# Q2: How does automation impact the need for human workers in industries using industrial machinery?
Automation, driven by advanced industrial machinery and robotics, changes the nature of work rather than necessarily eliminating jobs entirely. While automation may reduce the need for manual labor in repetitive or hazardous tasks, it increases the demand for skilled workers to operate, program, maintain, and repair the more complex machinery. It also creates new roles in data analysis, system integration, and overseeing automated processes. The focus shifts from manual tasks to technical and supervisory roles.
# Q3: What are the main considerations for maintaining industrial machinery?
Effective maintenance of industrial equipment involves a combination of strategies: preventive maintenance (scheduled tasks like lubrication and inspections), predictive maintenance (using data to anticipate failures), and reactive maintenance (repairing breakdowns). Key considerations include following manufacturer guidelines, training maintenance staff, keeping detailed records, managing spare parts inventory, and implementing condition monitoring programs to identify issues early. The goal is to minimize unplanned downtime, extend machine life, and ensure safe operation.
