The power must be available at the rotational speed used (see the power curve of the machine as a function of rotational speed), while taking into account the following remark:
One must remember that the spindle power of the machine must be greater than the cutting power because, in approximate terms, we have:
Ptotal = Pc + Pv (no-load power at the rotational speed used)
EN AW 2017 aluminium alloy, monobloc carbide drill:
d = 6 mm, vc = 200, f = 0.3. This data gives: (kc = 1050, see previous table)
