G24 Straight Facing
The format for the G24 straight facing cycle is:
G24X__ Z__;
Where: Is :
X__ the lengthofgrind along theX-axi s. Inincrementalmode, specifytheamountof
feedacrossthepart. In absolutemode,specify the coordinate position ofthe
end pointof the grinding/dressingstroke. X canbeprogrammed as a diameteror
radiusvalue.
Z__ the grinding/dressingdepth fortheZ-axis. In incremental mode,specifythe
amountof infeed. Inabsolute mode, specifythecoordinateposition atthe
desiredgrinding/dressingdepth.
After the control executes the G24 block, the control re-executes the cycle
for any following block that commands axis motion until the cycle is
canceled. The values of the axis words in the following block replace the
values of the parameters specified in the original G24 block and the cycle
is re-executed using these new values.
