2.1 Drilling cycles
RPA (retraction path, in abscissa)
Under this parameter you define a retraction movement
in the abscissa, which is executed after the final drilling
depth has been reached and oriented spindle stop has
been performed.
RPO (retraction path, in ordinate)
Under this parameter you define a retraction movement
in the ordinate which is executed after the final drilling
has been reached and oriented spindle stop has been
performed.
RPAP (retraction path, in applicate)
Under this parameter you define a retraction movement
in the boring axis which is executed after the final
drilling has been reached and oriented spindle stop has
been performed.
POSS (spindle position)
Under POSS the spindle position for the oriented
spindle stop which is performed after the final drilling
depth has been reached is programmed in degrees.
Further notes
With the SPOS command you can perform an oriented
spindle stop of the active master spindle. The angular
value is programmed with a transfer parameter.
Cycle CYCLE86 can be used if the spindle to be used
for the boring operation is technically able to go into
position-controlled spindle operation.
