除了长度，将刀 具插入刀库需要引入的另一个尺寸就是直径。

For this, the physical dia meter of the tool is not considered, but a codified dimension of the sa me, in accordance with the Siemens convention. 

于此，刀 具的物理尺寸不被考虑，而是按照西门子的惯例，使用刀 具的编撰尺寸。

Occupation is identified in semi-locations i.e. in those with a value equal to half the step between the said locations.

占有被定义为半个位置，如上述两个位置之间的值相当于半步。

A tool can have a minimum dimension of  1-1 (left - right), equivalent to occupation of only its cone. 

一个刀 具可具有zui小的尺寸1-1（左-右），相当于只占它的锥体部分。

Each individual value for left or right occupation ranges from  1 to  7, with the two figures not necessarily having to coincide with each other.

 It is therefore also possible to define unbalanced tools. 

每个左或右位的独 立值从1到7不等，两个数字不一定要相互吻合。因此也可定义非横刀 

 具。

Exa mple: Defining a tool with dimension D equal to 3-4 (on a chain whose step between locations is equal to 145 mm), implies the following:

例如：定义一个刀 具，尺寸等于3-4（刀链上两位置间的步距等于145mm），包含如下：

The left part of the tool, starting from the cone axis, is less than (145/2)*3 mm;
