A lathe cutter with a power of 3 kW removes chips 500 mm long per minute. what is the cutting force of the cutter.

During time t, energy will be supplied to the machine with power N:
W = Nt (1).
This energy will be equal to the work that the cutter will perform, acting on the workpiece with a force F over a length l:
A = Fl (2).
From the right-hand sides we compose the equality:
Nt = Fl.
F = Nt / l = (3000 W * 60 s) / 0.5 m = 360 000 N = 360 kN.
Answer: 360 kN.
