    • Step data are sequentially read out from a conversational program created in a conversational format. The processor 13 determines whether or not leaning control in the step is possible. When the leaning control is possible, a learning start command is added to the start of the program to create and output an NC program in the step. Also a learning end command is added to the end of the NC program in the step. Conversion into the NC program is performed for each of steps. When a learning control automatic ON/OFF operation is selected to all the steps, a learning control start command and a learning control end command are added to the start and the end of the converted NC program when learning control of all the steps can be performed.
    • 从会话格式创建的对话程序中顺序读出步骤数据。 处理器13确定步骤中的倾斜控制是否可能。 当倾斜控制成为可能时,将在程序开始处添加学习开始命令,以创建并输出NC程序。 此外,在步骤中,将NC程序的结尾添加学习结束命令。 对每个步骤执行转换到NC程序。 当对所有步骤选择学习控制自动ON / OFF操作时,在可以执行所有步骤的学习控制时,学习控制开始命令和学习控制结束命令被添加到转换的NC程序的开始和结束 。

    • A path table operation is performed while updating the reference positions. When a read-out command in the path cycle table is read out, the reference positions are withdrawn and reset, and the respective axial positions at the time of the initiation of the path cycle command are stored. From the next period, the target positions are determined by adding the positions at the time of initiation to the respective axial positions corresponding to the reference positions stored in the path cycle table, and a path table operation is performed. A single path cycle table is sufficient for storing commands for portions to be repeatedly worked.
    • 在更新参考位置的同时执行路径表操作。 当读出路径循环表中的读出命令时,引用和复位参考位置,并且存储在路径循环命令开始时的相应的轴向位置。 从下一个周期中,通过将启动时的位置与对应于存储在路径周期表中的基准位置的各个轴位置相加来确定目标位置,并执行路径表操作。 单个路径循环表足以存储要重复工作的部分的命令。

    • A numerical controller capable of mitigating mechanical shock caused by tool compensation while a machine tool is operated according to table data. X- and Z-axis path tables Tx, Tz store X- and Z-axis positions corresponding to reference positions (time or spindle position). A tool compensation table Tt stores X- and Z-axis compensation amounts (tool compensation numbers) associated with the respective reference positions. At every predetermined period, X- and Z-axis path table interpolators read command positions from the path tables Tx, Tz based on the reference position, and obtain command motion amounts by interpolation. X- and Z-axis tool interpolators read compensation amounts from the tool compensation table Tt based on the reference position, and obtain compensation motion amounts by interpolation. Adders add up the command motion amounts and the respective compensation motion amounts to drive respective motors. The tool compensation amounts are gradually varied, whereby mechanical shock does not occur.
    • 一种数控机床,能够根据表格数据,在机床运行时减轻刀具补偿引起的机械冲击。 X轴和Z轴路径表Tx,Tz存储对应于参考位置(时间或主轴位置)的X轴和Z轴位置。 刀具补偿表Tt存储与相应参考位置相关联的X轴和Z轴补偿量(刀具补偿号)。 在每个预定时段,X轴和Z轴路径表插值器基于参考位置从路径表Tx,Tz读取命令位置,并通过插值获得指令运动量。 X轴和Z轴刀具内插器根据参考位置读取刀具补偿表Tt的补偿量,并通过插补获得补偿运动量。 加法器将命令运动量和相应的补偿运动量相加以驱动相应的电机。 刀具补偿量逐渐变化,从而不会发生机械冲击。

    • An axis position is commanded according to data stored in a memory table where the axis position is stored in association with a reference value consisting of time or spindle position. For commanding the shape of a circular arc, a start and end points, a center position, and a radius of the circular arc and designation of sine or cosine are set in advance in the memory table. Then, a movement command for connecting the start point and the end point with the circular arc is output to each of axes, using a trigonometric function defined by the center position of the circular arc, the radius of the circular arc and the designation of sine or cosine, which have been set.

    • A numerical controller capable of reducing machining time in synchronization control machining. A workpiece already rough-machined into a shape of a gear and a tool are rotated in synchronism. Proximity limit distance Lt ensuring that the workpiece and the tool do not interfere with each other, approach amount Ap required to bring the workpiece and the tool into a positional relationship for performing normal gear machining (condition in which the workpiece engages with the tool), and phase shift amount corresponding to the depth of cut are given as commands. In parallel with approach motion, phase adjustment motion for making the workpiece face a tooth space of the tool is performed. When the approach motion progresses by the proximity limit distance Lt, if the phase adjustment is completed, the approach motion is continued without interruption. If not, the approach motion is interrupted, and resumed after the phase adjustment is completed. After the approach motion is completed, phase shift is performed to give a cut, and machining is performed. When cutting loads become a certain value or smaller, it is determined that the machining is completed. Since the approach motion and the phase adjustment are performed concurrently and completion of machining is automatically determined, the machining time can be reduced.
    • 一种能够减少同步控制加工中的加工时间的数值控制器。 已经粗加工成齿轮和工具的工件的工件同步旋转。 接近极限距离Lt确保工件和工具彼此不干涉,使工件和工具进入正常齿轮加工(工件与工具接合的状态)所需的位置关系所需的接近量Ap, 并且相应于切割深度的相移量作为命令给出。 与进场运动并行,执行用于使工件面对工具的牙齿空间的相位调整运动。 当接近运动进行接近极限距离Lt时,如果相位调整完成​​,则连续运动不间断地继续。 如果没有,则进场运动中断,并在相位调整完成​​后恢复运行。 进场动作结束后,进行相移切断,进行加工。 当切削负载变为一定值或更小时,确定加工完成。 由于进行运动和相位调整同时进行,并且自动确定加工完成,因此可以减少加工时间。
