9.4 Exalmple of a customized macro
Within the control, the customized macro is stored either in the NC program store or within an EPROM.
The “Bolt hole circle”-cycle 68 requires the following entry parameters:
01 = Number of holes
02 = Radius of pitch circle
Q3 = X-coordinate for pitch circle centre
Q4 = Y-coordinate for pitch circle centre
05 = Set-up clearance for Z-axis
Q6 = Drilling depth iin Z-axis
Q7 = Feed rate for drilling
The first hole of the pitch circle is located on the O”-axis of the X-Y-coordinate system. The variable
parameter program which is stored derives the hole spacing via the total number of holes and executes
machining.
