    • A method of preparing a program for numerically controlled machine tools is disclosed involving the use of an aid comprised of a model representing the workpiece to be machined and the tooling to perform the machining process, mounted to have a capability for relative movement along axes corresponding to the relative movement occurring during the machining process. Standardized preset tools and tool holders are established for use in the actual machining processes and corresponding model representations of such standardized preset tools and tool holder combinations are provided which can be located in the model in the same relative position as the corresponding actual tools and tool holders will be located in the machine tool. In preparing the NC program, a machinist prepares a machining process, selecting tools and holders from the available standardized preset tools, and specifies the various machining steps, spindle speeds, in-feed rates, etc. to be utilized in machining the workpiece. The programmer, utilizing the model as an aid for creating a physical representation of the actual machining sequence, then prepares a control program listing, utilizing built-in scales along the axes of motion provided in the model to establish directly by reference to such scales the position of the machine tool at various stages in the sequence specified by the machinist. The final dimensional cuts are calculated from the dimensions of the workpiece specified in the drawing. The actual implementation disclosed corresponds to programming of a turret lathe with a two-dimensional model thereof utilized, including a representation of the turret indexing movement.
    • 公开了一种用于数控机床的程序的制备方法,其涉及使用由代表待加工的工件的模型构成的辅助工具和用于执行加工过程的工具,其被安装成具有沿相应于 在加工过程中发生的相对运动。 建立了标准化的预设工具和刀架,用于实际的加工过程,并提供了这种标准化预设刀具和刀架组合的相应模型表示,该组合可以位于模型中与相应的实际刀具和刀架相同的相对位置 将位于机床中。 在准备NC程序时,机械师准备加工过程,从可用的标准化预设刀具中选择刀具和夹具,并指定用于加工工件的各种加工步骤,主轴转速,进给速率等。 程序员利用该模型作为创建实际加工顺序的物理表示的辅助,然后准备一个控制程序列表,利用在模型中提供的运动轴线内置的刻度,通过参考这些尺度来直接建立 按照机械师指定的顺序在不同阶段的机床位置。 最终尺寸切割是根据图中规定的工件的尺寸计算的。 所公开的实际实现对应于使用其二维模型的转塔车床的编程,包括转塔分度运动的表示。

    • A tool-operating copy of a magnetic tape program for a machine tool is made from a master tape that has been produced by a large-scale computer. The master tape is scanned and a desired program therefrom is read into the memory of a small interfacing computer. The output of the interfacing computer is used to reproduce the selected program in a cartridge tape unit which provides the actual tool-operating copy. While the copy is being made, information temporarily stored in the interfacing computer is printed out for visual identification. Portions of the program determined to be in error by visual insepction, or portions desired to be changed, are fed back into the interfacing computer through a keyboard device to correct the appropriate parts of the program contained within the interfacing computer memory and also correct the cartridge operating copy.
    • 用于机床的磁带程序的工具操作副本由大型计算机生产的主磁带制成。 主磁带被扫描,并且所需的程序被读入小型接口计算机的存储器中。 接口计算机的输出用于在提供实际的工具操作副本的盒带单元中再现所选程序。 当正在进行复印时,打印出临时存储在接口计算机中的信息用于视觉识别。 通过视觉干扰或希望改变的部分确定为错误的程序的部分通过键盘装置反馈到接口计算机中,以校正包含在接口计算机存储器中的程序的适当部分,并且还校正该盒 操作副本。
