# G83 Face Peck drilling cycle

G83-Face Peck drilling cycle.

There are (2) parameters related to G83.

Param #5101 bit2 (RTR) “High speed” if “0” then the pecks do NOT come out

of the hole, they only back up the amount of Param #5114 “G83 Retract”,

to break the chip and then start feeding again.

Param #5114 “G83 Retract -200” is the amount to rapid back into the

hole from the last peck for clearance.

I suggest…

Param #5101 bit2 = “1” -Rapid out of hole every peck.

Param #5114 “G83 Retract” = “-200” =-.02 from last peck. No decimal.

G83 X(U)__C(H)__Z(W)__R__Q__P__F__K__M__

R= Distance from intial Point to R Point in radius

P= Dwell time at bottom of Hole

Q= Depth of cut for each cutting feed

F= Feedrate in IPM(G98) or IPR(G99)

K= Number of Repitions (When needed)

Note: G0,G1,G2 or G3 Cancel G83 Our factory recommends G80 to cancel

Z1. =Z position of the bottom of the hole

F.001 =Feed in IPR or IPM

R-.03 =Rapid from current Z position the R amount incrementally.

If starting at Z-.05 and R=.03 then the Z axis rapidly

positions to “Z-.02” and after every peck Z retracts to

the same position “Z-.02”. If you use “R-.03” it is the same

as “R.03”

Q2000 =Peck amount -same as .2 but not allowed a decimal point

P0 =Dwell amount at the bottom of the hole. You can just leave

P off the command line if you want

K = Number of Repeats
