Controlled parting using lag error monitoring G917

Refer to your machine manual.
The machine tool builder determines the scope of
function and behavior of this function.
G917 monitors the path of traverse. The controlled parting function
(cut-off control) prevents collisions caused by incomplete parting
processes.
The control stops the slide when the tensile force is too high and
generates an interpreter stop.
Parameters:
H: Tensile force
D: Axis number (X = 1, Y = 2, Z = 3, U = 4, V = 5, W = 6, A = 7 ,
B = 8, C = 9)
K: Incremental distance
O: Err. evaluation
O = 0: Error evaluation in expert program
O = 1: The control issues an error message
During parting control, the parted workpiece moves in the +Z
direction. If a lag error occurs, the workpiece is defined as not cut
off.
The result is saved in the variable #i99:
0: Workpiece was not correctly cut off (following error detected)
1: Workpiece was correctly cut off (no following error detected)
Lag error monitoring is not activated until the
acceleration phase has been completed
The feed rate override is not effective during cycle
execution
