摘要： An indirect axis address command, nullAXnullcontrolled-axis numbernullnullcommanded movement amountnull, which can designate a controlled axis to be commanded through a controlled axis number is used. The controlled axes number can be stored in a variable by nullvariable null100nullAXNUM nullaxis addressnullnull, for example. In this way, it is possible to cause different axes to carry out the same operations by the same program by changing the axis addresses stored in the variables. Because the controlled axis is designated by using the controlled axis number, operation can be performed.

摘要翻译： 使用间接轴地址命令“AX [受控轴号] =指令移动量”，其可以指定通过受控轴号指令的受控轴。 例如，控制轴号可以通过“变量＃100 = AXNUM [轴地址]”存储在变量中。 以这种方式，可以通过改变存储在变量中的轴地址，使不同的轴通过相同的程序执行相同的操作。 由于通过使用受控轴号指定受控轴，因此可以进行操作。

摘要： A curve interpolation method capable of obtaining a curve approximating an original curve based on a sequence of command points within a tolerance set for the original curve, and performing interpolation on the obtained curve. Points Q1, . . . , Q2n are interpolated between respective two adjacent command points (P0, P1), (P1, P2), . . . , (Pnnull1, Pn) as shape-defining points. The shape-defining points are positioned within a tolerance width 2w set to the original curve. One shape-defining point and shape-defining points surrounding the one shape-defining point are successively selected and an approximate curve for the selected shape-defining points is successively created. The one shape-defining point is moved towards the approximate curve to determine a modified shape-defining point for the one shape-defining point. A smooth curve passing a sequence of the modified shape-defining points is created and interpolation for machining is performed on the created curve. Since the shape-defining points are positioned closer to an original target curve within a tolerance width set to the original curve than the command points, the created smooth curve passing the sequence of modified shape-defining points is well approximating the original target curve within the tolerance width.
