Plunging strategy
Q366: Type of plunging strategy.
n
0 = vertical plunging. In the tool table, the plunging
angle ANGLE for the active tool must also be defined
as 0. The TNC will otherwise display an error
message.
n
1 = helical plunging. In the tool table, the plunging
angle ANGLE for the active tool must be defined not
equal to 0. The TNC will otherwise display an error
message.
