Parameter Description Unit
αC
(for ShopMill program)
Rotational position for a pole position Degrees
Hirth joint
● Round to the next Hirth joint
● Round up to Hirth joint
● Round down to Hirth joint
Note:
For machines with a Hirth joint
Tool Tool tip when swiveling
● Tracking
The position of the tool tip is maintained during swiveling.
● No tracking
The position of the tool tip is not maintained during swiveling.
Preferred direction (for
ShopMill program)
Preferred direction of the swivel axis for several possible alignments of the machine
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 programmed
can be calculated as follows:
|P

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 workpiece.
