-- (Chow? Process Interruptions l Galactica makes camera housings used in satellites. Galactica's- process begins with a Computer Numerically Controlled (CNC) machine that drills into a block of- metai to make the camera housing. The CNC machine requires a 30 minute setup time before the production of a batch of camera housings can commence. Each block requires 10 minutes of drilling on the. CNC machine. Next. the batch of camera housings are chemically treated in a series of baths. There is unlimited capacity in the treating stage. Finally. a worker must manually attach the various buttons and components to the metal housing. The assembly takes 120 minutes per housing per worker. no setups. and Galactica has 6 workers trained to do this task. Assume unlimited demand. The process is shown below. Note there are buffers between the stages of the process. Drilling on CNC machine -- u Chemical Treatment-n Assembly If the batch size is 30 housings. what would be the CNC machine's approximate capacity {in housings per hour)? 16. 5 housings per hour k ' 3 housings per hour ' 8.5 housings per hour 5.5 housings per hour "l
