摘　　要：火炮身管膛线数控加工的可靠性算法,其系统软件先读取C轴插补中间状态寄存器、C轴给定值寄存器和Z轴反馈值寄存器之值。再计算并判断刀具实际与理论运动轨迹的等式成立与否,由此判断硬件插补器工作是否正常。从而保证拉刀运动轨迹的正确性和可重复性,确保膛线加工的可靠性。At first, the system software of reliability algorithm read the value from interpolation mediacy register, theoretical register of c axis, and feedback register of z axis in NC processing of artillery rifling. At second, the system make use of the values to calculate the equations about actual trochoid and academic trochoid of cutter moving and deduce whether the hardware interpolation component executing normally or not. In order to keep the reliability of rifling processing, the validity and iteration of broach moving track are made sure before processing.
