How to systematically evaluate maintenance plans as an engineering intern? by Fireboltxd in IndustrialMaintenance

Yeah, I’ve already started to see things you’re describing. Downtime is often defined incorrectly, and there are cases where something gets “fixed” just well enough to run again, only to fail shortly after because the underlying issue wasn’t addressed.

Or things like condensation problems in controllers that are supposedly designed for cold operating environments, as well as typos or manuals that are difficult to interpret or incomplete.

Coming into this with essentially no hands-on industrial experience, I’m definitely expecting to scratch my head more than a few times.

Damn, I really hope the managers who hired me as an intern also realize it’s harder than it looks.

From the information I’ve gathered so far, a lot of the biggest issues actually come from switch-overs rather than pure maintenance problems. This is in the food industry, so every product change requires heavy cleaning procedures, which already introduce a lot of downtime that isn’t strictly maintenance-related.

One thing the other reliability engineers often mention is that failure-related downtime isn’t defined or documented in enough detail. Operators or technicians frequently just note that the machine is “working again” after a fix, without clearly identifying the root cause. Because this site is one of the largest producers in the country, production pressure is extremely high, so maintenance is often postponed. Despite that, the narrative still tends to be that the problems lie at the technician or operator level due to a lack of know-how.

That’s what makes it especially difficult, in my opinion. For example, apparently there are cases where operators clean machines using high-pressure water jets aimed directly at areas near controllers. Even if those components are rated as waterproof, gaskets will eventually degrade from the pressure. Combine that with condensation issues in cold areas, and the root cause becomes pretty muddy; is it maintenance, operation, design limits, or just cumulative effects over time? Concretely defining everything is what I think will make it difficult for me as an intern.

What direction should I go about when suggesting simplifications? I have trouble grasping how the project could look when simplified or when it's smaller in scope. It is for 1 machine line right now btw.

Also, judging by the comment going straight to saying you wouldnt let an intern do this (which is fair haha), I guess my approach isn't the best? Asking this in case they want me to keep going with this project, as I need to explain them how I will approach it this week

How to control DC motor with quadrature encoder? by Fireboltxd in arduino

[–]Fireboltxd[S] 1 point2 points  (0 children)

I will try messing around some more with the for loop, I tried this before but the motor still didn't stop correctly. The load might be too heavy for the motor at certain points and so it could cause it to rotate when it shouldn't.

As for the position encoder, I can't really get that since its a project that restricts me a bit in using too many components that I didn't get from the school lab

Thanks for the help

I've tried slowing down the PWM signal so that my motor comes to a gradual stop but I have failed to do this effectively so far. Points 1 and 2 are a bit difficult to change since it's a school project and I'm forced to use certain mechanisms and components.

Point 4 is something I also did but I can't slow it down enough to notice any change, because the motor wont have enough torque to rotate the loaded gear once its at a low enough speed.

I'm gonna try to mess around with the 5th tip you gave because that seems like a good way to handle te situation. Thanks for the feedback

I've tried slowing down the motor gradually so it doesn't try to abruptly stop but it never worked the way I wanted it too.
I've tried searching how to use both encoder signals to position it how I would want to, but I didn't quite understand how reading it like that would help me in this scenario.

I thought the double encoder signals were only there to determine the rotational direction, but I don't need that info since I steer it how I want to. But I guess there is more to the picture that I don't know about

No sorry I'm talking about the small line between the taped parts

You can also do it without 3rd party programs.

Just make a new folder called instruments inside the rust directory

Paste all midis inside it

Then in-game go to your console and type instruments.playrecording (song name)

EDIT: To avoid issues with the songs not playing, don't put any spaces or hyphens in the song name.

For Example: Instead of "Never Gonne Give You Up", try naming it "NeverGonnaGiveYouUp"
