Press the Pattern linear soft key
Press Pattern linear to machine drilling patterns in which the
individual features are arranged at a regular spacing in a straight line
on the face.
The parameters of the hole are also requested.
Use the following parameter combinations to define the:
 Starting point of pattern:
 X1, C1 or
 XK, YK
 Pattern positions:
 Ii, Ji and Q
 I, J and Q
DRILLING PATTERN LINEAR, AXIAL
Cycle parameters
X, Z Starting point
C Spindle angle (C-axis position)—(default: current spindle
angle)
Q Number of holes
X1, C1 Starting point of pattern in polar coordinates
XK, YK Starting point of pattern in Cartesian coordinates
I, J End point of pattern in Cartesian coordinates
Ii, Ji: Pattern spacing (incremental)
