⌨Format and notes

G75 R_ ;
G75 X(U)_ Z(W)_ P_ (X depth of cut) Q_ (Z travel) R_ F_

The X-direction version of G74. Plunges the groove with pecking in X, and shifting Z widens it

Diagram: G75 (lathe): grooving with pecking in X

Cuts in by P in X each time, retracting a little (R amount) to break chips while grooving. Repeating with Z shifted by Q each time makes a groove wider than the insert.
