Unit of measure for F with G94, G95
The dimension unit for the F word is determined by G functions:
G94 F as the feedrate inmm/min
Remark:
This unit of measure applies to metric dimensions. According to Section “Metric and inch
dimensioning”, settings with inch dimensioning are also possible.
8.3.11 Exact stop / continuous-path control mode: G9, G60, G64
Functionality
G functions are provided for optimum adaptation to different requirements to set the travers-
ing behavior at the block borders and for block advancing.
Example: For example, you would like to quickly position with the axes or you would like to
machine path contours over multiple blocks.
Programming
G60 ; Exact stop – modally effective
G64 ; Path-control mode
G9 ; Exact stop – non-modal
G601 ; Exact stop fine window
G602 ; Exact stop coarse window
Exact stop G60, G9
If the exact stop function (G60 or G9) is active, the velocity for reaching the exact end posi-
tion at the end of a block is decelerated to zero.
Another modal G group can be used here to set when the traversing movement of this block
is considered ended and the next block is started.
S G601 ; Exact stop window fine
Block advance takes place when all axes have reached the “Exact stop window fine” (va-
lue in the machine data).
S G602 ; Exact stop window fine
Block advance takes place when all axes have reached the “Exact stop window fine” (va-
lue in the machine data).
The selection of the exact stop window has a significant influence on the total time if many
positioning operations are executed. Fine adjustments require more time.
