Assembling a car

First,the parts are delivered by truck or rail to the delivery area of the car assembly plant.from here,some parts are taken to the body shop,and others parts are transported to the chassis line.the parts are carried around the plant by forklift trucks or conveyor belts.In the body shop,the panels are welded to the frame to form the body of the car.this is done by more 400 robots.

Then the body is taken to the paint shop.Here it is cleaned and painted by robots.special clothig is worm by the robots to protect the paint.after this,the bod is checked by humans workers to look for defaults.Next,the painted body moves along a conveyor belt to the trim line and many parts are added to it.for example,the instruments panel,the air conditioning system,the heating system and the electrical wiring are all installed here.the windscreen is inserted by robots using laser guides.

Meanwhile,in the chassis line,components are added to the chassis.first,the chassis is turned upside down,to make the work easier.then the fuel system,the transmission,the suspension,the exhaust system,the axles and the drive shaft are all installed.next the chassis is turned over(rightside up).the ingine islowered into the chassis and connected to it.

Now the chassis and the body move simultaneously to the final assembly line.here the body is attached to the chassis,and all the final parts are added.the tyres and the radiator are added here.the hoses are connected,and the radiator and air conditioner are filled with fluid.the car’s central computer is also installed here.

Lastly,the finished car and all electrical systems are tested.the car is filled with fuel and the engine is started for the first time.the car is put on special rollers to test the engine and the wheels.if it passes the test,the car is finally driven out of the assembly plant.

Tunnel drill:Cutting the rock surface,

the face of the cutter has 85 teeth.each tooth is 60cm long.the cutter face rotates about seven times a minute.when it rotates,the teeth cut large circles into the surface of the rock.Collecting the rocks:pieces of rock fall to the ground.they are collected by large scoops.they are then dropped into chutes.when the cutter face rotates upwards,the rocks fall onto conveyor belts.they are carried to the rear of the machine.moving the cutter:hidrulic cylinderscpush the body of the cutter slowly forwards.as it moves forward,stee shoesvmove outwards and grip the tunnel walls.at the same time two legs push down and lift the machine off the floor.supplying the electricity:fifteen electric motors supply the machine with 6,375 horsepowerthe power is connected to the cutters by means of a 13,800-volt cable.streangthening the roof:there are two drills attached to steel arms.these are located immediately behind the cutters.when the machine moves forward,holes are drilled into the roof of the tunnel.then the holes are filled with bolts and cement.this strengthens the roof.controlling the movement:the machine operator sits in a cabin at the heart of the machine.here he controls its speed and direction.video cameras monitor the cutter and the tunnel.
