1. In a system having a machine with a cutter for cutting a metal workpiece and a fixture for mounting the workpiece, a method of adjusting the feed rate and cutting speed for a machining operation to the characteristics of the material to be cut, the cut to be made, the fixture, the cutter, and the machine, said method comprising:

  • determining a first set of parameters, including a preliminary cutting speed and a preliminary feed rate, from the characteristics of the material to be cut, the cut to be made, the fixture, the cutter, and the machine;

    calculating the maximum allowable cutter force from the first set of parameters;

    calculating a base cutting speed from the first set of parameters;

    calculating the maximum feed rate from the first set of parameters, the maximum allowable cutter force, and the base cutting speed; and

    designating the calculated base cutting speed as the initial cutting speed, and the calculated maximum feed rate as the initial feed rate, for the machining operation.
