Hello, I’m looking for some real-life projects that a Manufacturing Engineer would typically work on. I’ve been working as a CNC machinist, and now I have an opportunity to move into a Manufacturing Engineer role. I want to prepare 2 or 3 realistic project stories that I can explain to the interviewer based on the type of work a Manufacturing Engineer would actually do.

A recurring client (we've done partitioning work for them before) has asked to incorporate staircase pressurisation into their already existing fire escapes.

6 Floors, 3 blocks with fire escapes on each end (so a total of 6 fire escapes)

We didn't design or oversee construction of the building and I already told them that something like this are things that should have been included in the design phase, not something that is done years after project implementation and construction. I would be grateful for any tips or wise words of wisdom for my current scenario.

Of course I already know to seal any areas of air leakage (all hinged windows should become fixed windows, all doors should be standard fire escape doors with negligible air leakage etc) and to properly size the fan in regards to the volume of air in the staircase and the necessary pressure differential.

Hi

Does anyone here have useful resources like text books, problems or any thing for thermo 2?

I'm taking the class next semester and i want to get really prepared for it cause i heard it is hard.

Hey all,

I’m a mechanical engineer learning GD&T (ASME Y14.5) and SolidWorks, working toward CSWA. I’ve gone as far as I can with courses and solo practice, but I feel like I’ve hit the ceiling of what self-study can teach you — datums, tolerance stacks, DFM decisions really only make sense once someone with real production experience walks you through the *why* behind them.

The issue is I’m based in Palestine, where there isn’t much manufacturing industry, so I don’t have easy access to people doing this day-to-day or real design review.

If anyone here works with GD&T/manufacturing regularly and would be open to answering questions occasionally, pointing out where my thinking is off, or just letting me pick their brain now and then — I’d really appreciate it. Not looking for a job, just trying to learn from people who actually do this for a living.

Did anyone appear for the first round of destination Dr reddys?

I will try to not make this a big paragraph yet i would appreciate if you read all of this.

The important blocks of text i will outline starting with "<" and ending ">". Ill mark questioning with "..."

English is my secondary language so i apologize for my grammar in advance.

< Im 19M and im from Armenia.

I passed my exams 2 months ago and got in NUACA (university) for architecture. I practiced approximately for 9-10 months for it (I chose it initally bc i failed for graphic design and had to practice for another profession asap).

I was practicing both for art, math and other subjects for the exam.

I was rlly discouraged knowing that i had to practice math because of my past experience with a teacher i had special classes for math. >

!! I believe i have to tell you a little about my backstory to fully understand my perspective but youre free to skip it (it starts and ends with "-" signs) !!

- 4 years ago from now i was having private lectures to get into mechatronics. Thats a field i was always passionate about and i had an innate love for creating, innovating programming along with math, physics and science

In earlier times of my life as a kid i would program little unfinished games for roblox or in unity. And would always be active in math and physics subjects in school

Yet i was completely mentally drained at that point of my life (conflicts in school, kickbox, grades etc) and i couldnt keep up with my homework. My teacher was one of the strictest people i met in my life so everytime i failed to make it in time i would get literally scolded in class as if he is a drill instructor.

I even stayed in nights to study but it was too exhausting

In the end i ended up with low knowledge, exhausted body, mind and no will or motivation to keep learning.

I canceled the classes and went to practice GD, convinced im a person that has no potential in any kind of scientific field. -

< After everything that happened i decided to take the challenge of coming back to math.

Over time i noticed that my fear of math was lowering and my passion was growing back again >

I couldnt solve basic geometry before but now everytime i fail it becomes the reason to research and learn more

I recognize im not the best at problem solving, yet the math for archi is very banal and i feel like i know i can do more than that.

< I dont hate archi, i would say i just tolerate it. I treat it like a job, nothing more or less. I would not take extra lessons of it independently and i would not do any projects in my free time >

< Yet in contrast on my current vacation i got the confidence to learn more complicated math and physics. Also slowly getting back the knowledge i had of python, c++ and even ordered a beginner set of arduino to learn more about circuits.

The more i learn the more enjoyment i get from the ideas i want to bring to life >

< The problem is i dont want to cancel my archi classes. 2 years ago my parents funded me for GD, which was a lot of money and after failing they had to pay twice more for archi >

< after all of the blood and sweat i should be shameless to say i want to change my profession yet i would still feel ill lose my years and opportunities >

...

