Contouring Mode (Deceleration) 'G09'
The interpolation condition G09 is used to adjust the end-of-block velocity
in such a way that as stop could be performed using the maximum veloc-
ity change without ramp defined in the axis parameters.
•
Position deviations can be reduced at NC-block transitions by using
the interpolation condition G09.
•
Machining using G09 requires more time, and the surface quality can
be adversely affected by the free cutting marks.
•
G09 is the power-on default. It is active and latched until it is overwrit-
ten by a G08. G09 is reset automatically at the end of the program
(RET) or by the BST, M02, M30 command.
Note:
The Maximum Feedrate Change w/o Ramp is specified by the
machine builder in the axis parameter Cxx.017.
