5-3 Examples of Usage of Tool-length Offset (NC-code Mode)
Example of Operations up to Starting Cutting
This section explains some important points about using an NC program to perform cutting with multiple tools.
Mount the Tools
Decide on the tools to use for draft cutting, finishing, and so on, and mount them in the magazine. Once you've mounted
them, it's important not to replace them with others until after you've finished cutting.

Register the Adjustment Values
Use automatic measurement of tool length or another method to register the adjustment values.

Specify the Commands in the NC Program
Specify the tools to use by their stocker numbers. At the same time, also specify the offset numbers assigned to the correspond-
ing stocker numbers. Depending on the NC program, offset No. 2, for example, may be assigned to stocker No. 1, making the
settings complex. Normally you should assign offset No. 1 to stocker No. 1, offset No. 2 to stocker No. 2, and so on.

Set the Z-axis Origin
It's a good idea to set the Z-axis origin only after you've registered the adjustment values. It's sufficient to make the setting
for just one of the tools in the magazine. For more information, refer to the following section.

Start Cutting
When you send the cutting data, the tool specified by the program is grasped and cutting starts. The tool-length offset is
applied at this time, and the cutting-in depth stays the same even after changing to the next tool.
