Match the following factory layout approaches to the descriptions. Product 1. Workers and equipment move around product Functional/Process 2. Common operations or processes are grouped together Cellular 3. Each manufacturing area specialises in the production of a set of similar products Fixed position 4. Collection of workers and stations are designed specifically for the product being produced Question 4 (10 points) Match the following descriptions to their type of automation. - High investment for a custom-engineered system - Continuous production of variable mixtures of products - Medium Production Rates - Flexibility to deal with product design variations - High investment in general purpose equipment - Lower production rates than fixed automation 1. Flexible Automation - Flexibility to deal with variations and changes in product configuration 2. Fixed Automation - Most suitable for batch production 3. Programmable Automation - High initial investment for custom-engineered equipment 4. Manual manufacturing - High production rates - Relatively inflexible in accommodating product variety - Very flexible and adaptive - Low predictability in time for production - Only capable of relatively low-to-medium production rates. A robot is working at high speed performing repetitive tasks. The process is fully automated and humans only rarely need to go into the area fo maintenance. The parts coming into the work zone arrive on a conveyor, are processed and then leave on a second conveyor. Considering the need for safety, cost and access, which of the following would be the most suitable form of guarding? Physical (e.g. cage or wall) with opening's for the two conveyors and an access door for maintenance. Rope barriers Painted walkway at a safe distance and red painted floor where the robot operates. Pressure pads around the work cell Laser light curtain around all four sides, but with "deadzones" to allow the conveyors to operate. Question 6 ( 30 points) Calculate the minimum distance to the hazard zone of a machine assuming: 1. the walking speed of a person is 1600mm/s. 2. the maximum time for a machine to stop after a demand from the control systems is 0.16s 3. the response time of the detector and control system is 0.01s 4. the intrusion distance is 850mm Your
