sky, and the transition is immediate.

If you stall it, only two things will save you, a lot of luck, which in the real physical world means lots of overhead baked in, pilot skill, air-frame and engine over engineering etc, and lots of altitude, which in the real physical world means lots of essential assets.

Assets in this case does not mean accounting assets that appear on a balance sheet, 40 billion in assets on the airline balance sheet is no use to the plane 1 knot below stall speed, lots of altitude and lots of “luck” are the only ones that count.

Similarly, and importantly, 40 billion on the red doesn’t change anything either, at least not until the plane lands, then it won’t take off again…

Here at the tail end of 2017 we live in a world where 99% of people are basically unaware that such things as physical laws even exist.

Trump recognises Jerusalem as the crapital of Israel, well, seems to me any sovereign nation is the only body that decides where the capital is, if the UK wants to move the capital from London to say Bristol, it’s got fuck all to do with Trump.

If Trump / USA decided to leave their embassy in London, or move it to Hull, it doesn’t really affect anything, or does it, does it actually matter?

Does foreign approval and consent make a difference, because if it does it puts a whole new light on the russiagate bullshit.

But it doesn’t make any *physical* changes, Tel Aviv will still be where Tel Aviv is, Jerusalem ain’t moving, and nor is any of the history associated with the region.

Israel / Lebanon / Palestine, you can give it any name you like, it’s still the same geography with fuck all natural resources, the only way you can sustain the modern populations there is artificially, and we are right back to the physical world and physical laws all over again.

Move the goalposts in the non physical monetary / political world and you are like the machine shop that is suddenly 10x more expensive than their neighbour an hour away, it’s game over.

Apart from some software and cpu design and weapons, Israel doesn’t make anything, and what it does make is not unique, it’s like the machine shop, it’s very existence and survival depends on physical laws, and the ability to purchase raw materials and a Hass machining centre etc, and the neighbour down the road being 10x more expensive.

It has long been known here in the west that the Jewish nation is two countries, there is Israel, and there is the ex pat management and PR team firmly installed over in the USA running everything, and making sure Israel is artificially supported.

Nobody actually gives a crap if the capital of Israel is in Tel Aviv or Jerusalem or New York, for practical purposes for 99.9% of things it does not make a blind bit of difference.

It’s not about where the Israeli capital is located.

Jerusalem however is where three religions meet, and so for basically the past thousand years it’s been like a day care centre where mummy and daddy who hate each other and have multiple restraining orders against each other meet to hand over the kids every other Friday and Sunday.

It would have been a mistake to let either daddy or mummy buy it, but a far greater mistake to let an alliance of social workers, lawyers, courts and paedos buy it, and a far greater mistake still to let a bunch of human infant sacrifice types buy it.

The latter is what has effectively happened, perhaps in hubris, perhaps in a get in while we can before everything collapses so we can point back at this and call it legit, perhaps something else entirely, but the Jew managed USA and the state of Israel have finally crossed the Rubicon.

If you know that bit of history you know there is no going back, it’s too late, you’re in the same place as those machine shops, physical laws constrain your ability to adapt and survive and still stay in business, once you file for bankruptcy there is no going back.

EVERYONE involved in that company is now forced to make a new choice about their future, given the choices available, because the option to carry on as before has been taken off the table, and it ain’t coming back.

This is the reality of the situation with the USA / Israel / Jerusalem, it might not seem like it has anything to do with a machine shop or how lawyers and bankers and teachers work, but that is only because you aren’t looking closely enough.

Too many other parties will now be forced to make choices that they were not forced to make before, and they will also all be crossing the Rubicon sorts of choices.

But please, don’t pay any attention to any of that, look over there, shiny, norks, bitcoin, kardashians.

  1. It’s check mate, but for the palis, they officially lost, it’s best for everyone to admit that, like it or not, and talk terms of surrender.

    To quote Rush Limbaughs (American radio host) undeniable truth of life:

    “The world is governed by the aggressive use of force and the purpose of war is, and the purpose of armies, is to kill people and break things, that’s how you win! That may offend people, it may scare you, you might even think that it’s nutty and crazy. You are dangerously wrong if you believe that. I don’t care whether you like it or not, whether you want it to be true or not, or you wish it weren’t true. It is true. It has always been true, and it always will be true. It is because of the essence of human nature. Ours is a world governed by the aggressive use of force and we see it every day. The aggressor always sets the rules in any conflict. It’s not just the use of force that governs the world, it’s the aggressive use of force.”

    The great irony is that the pali defeat will be even greater if there’s a backlash! Israel is now in a win win situation if they play it right.

    • I’m going to respectfully disagree.

      To my mind it means that Israel’s only possible future is wars of expansion and conquest and resource seizure, and I do not think they or anyone else is good enough to pull that one off, win the hand and have everyone else walk away from the table in defeat.

      Israel just crossed the Rubicon, now everyone else is forced into making similarly non undo-able choice, not choices they wanted to take.

        You talk like I’m an honorable guest…

        I just don’t think anybody cares about palis anymore, not enough to walk the walk.
        I also believe that all status quo is based on force, and the palis have non to project.

        The Rubicon was crossed in 1948, and if not then, then certainly 1962 in Dimona.

        Look at the map, there is no Palestine proper, only unconnected patches of territory remain:

        Project this trend two-three decades into the future and it’s game over for them, the green will be a mere myth in 100 years.

        • “I just don’t think anybody cares about palis anymore, not enough to walk the walk.”

          There are a lot of people who care, but they’re not given any spotlight in the western media. Israel cannot ethnically cleanse the area, nor even support itself without outside funding and massive military support. Looking at a map of Israel in a vacuum may make it appear otherwise, but it doesn’t give context the geopolitical realities which made its existence possible in the first place.
