4.3 Grooving cycle – CYCLE93
Function
With the grooving cycle you can make symmetrical
and asymmetrical grooves for longitudinal and
traverse machining on straight contour elements.
You can machine both external and internal grooves.
Sequence of operations
The depth infeed (towards the base of the groove)
and infeed across the width (from groove to groove)
are distributed evenly and with the greatest possible
value. If the groove is being machined on an inclined
surface, travel from one groove to the next follows
the shortest path, i.e. parallel to the cone on which
the groove is being machined. The safety distance to
the contour is calculated in the cycle.
