In order to improve NC machining precision this article analyzes the effects of cuttingforce on NC machining precision by means of simulation, and builds up the mathematical models ofCK7815 feed drive system and radial action force of cutting feed, in order to study the effects ofcutting load torque and radial cutting force on work pieces processing precision. The simulationresults illustrate that cutting load torque and radial cutting force have respectively effects on axialprecision and radial precision of work piece. The bigger is cutting load torque, the bigger is axialerror. The smaller is cutting process coefficient and the higher is converting spring stiffness of latheand tool, the smaller is radial error. In practice NC machining precision is improved by trying todecrease the cutting load torque and cutting process coefficient and increase converting springstiffness
