    摘要： If the angle α formed between the interpolated cutting surface perpendicular direction vector (It, Jt, Kt) and the interpolated tool direction vector (Ttx, Tty, Ttz) becomes smaller, movement of a tool becomes unstable. In this case, the tool diameter compensation vector (TCx, TCy, TCz) is set to the tool diameter compensation vector calculated in the immediately previous interpolation cycle, thereby preventing unstable movement. Further, in case of a block instruction where a distance between positions in cutting point instructions is large whereas distance of movement of linear axis control point is small, an execessive cutting may occur. To deal with this problem, movement of linear axis control point in a current block is stopped or converted into linear movement so as to prevent a loop-shaped movement of the linear axis control point.

    摘要翻译： 如果内插切削表面垂直方向矢量（It，Jt，Kt）与内插工具方向矢量（Ttx，Tty，Ttz）之间形成的角度α变小，则工具的运动变得不稳定。 在这种情况下，刀具直径补偿矢量（TCx，TCy，TCz）被设置为在前一个插补周期中计算出的刀具直径补偿矢量，从而防止不稳定的运动。 此外，在切割点指令中的位置之间的距离大的线性指令的情况下，线性轴控制点的移动距离小的情况下，有可能产生过度的切削。 为了解决这个问题，当前程序段中的线性轴控制点的运动停止或转换成线性运动，以防止线性轴控制点的环形运动。

    摘要： A numerical controller capable of moving a tool end point position to an accurate position in a five-axis machining apparatus. Compensation amounts are set, which correspond to respective ones of a linear axis-dependent translational error, a rotary axis-dependent translational error, a linear axis-dependent rotational error, and a rotary axis-dependent rotational error, which are produced in the five-axis machining apparatus. A translational/rotational compensation amount Δ3D is determined from these compensation amounts and added to a command linear axis position Pm. As the compensation amounts, there is used a corresponding one of six-dimensional lattice point compensation vectors, which are determined in advance as errors due to the use of a mechanical system and measured at lattice points of lattices into which the entire machine movable region is divided.
