3.4 Elongated holes on a circle – LONGHOLE
Programming example
Machining elongated holes
With this program you can machine four elongated
holes 30mm in length and with a relative depth of
23mm (difference between the reference plane and
the base of the elongated hole) that lie in a circle
with the center point Z45 Y40 and a radius of 20mm
in the YZ plane. The initial angle is 45 degrees, the
indexing angle is 90 degrees. The maximum infeed
depth is 6mm, the safety distance is 1mm.
