If the minus value is commanded for the shift amount Q, the algebraic mark (-) is ignored.
The shift direction is selected from +X, -X, +Y and -Y set by the parameter 1 in advance.
The shift direction can be selected only from the above four. Therefore, the tool should be
mounted so that the tool nose faces in one of the specified direction when the spindle
orientation executes.
G99 (R point level return) is unused.
When V is omitted, 0° is considered to be commanded.
