What I love about CNC
Is the same thing that I love about computers in general. I can program
a computer to do something that I want, automatically, and to run unattended. With this CNC mill, too, I do not even care too much how long a job would take. I just program it, double check that all the rapids are in the areas that are milled out, start the job and walk away to do something else. I somewhat watch the progress through a netcam, with one eye. This is just so awesome, to have a mill do my job, precisely the same way every time. i |

I'm only supplying the gcode?" He told me to "just watch", and we started the run. OF COURSE, it cut the sheet just the way I had optimized the toolpaths, and he was ****ed. He accused me of delicately designing the whole sheet in that cut order... GGG I used the same inexpensive CAM software (CAMBAM), that I use for my WAL- E (R2E4).

This is just so awesome, to have a mill do my job, precisely the same way every time. i One of the guys I got a machine from could sit back in a lazy boy chair with a wireless keyboard and program looking at a projection screen and the machine would start up in the garage. I wish I had the training, that would be cool. plus with CNC you don't have to locate each cut, that would be perfect for making duplicate parts. Someday I need to pay someone to make me some chess board pieces that are blank and generic so that I can customize them with manual machines. That way all the pawns and other matching pieces would be at least from the same stock size. Probably still cost a mint for the programming, stock, shipping, and a big hour on the CNC lathe. SW |

And as the computers get smarter, the cutoff IQ gets higher and higher, displacing more and more people. I'm not that concerned. I'm in a highly "manual" business. But besides that, let's take those slot boxes as an example. It took about 40 minutes per sheet to do the cutting -- more accurately, and better in terms of fit and finish than a human operator could have without spending 10 or 15 hours to do it. So, there's (say) 9 hours of lost labor for one _highly_skilled_ cabinet maker. BUT... it then takes about four hours of really good quality work to properly assemble one, and I can make more of them. That doesn't cheating the worker, that just increases his productivity. He can make roughly three boxes in the time it took to make one in the past. Bad? Saying the worker count is now down to one in three? No. I get to sell more. I couldn't afford to make more of them the old way. No budget for space, no budget for additional OSHA crap... I just would employ one worker, and make one every day and a half. If I make three a day, I'm still employing exactly as many people as I would have before. No net loss of labor. LLoyd |

: How do you like the ShopSabre? It does decent work.(+) Its base price is fairly low.(+) It looks "shop built".(-) After you add the necessary accessories, like the recommended (no, really necessary) Italian router head, and the 20HP ring compressor vacuum system, you're up around $22K, before you start to acquire things like phase converters, if you don't have 3-phase power.(-) I am not sure I'd buy one new (guess I would, if I needed it), but I would certainly own one that had been cared for properly at (say) half the new price.

I am very bothered by this and am worried what kind of society my kids will live in. Of course, I want them to be in the better part of society, but in any case I am worried and who knows how they will turn out. Also, I do not think that it is only a future issue: I think that the increasing disparity in pay, and stagnating salaries of low income employees, are due to the above described process of people being displaced by computers. i i i |

This issue has been the subject of study and speculation for a long time in the field of labor economics. Until the late '70s, it was assumed by many that work weeks would keep getting shorter while incomes grew -- the result of improving automation and its consequence, which was lower production costs. That was a time when the US was headed toward social democracy. Gunnar Myrdal's _Beyond the Welfare State_ (1960 or so) was sort of the guidebook for social democratic thinking. Alas, work weeks stayed the same. Part of the problem is that we grew out of our houses trying to store all of the crap that we made and bought. d8-) But the big issue was that we were never inclined to control the disposition of capital. Now, with globalization, it would be impossible to do so. -- Ed Huntress |

In the past, they could always have a job, like answering a phone or working on a conveyor or whatever. And now a computer could do all that work. That alone could be worked out, maybe we can somehow keep such people afloat in one way or another. But what about 20 years later, when computers could displace workers with IQ under 90? 95? etc? .... I think your model of a gradually-rising lower threshold on IQ will prove incorrect in the long run. Much manual labor is mechanically complex and expensive to automate. From a business point of view, computers can be more profitably aimed at the many medium-pay, medium-IQ jobs, rather than the many low-paying, low-IQ jobs or the few high-paying, high-IQ jobs. In any case, as computer memory and cpu cycles drop in cost, more and more office jobs will be at risk. -- jiw |

