    • A horizontal machine tool (1) includes a base frame (10) where workpiece support faces (11c) for supporting a workpiece are formed at front portions; an X-axis saddle (20) attached to a back-face portion (12b) of the base frame (10) through an X-axis movement mechanism (50) universally slidably in a left-right direction; a Y-axis saddle (30) attached to the X-axis saddle (20) through a Y-axis movement mechanism (60) universally slidably in an up-down direction; and a spindle device (40) attached to the Y-axis saddle (30) through a Z-axis movement mechanism (70) universally slidably in a front-rear direction. According to this configuration, it is possible to make a whole of the horizontal machine tool a small size and lightweight and to enhance machining accuracy of the workpiece.

    • A machine having X- and Y-axis linear moving axes and a pivot axis B for rotationally pivoting a pivot member having a tool arranged at a distal end thereof about an axis parallel to a Z axis is controlled. A moving command obtained by a command program commanded by a position expressed by X, Y, and Z in a three-dimensional orthogonal coordinate system is subjected to an interpolation process to calculate amounts of interpolation movement (ΔX, ΔY, and ΔZ) of the respective orthogonal axes. An amount of rotation Δθ of the pivot axis required for moving the tool by the amount of movement ΔY in the Y-axis direction is calculated. An amount of correction movement δx for canceling the movement in the X-axis direction caused by the rotation Δθ of the pivot axis B is calculated. Values (ΔX+δx), Δθ, and ΔZ are outputted to the X axis, the pivot axis B, and the Z axis, respectively.
    • 控制具有X轴和Y轴线性移动轴的机器以及用于旋转地枢转枢转构件的枢转轴线B,枢轴构件具有围绕平行于Z轴的轴线的远端设置的工具。 对由三维正交坐标系中由X,Y和Z表示的位置所命令的命令程序获得的移动指令进行内插处理,以计算内插运动量(DeltaX,DeltaY和DeltaZ) 各自的正交轴。 计算用于将工具移动移动量ΔY在Y轴方向上所需的枢转轴的旋转量。 计算用于消除由旋转轴线B的旋转角度引起的在X轴方向上的运动的校正移动量的量。 值(DeltaX + deltax),Deltatheta和DeltaZ分别输出到X轴,枢转轴B和Z轴。
