3.4 Elongated holes on a circle - LONGHOLE
Programming example
Machining elongated holes
With this program you can machine 4 elongated
holes 30 mm in length and with a relative depth of 23
mm (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 20 mm in
the YZ plane. The initial angle is 45 degrees, the
indexing angle is 90 degrees. The maximum infeed
depth is 6 mm, the safety clearance is 1 mm.
