Overview

The geometries of the machining tool must be taken into consideration when executing a part
program. These are stored as tool offset data in the tool list. Each time the tool is called, the
control considers the tool offset data.
When programming the part program, you only need to enter the workpiece dimensions from
the production drawing. The control then independently calculates the individual tool path.
