    • A 1st program orthogonal coordinates system in which two axes whose movable directions are not perpendicular to each other are set, one of the axes is set as an inclination reference axis, information data based upon an angle between the two axes whose movable directions are not perpendicular to each other are set and the movable direction of the inclination reference axis agrees with the direction of the command axis of the program orthogonal coordinate system, and a 2nd program orthogonal coordinates system in which the movable direction of the other axis that is not the inclination reference axis agrees with the direction of the command axis of the program orthogonal coordinates system are prepared. By selecting one of the 1st and 2nd program orthogonal coordinates systems, an optimal tool can be selected in accordance with a machining patern, the machining can be practiced with the optimal shaft feed and machining precision can be improved.
    • 设置其中可移动方向彼此不垂直的两个轴的第一程序正交坐标系,其中一个轴被设置为倾斜参考轴,基于可移动方向不垂直的两个轴之间的角度的信息数据 并且倾斜基准轴的移动方向与程序正交坐标系的指令轴的方向一致;第二程序正交坐标系,其中不是倾斜的另一轴的可移动方向 参考轴与程序正交坐标系的指令轴方向一致。 通过选择第一和第二程序正交坐标系中的一个,可以根据加工参数选择最佳工具,可以利用最佳的轴进给实现加工,并且可以提高加工精度。
