    • A numerical control unit for a machining apparatus which operates under the control of a machining program comprising a plurality of blocks, such blocks being adapted to define a command or instruction for specifying and automatically controlling the relative movement between a machine tool and a workpiece with respect to one or more of linear and rotational axes, and being modifiable at starting-point and end-point areas in a single block to specify desired variations in relative movement or feedrate. The feedrate may be controlled on the basis of preset rules within a single block without dividing a machining path into a plurality of blocks for controlling the feedrate, the preset rules being changeable by an operator whereby his machining know-how can easily be incorporated into the machining program. Rules incorporating machining know-how are set in a knowledge storage section, an inferring section is provided independently of the knowledge storage section to ensure ease of additions and corrections to the rules, and the inferring section synthesizes the results of inference provided by a plurality of rules and deduces a final conclusion, whereby complex control can be easily achieved with various factors taken into consideration. Rules set in the knowledge storage section can be described in a production rule format, allowing a final conclusion to be achieved by fuzzy inference. In such case, efficient processing is enhanced by providing that inference is only made as to rules judged as necessary to be executed, membership functions in the conclusion part of a fuzzy rule are represented in a simple shape pattern, the results of all selected rules are considered and the relative significance of the selected rules are reflected on a conclusion.
    • 一种用于在包括多个块的加工程序的控制下操作的加工装置的数字控制单元,所述块适于定义用于指定和自动控制机床和工件之间的相对运动的命令或指令, 到一个或多个线性和旋转轴,并且可以在单个块中的起始点和终点区域修改以指定相对运动或进给速度期望的变化。 可以在单个块内基于预设规则来控制进给速度,而不将加工路径划分成用于控制进给速度的多个块,预设规则可由操作者改变,由此他的加工专有技术可以容易地并入 加工程序。 在知识存储部分设置包含加工专有技术的规则,独立于知识存储部分提供推断部分,以确保对规则的容易添加和更正,并且推断部分综合由多个 规则并推导出最终结论,从而可以通过考虑各种因素轻松实现复杂的控制。 在知识存储部分设置的规则可以以生产规则格式描述,允许通过模糊推理来实现最终结论。 在这种情况下,通过提供仅对于被判断为需要执行的规则的推断来加强有效处理,则以简单形状图案表示模糊规则的结论部分中的隶属函数,所有选定规则的结果为 考虑了所选规则的相对意义,并得出结论。
