Droop control ON Okuma Control
G65 Droop control ON
The feed axis is controlled to follow
the computed value. For this
reason, the actual axis position is behind the computed value. The droop control prohibits to issue the next
function unless the delay falls within the droop range specified by the
parameter, in order to suppress the delay of the
axial position.

Mirror image coordinate selection check Okuma Control
G62 Z-axis mirror image coordinate
selection check
Whether the Z-axis program coordinate
system is used as the fundamental or mirror image coordinate system is instructed
at the head of program. Actually, the direction of coordinate system is
selected by the parameter and, when the program instruction mismatches with the
parameter selection, an alarm occurs.

When this is instructed to the same
block as the S command this function as the spindle speed maximum command. In other cases, it functions as the origin
shift command. Spindle speed maximum instruction this restricts the maximum
spindle speed that can be instructed by the program.

Cutter radius compensation Right
G42 Cutter radius compensation:
Right
For lathe machining, this functions as
the tool nose radius compensation-right.
This is instructed when the center of tool (center of nose radius)
passes the right-hand side of machining face, viewing from the direction of
relative movement of tool against the work.
Tool nose radius compensation Left
G41 Tool nose radius compensation:
Left
For lathe machining, this functions as
the tool nose radius compensation-left.
This is instructed when the center of tool (center of nose radius)
passes the left-hand side of machining face, viewing from the direction of
relative movement of tool against the work.
Fanuc Panel Keys
Address keys The area of the MDI keypad that allows an operator to enter letters and special characters into the control. ALARM keys Keys located on the machine panel that display alarm information for the machine panel. These keys are different from the alarm keys associated with the control panel. AUTO key The key on the CNC machine that changes the operation mode to auto. Auto mode allows an operator to call up and execute a part program stored in memory. Auto mode is sometimes called memory mode on some CNC controls. AUTO mode The mode that allows an operator to call up and execute a part
