Centroid G10 G‑Code: Mastering Parameter Settings for CNC Machining

Centroid G10 – Parameter Setting

Centroid G10 G code allows cnc machinist to set parameters for different program operations.

Many machine parameters can also be set with the Centroid G10 G-code.

Centroid G10 – Parameter Setting

Centroid G10 Tool Offset Settings – CNC Mill

G10 H5 R-1.3    ; Sets tool length offset #5 to -1.3 in the offset lib.
G10 D3 R.25     ; Sets tool diameter offset #3 to .25 in the offset lib.
G10 D5 R.5       ; sets tool diameter #5 to 0.5” in the offset library.

Centroid G10 Tool Offset Settings – CNC Lathe

G10 P5 Z-1.1 ; Sets tool #5 z offset to -1.1 in the Offset Library
G10 P5 X-1.3 ; Sets tool #5 x offset to -1.3 in the Offset Library
G10 P5 R.25  ; Sets tool #5 nose radius to .25 in the Offset Library
G10 P5 Q3  ; Sets tool #5 nose vector to 3 in the Offset Library

Centroid G10 – Parameter Setting

Multiple parameters can be set with Centroid G10 G code

Examples:

G10 P73 R.05 ; Sets the peck drilling retract amount to .05
G10 P83 R.05 ; Sets the deep drill rapid down clearance to .05
G10 P81 R15  ; Sets G81 to use M15 instead of Z movement

Example

G10 P83 R.05   ; set clearance to .05"
G83 X0 Y0 R.1 Z-2 Q.5  ; drill 2" deep hole in 0.5" steps
G80     ; cancel canned cycle

Example

G73 is the peck drilling cycle.  The hole is drilled in a series of moves: down a distance Q at a given feedrate, up the retract distance at the rapid rate, and then down again at the given feedrate.  The retract amount is set with G10 as shown in the example below.

G90                         ; Absolute positioning
G01 X3.00 Y1.50 Z.5         ; G01 mode before canned cycle
G98                         ; Set for initial point return
G10 P73 R.1                 ; Sets the retract amount to .1
G73 X3.250 Y1.75 Z-.650 R.1 Q0.325 F3 ; Peck drill at X3.25 Y1.75
X4.5 Y3.5                   ; Peck drill at X4.5 Y3.5
G80                         ; Cancel canned cycle, return to G01
