Cutting force calculations for drilling machine

Hi friends.... Pls help me out to find the cutting force calculations for a drilling machine and the calculations for design of lead screw......

    Calculation of Cutting Force, Torque and Power

    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)
