Override Door Interlock Doosan 2100A?

[gkoenig]

Why doesn't the Speedio have a door lock then?

The new D-00 machines have the same door locks as everyone else now. People have been a bit frustrated with it, and Brother is doing some updates in firmware to make it a bit less cumbersome. The days of just throwing the door open to stop the cycle are over though.

Just cut this section out? Thanks!

That's the part you "order" as a spare. That plastic oblong key does nothing for you.

Somebody find the post, was it Charlie Gary, who wrote up about what happened to him with a VMC with an unlocked door.

Yeah, leave it locked work around it.

LOL indeed
There is a reason for every rule and safety device, does not mean that every rule and safety device is the proportionate and proper answer, or even useful. It does mean that door interlocks are there for a reason.
Again, find Charlies thread
IF you are disabling door locks, you are a fool

I really dislike this mentality that if someone doesn't agree with your personal opinions on safety measures they must be a fool. It comes across as very condescending and pompous.

It's the foundation of many in this country today...That they are smarter, and know what's best for the idiot peasants. They force their will on others via laws, public shaming, etc.

We have lost too much in the name of safety, and I say it's overrated.....At this point it's been elevated to a ridiculous level.

Regardless of one mans personal story, you have to do something very dumb to get maimed. You point to this one incident with Charles as if it should be the sole metric when making decisions about safety. How many work hours does Charles have in front of a machine before this one incident? Does that matter? What mistake did he make? Does that matter?

People like you feel way too comfortable looking down at others and telling them how to live their lives. I suppose the internet makes it easier for you not to have to be held accountable for this poisonous attitude.

On top of that, why should anyone have to follow yours/others rules when it comes to their bodies? What happened to my body my choice?

And yet, this was my response to someone belittling my opinion on safety measures

But since you agree with them, they are not condescending or pompous

Funny how that works

I dislike that mentality myself

well that blows. That and touchscreens, what's the world coming to.

The issue is that once Government is involved, getting it un-involved is a lot more difficult.
When I worked for Doosan we had a customer get busted big time for loading tools into the machine's spindle by hand, even tho that was the only way to do it as there was no tool loading station. Why? Because someone at the factory put the wrong safety sticker on the front.

The horror stories abound with idiots doing S-T-U-P-I-D s**t and getting hurt or killed, only to have some tearful widow sue the big bad (read wealthy) machine tool builder and his "deadly" machines. At what point do you tell the crying wife and kiddies "sorry honey, but your mangled husband was a dumb ass and got what was coming."?

Either the grieving widow has to suffer and struggle or...what?

I've seen some really DUMB stuff, as I'm sure a lot of other folk have. Where does the responsibility fall? How many safety write ups does it take?

I hate door interlocks too. But I also hate getting in trouble with authorities who have near carte blanche power to shut your business.

Well, this did not work. The fine designers at Euchner were smart enough to not let some joker with a hacksaw (me) override the function with some modifications to the key. Don't bother, won't work. I'm going to have to dive a little deeper to get the machine to behave like a Speedio. Thanks for the input.

I got it working the way I want, but took a lot of digging. The Euchner sensor has 3 signals to the CNC, so non-trivial to bypass. I installed a different sensor that does not physically lock the door. I run the signals from an external PLC. Works just like the Speedio now, when the door opens, the spindle stops. I did install an override if I want to live dangerously for some reason, but I don't plan to use it much and defiantely not when any real work is being done. My first project besides the door sensor was installing a "backboard" on the catch tray. I was losing a lot of parts (would have to dig them out of the chips) because the catch tray can only get so close to the chuck. The flap kicks out a couple seconds after the tray is deployed, the closes back down with the tray retract. There's a pneumatic cylinder behind the foam, couple brackets and a hinge. Seems to work.

The metal key that goes into the switch has a part number. Order a "spare."

Or machine one

The problem with most of the safety stuff on current machines isn't that they are there, rather that they render the machine virtually impossible to set up properly.
Inability to turn on a spindle with door open eliminates the old fashion edgefinding.
Dialing in a tool for a blend is also out.
Touching up a chuck jaw on a lathe is out.
I can go on and on.

So, to help out in times when the need is there, one tends to either bypass, or permanently remove a safety device.
Would it not be better if the MTB-s designed their safety equipment that it does not need to be fucked with?
Have the safety device be fully protecting the operator - and the machine as it may - during normal, standard operation, but have the ability to bypass or ignore some of it during the
non standard times such as setup or repair of something.
I have 2 lathes from the mid 2000-s that I have never felt the need to bypass anything, even though they have them.
I have EDM-s that have only one switch disabled, but if you saw it you'd realize it didn't protect you from touching the EDM wire, it only protects you from touching the EDM wire IN THAT PARTICULAR PLACE!

On some others, I had to go to fucking town and more-less remove the safety device completely, even though there is a so called "setup-mode" that should eliminate that need.

there should be neglect variables in controls, at least there is on older machines
