Rectangular pocket milling
The TNC cycle for rectangular pocket milling is available in the PO-
SITIONING WITH MDI
mode of operation.
The input data for milling a rectangular pocket can also be entered
as a “cycle” in a part program (see Chapter 7).
Select the “Pocket Milling” soft key on the second soft-key row and
enter the required data. These data can usually be taken from the
workpiece drawing (side length, depth of the pocket, etc.).
The TNC controls the machine tool and calculates the tool path for
area clearance.
For the procedure and input data required for programming a rec-
tangular pocket, see Chapter 7.
