Manufacturing Technology

In this Module we will be taking a brief look at

the following:

1.CNC Routing

2.CNC Milling

3.CNC Lathe Work

4.CNC Laser Cutting

5.Rapid Prototyping

6.3D Scanning (reverse engineering)

CNC Router

It is now possible to design and manufacture true three dimensional

shapes in schools. Modern machines in schools such as the Denford,Boxford or Roland Router can be used to manufacture products

designed in software such as Solid Works with a combination of

accuracy and speed. The router can shape a variety of materials

including Perspex, wood, MDF and model board.

3D modeling brings modern design and manufacturing

technology into the school workshop.

2. CNC Lathe Work

CNC Lathe

Using a Lathe it is possible to turn complex designs in metal based on

a design imported form drawing packages such as solid works.

Step one:

You must first create a CAD drawing of the Part you want to Manufacture:

In this case we have used Solid works to draw a Bottle stop.

Bottle Stop

To create a revolved part a half profile is drawn as a sketch:

Bottle Stop

This the can be used as the basis for a revolve feature:

Here is the completed part File:

The completed part File is then exported as a DXF into the Lathe Software :

2. CNC Milling

CNC Mill

It is now possible to design and manufacture true three dimensional

shapes in schools. Modern machines in schools such as the Denford,Boxford or Roland Mill can be used to manufacture products

designed in software such as Solid Works with a combination of

accuracy and speed. Unlike a router a Mill is used to machine metal.

3D modeling brings modern design and manufacturing technology

into the school workshop.

4. Laser Cutting:

With a Laser cutter various materials including plastic wood

and glass can be cut at etched to an extremely high tolerance.

Also unlike cutting materials by hand every part will be exactly

the same size.

5. Rapid Prototyping:

All the other manufacturing techniques we have seen today involve taking

a material and cutting parts away to make a finished product but with

Rapid Prototyping a part is built up in hundred of layers of durable ABS

plastic.

6. 3D Scanning:

Not all parts that are

manufactured are designed on

CAD software. Some are made

first by hand then scanned andreproduced accurately with CNC

machinery.
