G243 Radial peck drilling canned cycle

`X`	Diameter at the bottom of the hole
`R`	R plane, diameter
`Q`	Peck depth, incremental
`I`	First peck depth
`J`	Amount each peck is reduced
`K`	Minimum peck depth
`P`	Dwell at the bottom
`F`	Feed rate
`Z`	Z position of the hole
`C`	C axis angle
`Y`	Y position, Y axis lathes

How it works

Modal, group 09. Cancel with G80.

Example program

T1010 (.25 RADIAL DRILL, LIVE)
G98 (FEED PER MINUTE)
M133 P1500 (LIVE TOOL FORWARD 1500 RPM)
G00 G54 X3.5 Z-.75 C0 M08 (ABOVE 3.0 DIAMETER)
…

The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.

Watch out for

Do not use Q together with I, J and K.
Setting 52 and Setting 22 work the same as in G83.
X is the diameter at the bottom of the hole and R is a diameter too.
