5- Consider the following data about handling two different machines by one operator:

Loading the turning machine: 3 minutes -
Automated operation by the turning machine: 12 minutes
Unloading the turned part: 2 minutes
Loading the drilling machine: 3 minutes
Automated operation by the drilling machine: 8 minutes
Unloading the drilled part: 2 minutes

Going between the two machines is assumed to be 0.5 minutes and inspection time of the drilled or turned part is 1 minute. It is desired to:
a. The cycle time
b. Idle time of the operator in each cycle
C. What is the percentage of idleness of drilling machine
d. Draw the man-machine chart for this operation assuming that the turning machine to be the number 1 and the drilling machine to be the number 2