No budget for space, no budget for additional OSHA crap... I just would employ one worker, and make one every day and a half. If I make three a day, I'm still employing exactly as many people as I would have before. No net loss of labor. Only in the bogus case that there is infinite demand for cabinets. The net loss of labor doesn't happen to be at your shop, unless your competition gets a better robot than yours and underbids you for the undoubtedly finite number of cabinets needed in your area. Then you need to get a better robot than they have, or kiss business goodbye. Eventually somebody ends up with as much cabinet robot as the market will bear, and everybody else is out of business. -- Cats, coffee, chocolate...vices to live by |

Frequently where the unions are you find that there were no problems with the employer, but rather low skilled workers who were gullible enough to be scammed by union recruiters into joining the union and paying union dues while not seeing any actual benefit. I recall seeing some reports where workers are some large foreign owned auto plants in the US were cheering after once again defeating attempts by a corrupt union to impose themselves on the workers. Unions hate these non union competitors and will do anything and everything they can to cause trouble at such plants, since these plants are proof that unions do not benefit the workers. |

It tells me a lot about the employer It tells more about the corrupt unions than anything else. Some unions may be corrupt but many employers are corrupt or incompetent Unions exist where employees are treated like chattel If a business can't get along with its workers and goes out of business as a result that is just one consequence of free market economics Frequently where the unions are you find that there were no problems with the employer, but rather low skilled workers who were gullible enough to be scammed by union recruiters into joining the union and paying union dues while not seeing any actual benefit. employees don't vote for unions where there is already good communication The japanese automakers have numerous plants in the US and those assembly plants aren't unionized No unions because the employees think unions are not needed to communicate Toyota has in profitable years paid their assembly plant workers better than Detroit UAW workers And Toyota workers would join a union in a heart-beat if Toyota treated there employees like GM has Unions are a waste of productivity but they are a necessary evil when you have bad management I recall seeing some reports where workers are some large foreign owned auto plants in the US were cheering after once again defeating attempts by a corrupt union to impose themselves on the workers. Nah your not even close. Unions don't impose themselves on anybody Employees can choose by democratic elections to have an agent represent them. Do you think movie stars have agents forced upon them? If the union exist it is because the majority wants it to Unions hate these non union competitors and will do anything and everything they can to cause trouble at such plants, since these plants are proof that unions do not benefit the workers. These plants are evidence of good management They are evidence of good lines of communication between employee and employer those plants have gained market share because they are more productive And team work is the biggest part of that Nobody likes working for incompetent management |

That was great, but it was still REALLY tedious to cut out a dozen slots manually. if I went past the dimension a little in one place, it would leave a big gouge and I had to start over. Now, with CNC, I don't spend hours slaving over one panel and worrying that one little slipup will ruin the part. I don't run my machine unattended, but then the pieces I work on typically don't take very long to make, generally just 3-5 minutes per part. Most of the time is preparation, setup and cleanup. Jon |

I do think that the computer revolution is different from the past manufacturing revolutions, in the sense that smart enough computers simply do not leave room for any work for people with IQ below, say, 90. And as the computers get smarter, the cutoff IQ gets higher and higher, displacing more and more people. I'm not that concerned. I'm in a highly "manual" business. But besides that, let's take those slot boxes as an example. It took about 40 minutes per sheet to do the cutting -- more accurately, and better in terms of fit and finish than a human operator could have without spending 10 or 15 hours to do it. So, there's (say) 9 hours of lost labor for one _highly_skilled_ cabinet maker. Right. BUT... it then takes about four hours of really good quality work to properly assemble one, and I can make more of them. That doesn't cheating the worker, that just increases his productivity. He can make roughly three boxes in the time it took to make one in the past. Bad? Saying the worker count is now down to one in three? No. I get to sell more. I couldn't afford to make more of them the old way. No budget for space, no budget for additional OSHA crap... I just would employ one worker, and make one every day and a half. If I make three a day, I'm still employing exactly as many people as I would have before. No net loss of labor. Lloyd, but in a real high production factory (not one offs), they could have robots doing the assembly and packing, no people required. Depends on the costs. A mate went out to see a Denso plant in what was Eastern Europe and they had people assembling parts not robots, the reason being the workers were cheaper than robots. The parts were engine fuel injection system components. And if software evolves, the same factories could do one offs from CAD files or some such. Mass production of one offs, so to speak. i |
