With my little benchtop CNC mill I have to be patient while separating my part from its stock. So I was thinking if I could drill a bunch of holes (drilling cycles with drillbits) to remove chunks of material before zipping through with endmill. I am under the impression that drilling is more efficient than endmilling for removing the same amount of material.
Also my endmill will not have to engage at full surface and will be cutting at 25-60% contact with material so I will feed it fater.
Or may be for circular pokets it would make sense to predrill and then interpolate the rest with a boring tool.
Again the onjective is to remove chunks fast and then finish with endmill(s) going faster.
Am I on a right track to reduce the cutting cycle?
