N0 G50 X50.0 Z70.0 Set the workpiece origin on the left end Thread processing example: As shown in Figure b, the thread pitch L=3.5mm, the thread height=2mm, the spindle speed N=514r/min, δ1=2mm, δ2=lmm, two turnings, each turning depth is lmm. Δ1, δ2: the cut-in amount and cut-out amount. Α: taper angle of taper thread, if α is zero, it is straight thread L: Thread lead, when machining taper threads, the one with the larger thread lead in the X and Z directions The meaning of each parameter is as follows: The parameters to be determined before using the G32 command are shown in Figure a. X(U) and Z(W) in the command are the coordinates of the thread end point, and F is the thread lead. The processing method is divided into single-stroke thread cutting, simple thread cutting cycle and thread cutting compound cycle. The CNC lathe can process straight threads, tapered threads, and end threads, as shown in the figure.