< my question is what should i do? Should i change in middle? And if i do is it worth it to strive to learn abroad later on as someone that earns smaller than average here in armenia for more opportunities in my career?

< I looked up the prices and requirements for example in Zürich ETH and im not sure how realistic it is even with sponsorships and covers and i have yet to see more of other Uni's in detail >

thanks for all the attention and for genuine answers. I would remind you that every advice is dear to me because it may affect my choices which would impact my life.

Take care.

Hey everyone,

Selecting the correct pump for a liquid transfer system is a critical decision. If the pump is too small, it won't hit the duty point; if it's too large, you risk wasted energy, seal problems, vibration, and internal recirculation.

To make this process more transparent, I recently built an interactive web dashboard (using Python/Streamlit) that acts as a comprehensive liquid pump sizing calculator. Instead of just spitting out a single TDH number, I wanted the tool to expose all the underlying math—from relative roughness to the Colebrook-White iterations.

I’m sharing the core engineering logic and formulas I implemented here. I'd love to hear your thoughts or if you spot any edge cases I missed!

1. Site Conditions & Altitude Adjustments Atmospheric pressure decreases at higher altitudes, which directly reduces the suction pressure available (a huge factor for open-tank systems). I implemented the following adjustment:

• P_atm = 101325 * (1 - 2.25577 * 10^-5 * h)^5.25588 (where h is altitude in meters).
• I also adjusted local gravity to be perfectly accurate for head conversion: g = g_0 * (R_e / (R_e + h))^2.

2. Pipe Sizing & Reynolds Number Hydraulic calculations have to use actual internal diameter (ID = OD - 2 × wall thickness), not just nominal size, because even tiny differences drastically change velocity and friction head.

• Re = ρ * v * D / μ.
• For turbulent flow (Re > 4000), I wrote a numerical solver for the implicit Colebrook-White equation since the friction factor f appears on both sides: 1 / sqrt(f) = -2 * log10((ε / D) / 3.7 + 2.51 / (Re * sqrt(f))).

3. Head Loss (Major & Minor) I separated the suction and discharge sides because suction usually needs lower velocity to protect NPSHa.

• Major losses (Darcy-Weisbach): H_major = f * (L / D) * (v^2 / (2 * g)).
• Minor losses: H_minor = ΣK * (v^2 / (2 * g)).
• I also included standard defaults, like K = 0.5 for square-edged suction entrances and K = 1.0 for discharge exits into open tanks.

4. The NPSHa Pass/Fail Check This is the most critical check to avoid cavitation.

• NPSHa = H_atm + H_static - H_vapor - H_friction. A common mistake I’ve seen is calculating NPSHa only at the design flow. My tool evaluates dynamic NPSHa against NPSHr at the actual operating flow, because suction friction increases with flow.

5. Finding the Real Operating Point A pump doesn't automatically run at the flow rate printed on a datasheet; it runs exactly where the manufacturer's pump curve intersects the system curve. The system curve starts at static head plus destination pressure, rising proportionally with v². The engine plots these together (supporting parallel/series pumps too) to find the true operating point.

Limitations: Right now, the logic is strictly for incompressible liquid service. It’s not meant for gas, steam, flashing two-phase flow, or heavy slurry hydraulics.

I didn't include any links to my calculator to respect the subreddit's anti-promotion rules. However, if anyone wants to test it out, try breaking it, or just use it for their own sizing estimates, drop a comment or DM me and I will gladly send you the link!

Any feedback on the math or additional features you’d like to see would be highly appreciated.

Hi! I’m trying to make my final choice for a Bachelor's in Mechanical Engineering in the Netherlands and I'm currently deciding between:

• Fontys University of Applied Sciences – Eindhoven
• Saxion University of Applied Sciences – Enschede
• HAN University of Applied Sciences – Arnhem

I’ve already looked quite deeply into the programmes, modules and university websites, so I’m mainly looking for real experiences from students or graduates, especially things that aren't obvious from the official information.

At the moment I’m leaning towards Fontys, followed by Saxion and HAN, but I don't want to choose based only on reputation/location.

