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 point pattern
is entered in Cartesian coordinates.
Since this example is to illustrate how you drill a through hole, the
End point drill 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-rate reduction for both spot
drilling and through-boring.
Tool data
TO
= 8 – Tool orientation
DV = 5 – Drilling diameter
BW
= 118 – Point angle
AW = 1 – The tool is a driven tool
