Fig. 3 Block joint with cutting feed in-position check
In Figs. 2 and 3:
As shown in Fig. 3, the in-position width "Lc" can be set into the servo parameter "#2224
SV024" as the remaining distance (shaded area in Fig. 3) of the previous block when the next
block is started.
The in-position width is designed to reduce the roundness at the workpiece corners to below
the constant value.
To eliminate corner roundness, set the servo parameter "#2224 SV024" to zero and perform an
in-position check or assign the dwell command (G04) between blocks.
