逻辑

Aristotelian logical theory is not only profound and far-reaching but also permanent to the influence of the later generations.

亚里士多德的逻辑研究对后世的影响是深远而长久的。

The principles of system working, hardware circuit, logic of controlling and arithmetic of data processing are described in detail.

详细描述了系统工作原理、硬件电路及其控制逻辑和数据处理算法。

At the machine level, the processing involves performing arithmetic and logical operations on data value.

在机器程度中，过程牵涉执行算数和逻辑的运算。

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。

Each expression may perform arithmetic or logic operations, test conditions, etc.

每个表达可能执行算术或逻辑运算，测试条件等状况的资料都提供了投入，以及表达的结果。
