Specifying Start Axes
Plunge milling tools can not cut with their centers. Therefore, in Plunge milling the tool makes its first plunge within a region along a predrilled axis, which must be located at the deepest point of the region.
When you choose Start Axes from the SEQ SETUP menu, the system displays the START AXES menu with the following options:
• Add—Select or create a datum axis to serve as a predrilled axis.
• Remove—Select a previously defined Start Axis to remove.
• Remove All—Remove all Start Axis definitions.
• Show—The system highlights all Start Axes in cyan.
You have to specify a Start Axis for each milling region. The system will then compute the tool path for the region based on the SCAN_TYPE and using the Start Axis as a start point.
