In this article, we describe how to use G83 cycle to drilling peck in CNC lathe machines (CNC Turning Machines) with all details and examples.

G83 Cycle Introduction

G83 command (G83 cycle) is used for drilling holes that are deep in CNC Lathe (CNC Turning machines) that cannot be drilled at one time or that may result in tool breakage, chip jamming. If another coordinate is given afterwards, it moves there and the cycle continues to work as described above until the G80 command is issued.

The G83 command (G83 cycle) should be used to prevent jamming of the chip during drilling deep holes and to drain the chip out of the part. As you can imagine, trying to drill holes in one hole using G81 command in deep holes will have consequences such as the chip getting stuck in the drill and the tool breaking.

G83 Cycle Format

G83 X(U)_ C(H)_ Z(W)_ R_ P_ Q_ F_ K_ M_ ;

Parameters

X_ C_ or Z_ C_ : Hole position data
Z_ or X_ : The distance from point R to the bottom of the hole
R_ : The distance from the initial level to point R level
P_ : Dwell time at the bottom of a hole
Q_ : Depth of cut for each cutting feed
F_ : Cutting feedrate
K_ : Number of repeats (When it is needed.)
M_ : M code for C-axis clamp (When it is needed.)
