Basic operation
1. Drilling operation. Only if it has been programmed.
After analyzing the geometry of the pocket with islands, the tool radius and the angle of the path
programmed in the roughing operation, the CNC will calculate the coordinates of the point where
the selected drilling operation must be performed.
2. Roughing operation. Only if it has been programmed.
It consists of several surface milling passes, until the total depth programmed has been reached.
On each surface milling pass, the steps below will be followed depending on the type of
machining that has been programmed:
Case A:
When the machining paths are linear and maintain a certain angle with the abscissa axis.
It first contours the external profile of the part. If the finishing operation has been selected on
the cycle call, this contouring is performed leaving the finishing stock programmed for the
finishing pass.
Next the milling operation, with the programmed feed and steps. If, while milling, an island is run
into for the first time, it will be contoured.
After the contouring and the remaining times, the tool will pass over the island, withdrawing along
the longitudinal axis, to the reference plane, and will continue machining once the island has
been cleared.
