Order Size for drilling: * The Manual press needs 15 min for set up‚ in addition to 0.08 min for every hole. Knowing that the typical circuit board has 500 drilled holes‚ then run time will be 0.08*500 = 40 min / board. Therefore‚ time taken to drill N boards manually will be equal to : 15 + 40(N) * On the other hand the CNC drill needs 240 min for set up‚ in addition to 0.004 min for every hole. So run time will be 0.004*500 = 2 min / board. Then the time taken to drill N boards by CNC drill
