Input
• Complete
S / V
Spindle speed or constant cut-
ting rate
rpm
m/min
P
• Thread pitch in mm/revolution
• Thread pitch in inch/revolution
• Thread turns per inch
• Thread pitch in MODULUS

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 pro-
grammed can be calculated as follows:
|P
e

- P

G = ----------------- [mm/rev2]
2 * Z

The meanings are as follows:
P
e
: End pitch of thread [mm/rev]
P: 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 work-
mm/rev

Machining
• ∇ (roughing)
• ∇∇∇ (finishing)
• ∇ + ∇∇∇ (roughing and finishing)
Infeed (only for ∇ and ∇
+ ∇∇∇)
• Linear:
Infeed with constant cutting depth
• Degressive:
Infeed with constant cutting cross-section
