{i} process of making something mechanical; replacement of human labor with machine labor (also mechanisation)
Use of machines, either wholly or in part, to replace human or animal labour. Unlike automation, which may not depend at all on a human operator, mechanization requires human participation to provide information or instruction. Mechanization began with human-operated machines to replace the handwork of craftspeople; today computers are frequently used to control mechanized processes
the act of implementing the control of equipment with advanced technology; usually involving electronic hardware; "automation replaces human workers by machines"
