2、ing Systems,Definition of Manufacturing System,We define a manufacturing system to be a collection of integrated equipment and human resources, whose function is to perform one or more processing and/or assembly operations on a starting raw material, part, or set of parts.,Definition of Manufacturin
3、g System,The integrated equipment includes production machines and tools, material handling and work positioning devices, and computer systems. Human resources are required either full time or periodically to keep the system running.,Components of a Manufacturing System,Production machines Material
4、transport Systems Computer Control System Human Resources,Production machines,Manually operated production machines Semi-automated production machines Fully automated production machines,Material transport System,Three functions: (1)Loading-involves moving the work units into the production machine
5、or processing equipment from a source inside the station. (2)Positioning-provides for the part to be in a known location and orientation relative to the workhead or tooling that performs the operation.,Material transport System,(3)Unloading- When the production operation has been completed, the work
6、 unit must be unloaded, that is, removed from the production machine and either placed in a container at the workstation or prepared for transport to the next workstation in the processing sequence.,Computer Control System,Communicate instructions to workers Download part programs to computer-contro
