Thread (standard) G34–Geo
G34 defines a simple or an interlinked external or internal thread
(metric ISO fine-pitch thread DIN 13 Series 1). The control
calculates all the required values.
Parameter:
F: Thread pitch
Threads are concatenated by programming several G1/G34 blocks
after each other.
You need to program a linear contour element as a
reference before G34 or in the NC block containing
G34
Machine the thread with G31
