Assembly processes refer to the methods used to combine various components into a finished product. These processes can be manual, where workers physically put parts together, or automated, using machines and robots to increase efficiency and precision. Common examples include the assembly of automobiles, electronics, and furniture. Different assembly techniques, such as line assembly and batch assembly, cater to specific production needs. Line assembly involves a sequential flow where each worker or machine performs a specific task, while batch assembly allows for the production of multiple items simultaneously. These processes are crucial for ensuring quality and consistency in manufacturing.
