Face Milling - Cycle71 - Siemens SINUMERIK 808D User Manual

Pl ane definition
Milling cycles generally assume that the current workpiece coordinate system has been defined by selecting a plane (G17,
G18 or G19) and activating a programmable frame (if necessary). The infeed axis is always the third axis of this coordinate
system.
See the following illustration for plane and axis assignment:
Me ssages with regard to the machining state
During the execution of the milling cycles, various messages that refer to the machining status are displayed on the screen.
The following messages are possible:
● "Elongated hole <No.>(first figure) being machined"
● "Slot <No.>(other figure) being machined"
● "Circumferential slot <No.>(last figure) being machined"
In each case, <No.> stands for the number of the figure that is currently being machined.
These messages do not interrupt the program execution and continue to be displayed until the next message is displayed or
the cycle is completed.
