4. THREAD CUTTING
NC FUNCTION
73
Continuous thread cutting in which thread cutting command block is
continuously commanded is available. As it is controlled so that the
spindle synchronism shift (occurred when shifting from one block to
another) is kept to a minimum, special threads like threads which leads
or shape change during the cycle can also be cut.

Using the G35 and G36 commands, a circular thread, having the specified
lead in the direction of the major axis, can be machined.
L
Circular thread
G35 : Clockwise circular threading command
G36 : Counterclockwise circular threading command
X (U) : Specify the arc end point (in the same way as for G02,
G03).
Z (W)
I, K : Specify the arc center relative to the start point, using
relative coordinates (in the same way as for G02, G03).
R : Specify the arc radius.
F : Specify the lead in the direction of the major axis.
Q : Specify the shift of the threading start angle (0 to 360°
in units of 0.001°)
