Determine materials used here and its manufacturing processes

Click For Summary

Discussion Overview

The discussion revolves around identifying two objects and their manufacturing processes as part of a manufacturing technology assignment. Participants explore the materials used and the methods of production, including casting, joining, and machining, while seeking clarification and guidance on the topic.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • Shubhash seeks help identifying two objects and understanding their manufacturing processes.
  • Participants request context and previous research efforts from Shubhash to guide the discussion.
  • Joe identifies the objects as an engine fuse holder and a plumb-bob, noting the difficulty in determining their materials due to their historical manufacturing.
  • Joe mentions that the manufacturing processes likely involve casting, joining, and machining, but expresses challenges due to their novice status in the subject.
  • One participant suggests observing the objects physically to gather clues about their materials, such as checking for magnetism and surface characteristics.
  • Another participant lists common metals used in manufacturing and suggests methods to identify them based on color, density, and hardness.

Areas of Agreement / Disagreement

Participants generally agree on the need for clarification and exploration of the materials and processes involved, but there is no consensus on the specific materials or methods due to the exploratory nature of the discussion.

Contextual Notes

Participants have not provided detailed observations or research findings, which limits the depth of the discussion. The complexity of the assignment and the historical context of the objects are acknowledged but remain unresolved.

Who May Find This Useful

Students studying manufacturing technology or related fields may find this discussion relevant as it addresses practical challenges in identifying materials and processes in manufacturing.

Guys,

I have two objects here, need to know what are they and the processes they go thru to manufacture.

Thanks,
shubhash

Hi Shubhash, welcome to PF.

Can you give us the context for this question - where does it come from?

Also, do you have any ideas about what the objects might be?
 
it was an assignment for manufacturing technology course, I am supposed to figure out the material used and the build of it...

Moderator's note: thread moved from Materials & Chemical Engineering forum.

To the OP: please provide your thoughts and how far you have gotten with this assignment. Members are not supposed to do your homework assignment for you, instead we provide hints, guidance, and clarification.
 
Guys,

The question is a little tedious and elaborated. I just need clarification on what the hell I am dealing with here please.

As you have been reminded of already, it is against the PF rules to give you answers to homework or coursework. That is supporting cheating, and we do not do that here on the PF.

Tell us what you have found so far. What research have you done so far (asking the question on web forums is not doing research)? What sources of information have you used to look at how items like this can be made?
 
Please tell us what you observe in each picture. That will help us orientate a suitable reply.
 
Sorry there, I am the group member of shubash.

So far we have found out so far that both things, 1 is engine fuse holder, then the 2nd 1 is plumb-bob(look like a top). Somehow, we need to find out the material used to manufacture it, but it is hard for us to figure it out whether it is in book or in internet as both things had been manufacture for quite a long time.

The 2nd problem i would like to mention is about the manufacturing process, which both must involve casting, joining, and machining process. It is a little bit hard for us as we were just started studying the subject " introduction to manufacturing" course.

Welcome to the PF.

Could you post some of the links to information that you've found so far for these two items? Also, have you gone to your local hardware store to look at plumb bobs, to see what they feel like, and to determine whether they are magnetic or not. Why would that help you determine the material they are made out of?

The more common metals that many objects are made from would be iron, steel, stainless steel, brass, aluminum, or copper.

Color, density, and whether it is magnetic offer clues as to which metal you have. It may be helpful to scratch off the surface oxide layer to see the metal's true color, and what it takes to scratch it can give information about the hardness -- another clue.
