The operator can display or change a value stored in CNC internal
memory by key operation on the screen (See V–11).

Machining requires the use of a tool.
The tool has the tool dimension (length). When a workpiece is machined,
the tool movement route depends on the tool dimensions.
By setting tool dimension data in CNC memory beforehand,
automatically generates tool routes that permit any tool to cut the
workpiece specified by the program. Tool dimension data is called the
offset value (See Section V–11.4.1).
