Please note while programming:
Before a cycle definition you must have programmed
a tool call to define the touch probe axis.
The smaller the angle, the less accurately the TNC
can calculate the dimensions of the stud. Minimum
input value: 5°
If you reference parameter Q330 to a turning tool,
the following applies:
– Parameters Q498 and Q531 have to be described
– The information of the parameters Q498, Q531,
for example from Cycle 800, has to match this
information
– If the TNC compensates the turning tool,
the appropriate values in line DZL and DXL,
respectively, are compensated.
– The TNC monitors the breakage tolerance which
is defined in column LBREAK
If you reference parameter Q330 to a milling tool, the
information of the parameters Q498 and Q531 has
no effect
