simultaneously
X: absolute coordinates of center point in X direction; U: the difference of the absolute
coordinates of the center point and start point in X direction;
Z: absolute coordinates of center point in Z direction; W: the difference of the absolute
coordinates of the center point and start point in Z direction.
Process of instruction action (see the figure below):
(1) Move to center point from the start point simultaneously at independent fast
moving speed (point A → point B).
(2) When the two axes reach the center point, move to the mechanical home from the
center point simultaneously at independent fast moving speed (point B →point
R).
(3) If U and W are 0, return to the machine tool home directly, e.g. G28 U0 W0, the
system returns to the reference point directly, and doesn’t pass through the
center point (point A → point R).

3.3. Thread cutting
3.3.1. Thread cutting instruction G32
Instruction format: G32 X(U)__Z(W)__ F__P__D__V__;
X(U): thread X axis end point coordinates or increment value
Z(W): thread Z axis end point coordinates or increment value
F: metric thread pitch (0.001~500 mm), it is the movement of the long axis when
the principal axis rotates a circle, maintain valid after F instruction value is
executed, until the F instruction word of specified thread pitch is executed again.
P: thread cutting acceleration pitch, the unit is mm, unsigned, the acceleration
length of the long axis during thread cutting; if the program doesn’t specify the P
value, the system calls parameter #109 automatically for calculation; if X is long
axis, P is the radius.
D: thread cutting deceleration pitch, the unit is mm, unsigned, the deceleration
length of the long axis during thread cutting; if the program doesn’t specify the D
value, the system calls parameter #110 automatically for calculation; if X is long
axis, D is the radius.
V: pitch cutting back amount, the unit is mm, signed; the sign relates to the back
direction; it is the back length of the short axis during thread cutting; if the
program doesn’t specify the V value, the system calls parameter #111
