Repeating recessing cycle G740

G740 is programmed before G860 to repeat the recessing contour
defined in Cycle G860.
Parameters:
X: Start pt. X – shifts the starting point of the recessing contour
defined by G860 to this coordinate
Z: Start pt. Z – shifts the starting point of the recessing contour
defined by G860 to this coordinate
I: Length – distance between the starting points of the
individual recessing contours (in X)
K: Length – distance between the starting points of the
individual recessing contours (in Z)
Q: Number of recessing contours

Repeating recessing cycle G741

G741 is programmed before G860 to repeat the recessing contour
defined in Cycle G860.
Parameters:
X: Start pt. X – shifts the starting point of the recessing contour
defined by G860 to this coordinate
Z: Start pt. Z – shifts the starting point of the recessing contour
defined by G860 to this coordinate
I: Length – distance between the first and last recessing
contour (in X)
Ii: Length – distance between the recessing contours (in X)
K: Length – distance between the first and last recessing
contour (in Z)
Ki: Length – distance between the recessing contours (in Z)
Q: Number of recessing contours
A: Angle at which the recessing contours are arranged
R: Length – distance between first and last recessing contour
Ri: Length – distance between the recessing contours
O: Flow
0: Roughen all recesses then finish all recesses (default:
previous behavior)
1: Machine each recess completely before machining the
next one
