Path/time-related feed interpolation (G193/G293)

Notice

notice

Path-related feed interpolation is only effective in combination with linear slope (#SLOPE [TYPE=STEP]) or HSC slope (#SLOPE [TYPE=HSC]).

Time-related feed interpolation is only effective in combination with linear slope (#SLOPE [TYPE=STEP]).

G193                               Path-related feed interpolation                                       (non-modal)

G293                               Time-related feed interpolation                                        (non-modal)

When G193/G293 is selected, the feedrate between the initial and the programmed end velocity is linearly interpolated.

Notice

notice

It is not permitted to program G193 with G293, G08 or G09 in the same NC block.

Programing Example

prg_example

Path-related feed interpolation with (G193)

N10 G01   X500 F1000

N20 G193  X900 F400

N30 X1000 F400

At block transition N10/N20, path-related feed interpolation is activated and decelerated linearly to end velocity across the path programmed in N20.

Programing Example

prg_example

Path-related feed interpolation with (G293)

N10 G01   X500  F1000

N20 G293  X900  F400

N30       X1000 F400

Time-related feed interpolation is activated at block transition N10/N20 and linearly decelerated over time to end velocity.
