\par \pard
\par \b0\fs20 The G75 command permits drilling and grooving in the X axis.
\par A chip break cycle is also possible - chip breaking is the same as drilling in pecking stages to limit swarf size.\b\fs24
\par
\par
\par \cf2\fs20 A G75 command is written in the following format :
\par G75 R (1) ;
\par G75 X (U) Z (W) P Q R (2) F ;
\par where,
\par the definitions of R (1) , X (U) , Z (W) , P , Q , R (2) and F are the same as G74.
\par
\par where,
\par R(1) is the peck return amount.
\par X (U) is the diameter of the bore if stepover is used (ie, stepping along the X axis to repeat the peck cycle).
\par Z (W) is the depth of the bore.
\par P is the stepover in the X axis measured in micron's (without sign).
\par Q is the pecking depth in the Z axis measured in micron's (without sign).
\par R (2) is the retract move at the base of the groove.
\par F is the feedrate.\b0
