A Manufacturer of gears & gear drives has following specifications of the diameter of the finished gears. The nominal value is 300 mm, USL = 300.85, LSL = 299.15 mm. The vendor development department proposed two processes X & Y for manufacturing these gear drives. After several trial runs , both the process were statistically stabilized. Performance are given as below: The Production department wishes to know which of the 2 process are suitable for serial manufacturing. Compare the relevant measures and offer appropriate recommendation to start serial manufacturing.
