1. G Function Description
1.2.52 G137.1: CHESS TYPE HOLE CYCLE
Command form:
G137.1 X Y I P J K ；
X, Y: coordinates of starting point, effective by G90/91.
I: X axis interval, unit is decided by G70/G71, if the interval value is
positive ,then go through positive direction from starting point, if it is
negative ,then go through negative direction.
P: interval of X axis direction, range 1~9999.
J: interval of Y axis direction
K: number of Y axis direction, range 1~9999.
Description:
The starting point is specified (X,Y), we get the interval at horizontal
direction of X axis, and drill nx chess type holes. We get the interval at
horizontal direction of Y axis, and drill ny chess type holes.
Example:
ny = 8
Y interval 100mm
300mm
50.0
nx = 10
X interval 50mm
G91；//use incremental mode
G81 Z-10.0 R5.0 K0 F20；
//execute drilling cycle, cutting feedrate 20mm/min, depth of each hole
10 mm, then return to initial point
