  1. Find the "bottleneck" in the drilling operation.
  2. Measure the time taken for one part to pass through the bottleneck and another to reach the same place.
  3. Take the reciprocal.
  4. "Robert is your mother's brother".

It is indeterminable with data provided. What material are the rods made of? What material and type of drill? Is the bit the type that drills and taps at the same time? Or is it separate operations to drill then to tap? Is both operations being preformed on the same piece of equipment? Equipment used? Coolant applied? Set up time?

Don;t repeat the same question in multi forums,

It eats up the bandwidth.

The people normally scan through the forums for something interesting.
