Sleeve monitoring G930

Refer to your machine manual.
The machine tool builder determines the scope of
function and behavior of this function.
G930 activates/deactivates Sleeve monitoring. When monitoring
is activated, the maximum Contact force for one axis is defined.
Sleeve monitoring can be activated for only one axis per NC
channel.
G930 moves the defined axis by the Incremental distance K until
the defined Contact force H has been reached.
Parameters:
H: Contact force in daN – the contact force is limited to the
value entered
Q: Axis number (X = 1, Y = 2, Z = 3, U = 4, V = 5, W = 6, A = 7 ,
B = 8, C = 9)
K: Incremental distance
Application example:G930 is applied to use the counter spindle
as a mechatronic tailstock. In this case the counter spindle is
equipped with a dead center and the Contact force is limited
with G930. A prerequisite for this application is a PLC program
from the machine tool builder that enables the user to operate the
mechatronic tailstock in the Manual and Automatic operating mode.
Lag error monitoring is not activated until the
acceleration phase has been completed.
Tailstock function: With the tailstock function, the control moves
up to the workpiece and stops as soon as the Contact force has
been reached. The remaining path of traverse is deleted.
