1970s: Computer-Integrated Manufacturing (CIM) |
 |
Since the 1970s there had been a growing trend towards the use of computer programs in manufacturing companies. Especially functions related to design and production, but also business functions should be facilitated through the use of computers.
Accordingly the CAD/CAM technology, related to the use of computer systems for design and production, was developed. CAD (computer-aided design) was created to assist in the creation, modification, analysis, and optimization of design. CAM (computer-aided manufacturing) was designed to help with the planning, control, and management of production operations. CAD/CAM technology, since the 1970s, has been applied in many industries, including machined components, electronics products, equipment design and fabrication for chemical processing.
To enable a more comprehensive use of computers in firms the  CIM (computer-integrated manufacturing) technology, which also includes applications concerning the business functions of companies, was created. CIM systems can handle order entry, cost accounting, customer billing and employee time records and payroll. The scope of CIM technology includes all activities that are concerned with production. Therefore in many ways CIM represents the highest level of automation in manufacturing.

Punch card, 1801
Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, the punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology for processing statistical data retrieved from the US census in 1890, thus speeding up data analysis from eight to three years. His application of Jacquard's invention was also used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with writing and calculating, administrative purposes account for the beginning of modern automatic data processing.
Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone applied them as a medium for the preparation, storage, and transmission of data for the first time. By their means, telegraph messages could be prepared off-line, sent ten times quicker (up to 400 words per minute), and stored. Later similar paper tapes were used for programming computers.
