Exact stop (G60/G360/G359)

Syntax:

G60

Exact stop

non-modal

... or for exact stop across several blocks:

G360

Selecting exact stop

modal

G359

Deselecting exact stop

modal

G60/G360 allow the exact approach to a target point within the exact stop limits. The feed rate is decreased to zero up to block end and decreases the following error.

The exact stop can be used if edges must be precision-machined or if the target point must be precisely reached in case of direction reversal. The motion is continued to the next position when a parameterisable control window is reached (P-AXIS-00236).

Programing Example

prg_example

Examples of exact stop

N10 G1 F1000 X0 Y0

N20 G1 G60 X10  ( Exact stop for this block end )

N30 G1 X20

N40 G60 Y20     ( Exact stop for this block end )

N50 G1 X30

;...

By analogy, implementation with G360 and G359

N10 G1 F1000 X0 Y0

N20 G1 X10

N30 G360        ( Select exact stop )

N40 G1 Y20

N60 G1 X30

N70 G359        ( Deselect exact stop )

;..

If a G60 is programmed in an NC line without motion information, error ID 20003 is output.
