Automation Automation is the use of machines and technology to make processes run on their own without manpower Technique, method, or system of operating or controlling a process by highly automatic means, as by electronic devices, reducing human intervention to a minimum Defined as appropriate use of machines, electronic devices and computer software for the construction work Increase the productivity and Quality Reduces the duration and laborious work Increases the safety and flexibility 09-03-2024 18 MHB402-RMVS-HITS-20-21-RMKP
- 19. Automation & Robotics Robots are a piece of equipment that can perform a variety of tasks with programming Automation is a term that is used for special purpose machines or systems that are designed to perform a specific task. 09-03-2024 19 MHB402-RMVS-HITS-20-21-RMKP
- 20. Automation & Robotics • Robots: Automated Intelligent machine to do a Physical Task • Automation: computer software, machines or other technology to carry out a task which would otherwise be done by a human worker 09-03-2024 20 MHB402-RMVS-HITS-20-21-RMKP
- 21. ACTUATORS • Actuator is a device which is used to actuate a process. • Actuate is to operate the process. • Actuators are the device used for converting hydraulic, pneumatic, and electrical energy into mechanical energy. • Mechanical energy used to get the work done. Actuators perform functions just opposite to that of the pump. • Used for lifting, tilting, clamping opening, closing, metering, mixing and turning, and for many other operations
- 22. . An actuator is a component of machines that is responsible for moving or controlling a mechanism or system. Switching devices – mechanical switches, eg. relay and solid-state switches, e.g. diodes, thyristors and transistors app – switch on or off electrical devices Solenoid – type devices used to actuate valves of hydraulic and pneumatic systems. (flow control) Drive systems – DC motor, AC motor and stepper motor. ACTUATORS (Contd.) Example: In a CNC milling machine, there may be an electrical signal output from the CNC controller to move the milling table in the x direction for a certain length. There you need an actuation system.
