Innovation in Industrial Production:
Cutting, carving and shaping/ moulding have been the
a Scan the article. Find and write the names of traditional production process for many years. Cutting
the traditional manufacturing processes in the technique can be defined as removing a piece from

blanks. an entire block by using a special knife, scissors, or a
machine. In the 20th century, laser cutting machines
1 took the place of the traditional cutting machines
rapidly. Laser cutters are the computer driven tools
that use a laser to cut a given material perfectly
and cleanly. Laser cutters are far more reliable and
faster than the traditional cutting machines. They are
much more capable of cutting different materials in
desirable thickness. However, they have difficulty in
cutting reflective metals like copper and brass. Laser
2
cutters have been widely used in textile industry in
recent years as well due to their ability to cut stretchy
and easily distorted materials.
The most convenient example to define carving can
be sculpturing. In order to make the definition clear,
an artist works on a block of stone and gives a shape
of his/ her sculpture by carving it with a carving knife.
3 It has been one of the first processing techniques
applied by humans in ancient times. With the
invention of the CNC (Computer Numerical Control)
machines, hand carving tradition is facing extinction
due to the fact that it demands a lot more effort and
time. CNC machines are computer driven tools that
interpret the designs as instructions for cutting and
