6.4 Nesting
Example for exercise:
Group of four holes at three positions (see page 6-4). but with three different tools
f
\
Machining sequence:
Countersinking - Drilling -Tapping
L /
The drilling operation is programmed with oycte
1: PECKfNG tsee page 841 and cyczie 2:
TAPPING (see page 8-12~. Tha groups of holes
are approach& in one subprogram, and the
machining is perbrmed in a second subprogram.
Coordinates of the first hole in each group:
@ X = 15mm Y = IOmm
@ X = 45mm Y = 60mm
@ X = 75mm Y = IOmm
Spacing between
holes:
IX = 20mm IY =20mm
Hole data:
Countersinking ZC= 3mm 0 = 7mm
Drilling ZD= 15mm 0 = 5mm
Tapping ZT= IOmm 0 = 6mm