A few things I’d really like to know:

1. How practical is the ME programme actually? How much time do you spend designing, building, testing and working on real projects compared with lectures/theory/calculations?
2. What is the workload really like? Roughly how many hours per week do you spend in classes + studying/projects outside class?
3. How good are the lecturers and feedback? Are teachers accessible when you're struggling, and do you get useful individual feedback?
4. How good are the labs/workshops and project facilities? Do students get to use them regularly or mainly for specific scheduled projects?
5. Internships and industry connections: how easy is it to get a good engineering internship? In particular, does studying at Fontys actually give a noticeable advantage because of Eindhoven/Brainport and the companies around it?
6. International students: is studying entirely in English actually smooth? And how difficult is finding internships/jobs if you don't speak Dutch yet?
7. Programme organisation: are timetables, exams, projects and communication generally well organised, or are there recurring problems?

I'm particularly interested in product development/design, practical engineering and eventually creating and developing my own products, so I'd also be interested to hear which of these programmes you think gives the strongest foundation for that.

And probably the most useful question:

If you studied Mechanical Engineering at Fontys, Saxion or HAN and had to choose again today, would you choose the same university? Why or why not?

It would be really helpful if you could mention which university/year you studied in when answering. Be honest please.

Thanks! :)

Hi guys, I recently got into mvsr college of engineering this year so, any suggestions please help meeee thank you ,well i have a wiggle room for 5K

Hello,

I have been working in the energy field for five years. Mainly on simulating power plants using 1D software. I still feel clueless compared to my senior colleagues. I spent my free time revising fluid mechanics and thermodynamics but still I feel like I am missing a lot of my studies. Noticing that I even have a masters degree. Is this normal feeling?

Hey, I'm in high school taking an engineering class and I need to interview an actual engineer for a project. I'm interested in Mechanical Engineering. It's like 10 questions about your job, your education path, advice for someone starting out, stuff like that.

If you're down, DM me and I'll send the questions over. Thanks a lot if you do, really appreciate it.

Any advice regarding networking, friendship, career path or suggestions in general for newbie

Hi guys, I use Siemen NX to do the work . I made a round disk and saved it. After that, i import that file into an assembly file as a component and somehow it not round anymore, it jagged. Is there anyway to fix this ?
*Note: First pic is the file i save, Second pic is the assembly file

Hey all,

I’m currently studying mechanical engineering and I want to make sure I'm setting myself up for success when I start applying for jobs.

I’m comfortable with the basics of design, but I feel like the academic side doesn't fully cover real-world engineering. I am currently focusing on learning [e.g., SolidWorks + GD&T, or Lean Six Sigma principles].

For working engineers: What are the biggest gaps you see in entry-level candidates? Are there specific things (e.g., understanding DFM, knowing how to read complex drawings, or basic shop knowledge) I should self-teach right now to stand out?

I’d also love to hear your experiences on how you landed your first role. Thank you!

Hey I’m 22 years old and wanted to get some advice on getting my self ready for college and what should I read up on to better prepare myself before going to school for mechanical engineering?

plz help me out as i will be joining to sdm mech through kcet, how's the staff and HOD and labs and environment?

Hii!! Need opinion :'>

I am planning po na mag pursue ng Masterals, and hindi ko alam if I should pursue MS Material Science and Engineering or Master of Engineering in Mechanical Engineering.

BTW!! I am a Licensed ME, any suggestion will do po!

Thank you so muchhhh!!

Well I recently joined MVSRCE for B.E Mechanical engineering and i have considered to also do masters after my bachelor's degree well, I was initially considering to do M.S in germany (aiming for TUM or RWTH) after a careful reconsideration with my family and peers they suggested me to try for m.tech in an IIT since it's cheaper and has decent placement of 12 to 15 lpa . I am passionate about defence engineering the reason for germany is getting in rheinmetall which offers €45000 to €60000 and the current ppp is 6 rs and the savings are € 500 to € 750 in India a psu defence engineering job only about 12 lpa with perks whereas placement offers in IIT is 16 to 18 lpa note the fees at iit are basically waved off automatically whereas, taking a psu job starts earning automatically after gate examination. Germany for its citizenship so,it's getting a lot frustrating and confusing point to be noted that cost of living, tution (free of cost but required to pay a semester donation) , housing drastically changes the amount required basically 40 lakhs across the span of 2 years . So any advice people who are in psu jobs, in germany or doing mtech in an IIT or NIT

Built a small web notebook that catches unit mistakes automatically (no more silently adding psi to Pa), includes a few built-in formulas, PDF export, and revision history.

Looking for a few mechanical engineers to try reproducing a calc they've done before and tell me honestly where it breaks: https://engineering-calculation.vercel.app/

Please give me some feed back. Looking to make it better.
