-which sequence or order is the best way to machining first?
-what are the consideration to chose the best order or sequence?why?
-any journal, article, or prove?

You need to get hold of a programming manual for a CNC machine. It will tell you about fixturing (how you hold the job down), tooling and the process generally. You could talk to a CNC production engineer who is responsible for the production of a part and ask him about the processes involved in the final part
Hope this helps

I need to calculate shipping based on weight – I can visualise the size but not weight

I’m a CNC machinist, hard to say an average, depending on lathe or mill, big or small, I run mazak quik turns, which i think are about 3000 pounds.
I’ve worked on other lathes that were in the 5000 & 6000 range.
I’ve also worked on mills that were 10 – 15000 pounds.
If you know the make and model of the machine, maybe do a google search for the mfg. and check their dimensions and weight.

What does it mean when the motors are in series or parallel or unipolar?

CNC motors are stepping motors
if wired in parallel they will step equally

they cannot be wired in series!
unipolar and bipolar is something else
it relates to the driver and the winding of he motors

to get more torque you need a bigger motor and bigger driver
Or to gear down!

i want to open my own engine rebuilding shop, mainly for motorcycle. I,ve googled but the machinary very expensive such CNC/ peterson etc. Since theres not many competition in my area, what i,m planning is the very basic, "old school" engine rebuilding you may call it.I do have some basic knowledge and planning to take basic machinary course ( boring/honing) etc.

kind of work i,m planning to do are;
1. cylinder boring
2. cylinder honing
3. valve job
4. maybe some lathe machine job

please, tell me what machine and tools for the kind of work above

thanks
I,m from Indonesia, Bandung city. in my town we have very little good boring and honing shop. i just want to enter and still wide open boring and honing business.

I’m a community college student, and we have a cylinder boring machine that costs $20,000 in itself! My partner spent $4000 on just Snap-On tools alone!

So…I think you’re going to need a little more money O_O

I would suggest reading this article,
"Beginner’s Guide to CNC Conversions," at
http://www.dakeng.com/CNCconvert.html

This will cover the basic elements that need to be included in a conversion, whether it be a kit, or you acquire your own parts to do the conversion.

I was just curious about how you find customers to get work for the machines. Also, if you have any advice in starting a business let me know.

Typically you would know someone who has work needed to be done, or that is too busy, and is willing to job out some of the overflow, or already jobs out the parts, they can not make.
Contract Bids from Defense and Aero-space Co. are good, but hard to get. Web Sites like www.machinetools.com and Emachinetools.com will allow you (Free) to post adds saying that you have machines, and need work.
Advise on starting a shop. Purchase machines that can do more than you think you will need, do to the fact we usually estimate low. Also, purchase only good, new machines, and from reputable dealers or the manufacture. Do not get cough up in leasing three machines when you only need one, due to a fast talking salesman. Get good Cad Software and be Cad/Cam Savvy. Always keep learning, and be open minded to the customers point of view, and the way the do the job.
I sell machinery, both CNC and Conventional, so if you ever have any questions, you may always contact me

Maintenance on the machine.. change the coolant..

change the hydraulic oil..

adjust the gibs in the slides…

How many volumes would you like…

when all else fails read the manual that came with the machine…

Willing to pay up to 5,000 if necessary for a good one. Are there any that work with metal And Wood… and other stuff like stone or plastic? What other gear do I need? What’s the best training? I applied for machine tool technology at my local tech school. Will they tech me the manual stuff or are they focused on CBC software stuff? Are there any hobbysized CNC Lathes? Any simple man powered lathes still out there?
*sp CNC
I want to make pseudo-weapons, Geiger-esque sculptures, complex mandalas, useable art like vases. Detail heavy stuff.

How much are and where do I get raw material? Wood isn’t hard to find. What about metal? I’m even thinking about carving discarded scrap metal and plastic!
Would I be better off teaching myself off books? If so what titles and where do I find said books?

I would expect that tech schools teach what is requested from businesses in the area, so you need to ask what is offered.
Metal requires a much stronger lathe than wood with stronger motors gears and bearings. Tools on a wood lathe are hand held on a rest while metal tools must be mounted to withstand the forces involved. Most metal lathes are much more complicated than wood lathes and involve screw positioning and drives for the tool mounts so precision can be held. You could work wood on a metal lathe, but messy as wood chips and oil required for machining mix.
But from what you say you want to make, a lathe is pretty much worthless. Lathes make round things, the only thing you mention that is naturally round is vases and those are not normally turned from metal on a lathe from a solid block. Even if I have missed something, do you really want to put unknown metal chunks in your expensive lathe?
I think you need to do more research because what you may want is metal forming, which can involve lathe forming but the lathe is more like a wood lathe, but also includes a lot of other metal handling skills, most of which are not done specifically by hand (like fenders are shaped with an English wheel, not hammered to shape)
You might contact some of the people involved in Renaissance faire re-enactors and making armor, decorations, and costumes for them as the skills they use are more in line with your desires. If you search on line for "making armor" "making helmets" you will encounter terms like raising and sinking metal and repousse http://users.ticnet.com/mikefirth/repousse.htm Many of these skills are discussed more in silversmithing books (or under whitesmithing) rather than machining metal.
edit
the Society for Creative Anachronism is people devoted to being really, really accurate about old details, including making stuff the old fashioned way. They do intense research and write papers on what they found – and set up web sites to talk about it.
