Circular hole pattern on face
A circular hole pattern is to be machined on the face of the workpiece
with the Drilling, axial cycle. This machining operation requires a
traversable spindle and driven tools.
The center of the pattern is entered in Cartesian coordinates.
Since this example is to illustrate how you drill a through hole, the hole
end point Z2
is programmed such that the tool has to drill all the way
through the workpiece before it reaches the end point. The
parameters "AB" and "V" define a feed reduction for both pre-drilling
and through-boring.
Tool data
 WO = 8 (tool orientation)
 DV = 5 (drilling diameter)
 BW = 118 (point angle)
 AW = 1 (The tool is a driven tool)
