Consider a man-machine system consisting of an operator and a die press that performs a repetitive task. The work elements of the task together with associated normal times are as follows: 1. Operator removes the pressed unit from the die press (0.2 min) 2. Operator walks to inspection area for quality control of the pressed unit (0.1 min) 3. Operator checks pressed unit for defects (0.1 min) 4. Operator files to smooth rough edges of the pressed unit (0.2 min) 5. Operator places pressed unit on conveyor for further processing of the pressed unit (0.1 min) 6. Operator returns back to die press to press the next sheet metal (0.1 min) 7. Operator cleans the die press with compressed air, sprays lubricant into die (0.4 min) 8. Operator places sheet metal inte die press, pushes the START button to press it (0.2 min) 9. The die press die cycles automatically to punch the sheet with the die to produce a pressed unit (1.2 min) Assuming that the work elements given above are performed sequentially in the given order, construct a man-machine activity chart for the task Operator Time Machine Operation Moving Inspection Holding Idle nine Time
