G37 Chessboard Hole Cycle
Command Format: G37 Xx Yy IΔx Pnx JΔy Kny
Description:
Chessboard hole cycle.
X, Y: the first position to be drilled (G90/91 is influential)
I: hole interval in X axis
P: number of holes in X axis
J: hole interval in Y axis
K: number of holes in Y axis
G37 drills P*K holes in XY plane with XY as start position. The space between adjacent holes is
Δx in X axis, while in Y axis, the space is Δy, G0 speed used when moving from one hole to another
one.

Machine tool moves from P, first to A, then drills 10
holes with hole interval as 50mm in X-axis until to
B, then moves 100mm in Y+ direction to C, and
then drills 10 holes until to D in X axis. The rest can
be done in the same manner until J is reached with

Customized Canned Cycle
The user can customize G coeds by writing a subprogram in public.dat.
Subprogram no. 200~999 is used by internal parse engine. The code range of M command is
200~599, while that of G code is 600~999.
Therefore, G code (0~99) plus 600 is regarded as the corresponding subprogram.
