Now I suspect this was becuase they were problem solving in a hurry as it needed to be ready to show off to the press. The guards and interlocks were no doubt not in place yet as that would clutter up the photoshoot. But part of me thinks there could have been some software safeties in place. The unit has image recognition and it's been taught to know boxes and products so why not go the extra bit and teach it humans and to avoid them. This would add extra complexity but at least it could help avoid an ED-209 moment. --- End quote --- For the same reason the floor managers in Black Phoenix's post were bypassing safeties to save 2-5 seconds per 1 minute operation. |

But probably it could have been done better. Though, safety has a cost, and if most companies using these tools favor productivity to safety, they're not going to buy more expensive tools just for added safety. Unless they absolutely have no choice. |

I wonder if they are doing their savings calculations correctly. You have to save a lot of minutes to pay for the downtime that occurs from an industrial accident. Even without the insurance and legal and other resulting costs. |

If not happens it's still time saved in a operation, who at the end of the year means X amount of production extra that otherwise would not be done that year. That is the mentality of all this safety equipment defeating purposes. For example the operation steps to open a door in a CNC lathe normally with the safety not defeated is: - Program should be finished; - Rotate key from run to maintenance mode; - Press button on the panel to open door (releases pin in the interlock); - Slide door to open; - Press pedal to open chunk jaws; - Take finished part and put new one; - Press pedal to close chunk jaws; - Slide door to close; - Rotate key from maintenance to run mode; - Press run bottom to start the program. Now with the safety defeated: - Slide door to open while program is almost finished; - Press pedal to open chunk jaws; - Take finished part and put new one; - Press pedal to close chunk jaws; - Slide door to close while at the same time pressing run bottom to start the program. You saved 5 to 8 sec per part. In a 1 minute program you have a free part each 10 parts you do, multiply that for thousands and you see how much more productive it is. But you are not wrong in the thought plus insurance companies would deny any compensation to the company and worker if safeties were defeated. Although safeties would be put in working condition after any accident as machine crashes and before the insurance claim and insurance personnel to arrive at the factory to assessment of the situation. |

yo that means their stupid if they need to switch out parts that much in serial production, like you need a bigger machine where multiple parts can be simultaneously fixtured. Like a parts holder with those fancy screws that tighten it from the bottom or something so you can put like a bunch of them in there. I expect the machine is being used at 5% capacity though because no one wants to figure out how to put more stuff in it. Like I am imagining a manufacturing cube with like a single small part in there. if someone has to do something every minute that does not involve a conveyor belt then its really suspicious. Like opening a door every minute. I am imagining like a 12 + inch kurt vise inside of a machine that has a interior of like 5x5 feet at least processing a single 2x2 inch basic angle piece, when you can put like 30 of em in there with the right fixture. |
