Drill bit Vs End mills

House

Upcut & Downcut

In an Upcut type end mill the teeth on the flute will point upwards. This means that the end mill is cutting and drawing out the wood through the flute.
This is good for cutting deep into the stock. But this leaves a bad surface finish on the top of the surface.

Making something big

This week, we used a CNC mill to make something that's big and needs to be cut precisely.
In my case, I built study table out of a MDF that will be assembled with screws or glue.
The bench is about 120x45x40cm

What did I used to make it

1.CNC mill (I used Velocity Cnc router machine wich is computerrised).
2.wood (I had2440 x 1220 x 30mm MDF).
3.Files and Sanding paper

Designing

This is the sketch part of my week eight assignment and it is also part of my final project
House

I made the design in 123D AUTODESK DESIGN, an open source CAD software.

I started with the top part, it is basically a plain rectangle.

House

then i went ahead with extrusion

House

copy paste the other part and i used the snapping tool to snap

House

another rectangle for both sides

House

extrusion and snaping

House

after snapping both sides i tried to change the appearance depending with the colour of my material

House

drawing a sketch for the drowers

House

i went ahead with extrusion again

House

changed the appearance

House

i wanted two drowers

Finally i desided to change the appearance of my drowers to make it apealing

I was not able to cut the table, since it was costly but i did the plan B part shown below

I found some metal tube in the store and desided tochange my design

Finaly after i have chamfer
House

i imported the design to the cnc software and later did my settings
