„ the drilling cycles G71, G72, G74.
„ the milling cycles G840...G846.
G47 without parameters activates the parameter values (machining
parameters 2, ... – safety clearances).
Safety clearance G147
G147 defines the safety clearance for
„ the milling cycles G840...G846.
„ the drilling cycles G71, G72, G74.
Parameters
P Safety clearance
G47 replaces the safety clearance set in the machining
parameters or that set in G147.
Parameters
I Safety clearance to the milling plane (only for milling
operations)
K Safety clearance in approach direction (feed)
G147 replaces the safety clearance set in the parameters
(machining parameters 2, ...) or that set in G47.
