BCD码的低3位各位只能是0~9，如果是16#A~16#F则会出错。计数器的预设值PV是0~999的BCD码，可以用格式为C#的常数（C#1~C#999）作为计数器的预设值。下图用MW42提供计数器的预设值PV，如果用MOVE指令将十进制数348（对应的十六进制数为16#15C）传送给MW42，进入RUN模式时，操作系统将它转换为BCD码时出错（16#15C不是BCD码），不能切换到RUN模式。输入预设值348时，应改为将C#348传送给MW42，它会自动地变为W#16#348，当然也可以直接输入16#348。

以平端面的四分点作为基准点，先利用基准刀进行断面一刀运行退出和车外圆一刀运行退出，在选用部件加工所用刀具，将其放置在平端面四分点处，如此可以确定起刀点，进行数控机床加工。以平端面四分点处为基准点，精准对刀在每次基准刀退出时记下屏幕显示数据，加工到直接到达对应坐标即可。综合以上内容的分析，可以充分说明数控机床加工中有效运用对刀技巧来进行对刀操作是非常有效的，可以提高对刀操作的准确性，为高质高效的进行数控加工创造条件。
