DTE XBOX 360 project

 so far in dte we whave been working on fixing and modify an xbox 360 . so far we have come up with our plan  and our concept design we have remove the dust and completely dissembled it .

we plan on cutting a hole in it hydro dipping it and attaching it to a monitor and making it a semi portable all in 1 Xbox setup.

to far we have fixed the software issuse with the xbox once we had done that we cleaned the dust off once we did that we removed the motherboard from the frame because we were going to hydro dip the frame but we have changed our plan to hydro dip the case and add led lighting and also hydro dip the monitor . we have started cut some of the cover out so that you can see the inner workings we also  plan on making so you can see the disc as it spins

here are some of the concept designs we are using as our inspirations

How to use Taps and die sets in engineering .CMM2

What is tap and die used for in Engineering 

A tap and die are use for cutting threads in or onto a piece of metal

TAP

When would you use a tap for a thread 

You would use a tap for a internal thread inside of a hole

Does the hole need to be bigger or smaller , explain why .

When tapping a thread the hole that is being tapped needs to be smaller than the tap because when tapping  material is being removed from the inside of the hole forming the thread

METRIC TAPPING THREAD CHART.

What are the different types of tap ( taper, intermediate, bottoming) explain the difference between them 

a taper tap is a tap that is tapered so that you can ease in to cutting the threads.

a Bottoming tap has next to no taper because it is designed to thread all the way to the bottom of the tap

a intermediate tap has between 3-5 tapered threads that is more than a bottoming tap and less than a taper tap

.

Die

When would you use a Die for a thread 

you would use a die for making the external part of the thread

Does the Bar need to be bigger or smaller , explain why .

The Bar has to be larger than the die because you are cutting in to the bar and not add material to the outside of the bar.

some die's you can use on a lathe and some that you have to turn by hand
