Burrito Bozo

[Zoffen]

So Tuesday i get back from lunch, after a great big burrito, stomach full and brain on full carb overload.

Things are setup to keep moving along with the current project.

WCS was set before lunch but I want to check it just to make sure.

MDI.

"G55 X0. Y0."

I go to put the machine in 5% rapid but this BOZO hits the top part of the button....

and then also hits the "CW" spindle button with his fat ass fingers.

Probe proceeds to spool up to 12k with the door wide open probe a head level.

I freeze for 1 second just in shock and confusion what is going on.

Just as i reach for and hit the estop the probe stylus explodes and shoots into the side of the enclosure leaving a small mark in the lexan side window.

For 100 milliseconds i am pissed as hell at myself for beign an idiot yada yada yada....

Then I realize where the probe was and where it hit and 90 degs more and it might have been right into my face. Now i'm a happy camper to not have a ruby stuck in my head!

Soooo....

Next time you are just pressing buttons casually after lunch, remember not to be a Burrito Bozo and almost kill yourself.



And yes i do have S0 at the end of all my programs but it looks like I need to add another safety S0 at end of tool as well. Always a better idiot!

Thankfully Matsuura has a tool manager setting MAX rpm. 

You may want to add something to yiur tool change MACRO that sets S@60 or S@120 RPM when T= your probe number. 

You can't mitigate every scenario but you can get most of them.

Wow-sounds "exciting!"

I recall doing something similar just shortly after I got into CNC stuff....something like a boring head spooling up to 8K with a pretty good offset on the slide! I was at the machine and hit the big red button pronto, but yeah...."exciting!"

[Brian]

I've worked (mostly) alone for so long that I've kinda internalized a number of behaviors that are optimized for "survivability"....physically, mentally, socially, and financially.

It's not as bleak as it might first sound-it's just kinda an embodied humility that acknowledges human fallibility. Mistakes will be made, so just accept it....no shame, no blame, learn from your suboptimal outcomes-but I want the best outcome for myself and everyone around me as often as I can for as long as I can with the least effort I can muster! It's like "efficiency" that considers humanistic or social metrics, not just financial ones.

Yeah-glad that stylus didn't give you that frontal lobotomy you've been hankering for!

[Brian]

And yeah....the things that scare me the most are things in the shop that are pretty mundane: getting up on ladders (a now deceased friend nearly ended his career and life after a 2AM tumble), and the bandsaw. I like my opposable thumbs!

It's never the stuff that we're taught to be afraid of!

Did you Barf??

Or

Poop your pants??

Have you seen the video of the guy accidentally turning the spindle up to a ridiculous RPM with a flycutter in the spindle? 

[SuperHoneyBadger]

There's a shop legend around here about an operator who fat-fingered a facemill to S15000 instead of S1500. Those old ones where the edge of a big screwhead is all that holds an octagonal insert in the body.

A spool up, and then what sounded like a brief rainshower in the shop - followed by a string of expletives I'm sure. The guy is standing there, a hole in the window at forehead level offset just enough to miss him, and a facemill body in the now-stopped spindle with no inserts to be found. All the inserts except one had hit metal in the enclosure and were inside the machine, but nobody could find the last one... Until someone walks in after break and says, "hey guys, did anyone else see that VW with the busted window one parking lot over? It just shattered out of nowhere".

Car was parked 100 feet away from the shop, easy, and the insert found in the backseat after minimal investigation. And CSI style, they walk back to the building and find the hole through the metal siding and drywall. Those facemills are on the high-HIGH shelf now, de-inserted.

I'm guessing the door locks are removed/overridden to allow the spindle run to 12K rpm with the door open.

deceased friend nearly ended his career and life after a 2AM tumble

I worked with a guy who owned a small shop in Santa Ana back in the day (mid 80's)
He bought a new VMC that was delivered early one morning. The electrician no-showed
and the guy got pissed off and decided to wire it up himself.
He fell of a ladder and landed on his feet... on a couple of lengths of Ø1" bar stock.
The stock rolled, and his leg shattered.
There were no cell phones in those days and the landline was in the office. He crawled, passed out, came to
and crawled some more all night. He was about half way to the phone when the day shift showed up.
They couldn't get in because the doors were locked, but they saw is car in the parking lot, heard him screaming
and broke in.
He spent nearly a year in casts and his leg never did come back 100%. A decade later he was still having nightmares.

Back in the early 90's I saw a kid try to move a bunch of material using an engine hoist. He put too much weight on it and while he was trying to push it back, it tipped over and landed on is foot. He was wearing steel toed boots and it crushed the steel toe on one of the boots. He lost the entire end of that foot.

It was pretty messed up.

Burrito boys unite!

When my first Feeler arrived with its 15kRPM spindle that took a sillysecond to spool to flat out, I also had, a moment....

Edgefinder in the spindle and 15k caused it to explode and bounce around the inside of the enclosure.

In my defence....The spindle start (CW) button – all our other machines ran at the last commanded speed.

So MDI S1000 and then hit reset to stop the spindle – then press spindle start (CW) and it they ran at S1000.

This machine ignored any previous command, and spindle start ran straight up to max whether it was wanted.... or NOT!!!!

It, was only, a parameter change....

I have NEVER done ANYTHING that stupid, with a probe.

I did do something just as stupid with one of my $300 Interapid indicators.
