6.10 Surface conditioning a way to digitalization

6.10.1 What does digitalization bring to surface conditioning?
Digitalization brings a significant number of advantages for several industries. The many benefits
provided are of different kinds:

- It increases benefits of companies due to the reduction of time production. Thus, factories
produce more and in a better quality.
- It leads to energy and money savings for companies. Indeed, automation leads to a waste
reduction and a general controlled shutdown of machines.
- It allows to improve performance. Information and reports from machines are analysed.
Companies collects knowledge thus, they can improve their way of producing.

However, a significant amount of variables has to be considered to digitalize the different processes of
surface conditioning. Digitalization leads to the training of qualified technicians to solve problems that
can occur during manufacturing.

Digitalization also raises the issue of data protection. Like other industries, data privacy is a significant
challenge. As more and more data are generated, questions arise. Where is data stored? Who has
access to it? Today, digitalization is mandatory for the companies to be competitive but at what cost?
