Measuring cut G809
Cycle G809 performs a cylindrical measuring cut with the length 
defined in the cycle, moves to the breakpoint for measuring and stops 
the program. After the program was stopped, you can manually 
measure the workpiece.
Parameters
X
Starting point X
Z
Starting point Z
R
Measuring cut length
P
Measuring cut oversize
I
Breakpoint Xi for measuring: Incremental distance to starting 
point of measurement
K
Breakpoint Zi for measuring: Incremental distance to starting 
point of measurement
ZS
Workpiece blank starting point: Collision-free approach for 
inside machining
XE
Departing position X
D
Number of an additive compensation to be active during the 
measuring cut
V
Measuring cut counter: Number of workpieces after which a 
measurement is performed
Q
Machining direction
0: -Z
1: +Z
EC
Machining location
0: Outside
1: Inside
WE
Directions
0: Simultaneously
1: First X, then Z
2: First Z, then X
O
Approach angle: If an approach angle is entered, the cycle 
positions the tool over the starting point taking into account the 
safety clearance and from there plunges at the specified angle 
to the diameter to be measured.
