CONTEXT
A Tunnel Boring Machine (TBM) also known as a mole is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through anything from hard rock to sand. Tunnel diameters can range from a metre (done with micro-TBMs) to almost 16 metres to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs.
Tunnel boring machines are used as an alter ....etc

Aerodynamicists use wind tunnels to test models of proposed aircraft. In the tunnel, the engineer can carefully control the flow conditions which affect forces on the aircraft. By making careful measurements of the forces on the model, the engineer can predict the forces on the full scale aircraft. And by using special diagnostic techniques, the engineer can better understand and improve the performance of the aircraft.

Wind tunnels are designed for a specific purpose and speed range and there is a wide variety of wind tunnel types and model ....etc

Jig-Boring Machine
a metal-cutting machine for finishing holes, planes, and slots with a highly precise location of centers or surfaces without the use of special attachments for tool alignment.
Jig-boring machines are used for boring, drilling, counter-sinking, reaming, milling, and other types of finishing in individual and small-scale production during the manufacture of cutting and measuring tools, jigs, dies, and key components of machines and instruments. Devices with stable and adjustable end gauges and indicator sensing units are use ....etc

hi , this is samurai007 and i would like to get a detailed presentation on the topic TUNNEL BORING MACHINE. I need to give a powerpoint presentation on a mechanical related topic and i think this topic fulfills my needs.
Please cover following topics-
1. working
2. applications fields (elaborate)
3. advantages and disadvantages
4. latest developments
5. comparison with old traditional methods. etc.

I am expecting a detailed presentation or an elaborate content (must include pictures)

ppt on smart tunnel

The Stormwater Management And Road Tunnel (SMART Tunnel), E38, is a storm drainage and road structure in Kuala Lumpur, Malaysia, and a major national project in the country. The 9.7 km (6.0 mi) tunnel is the longest stormwater tunnel in South East Asia and second longest in Asia.

The main objective of this tunnel is to solve the problem of flash floods in Kuala Lumpur and also to reduce traffic jams along Jalan Sungai Besi and Loke Yew flyover at Pudu during rush hour. There are two components of this tunnel, the stormwate ....etc
