Table
Thread table selection:
• without
• ISO metric
• Whitworth BSW
• Whitworth BSP
• UNC
Selection - (not for
table "Without")
Data, table value, e.g. M10, M12, M14, ...
P
Select the thread pitch / turns for table "without" or specify the thread pitch/turns
corresponding to the selection in the thread table:
• Thread pitch in mm/revolution
• Thread pitch in inch/revolution
• Thread turns per inch
• Thread pitch in MODULUS
mm/rev
in/rev
turns/"
MODULUS
G Change in thread pitch per revolution - (only for P = mm/rev or in/rev)
G = 0: The thread pitch P does not change.
G > 0: The thread pitch P increases by the value G per revolution.
G < 0: The thread pitch P decreases by the value G per revolution.
If the start and end pitch of the thread are known, the pitch change to be
programmed can be calculated as follows:
|P

The meanings are as follows:
P
e
: End pitch of thread [mm/rev]
P
a
: Start pitch of thread [mm/rev]
Z
1
: Thread length [mm]
A larger pitch results in a larger distance between the thread turns on the
workpiece.
