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.
