4.2.1. Part setup
Material shape, diameter and length, variable face-off distance
Material shape
Round material:
• outer bar diameter
Hex / square material:
• diameter across flats
• diameter across corners
• Front rest guiding element
• When the material is profiled, the bar feed system will try several times (for 2 minutes), to position
the bar inside the clamping device of the lathe. The accuracy of the positioning is also assured by
a positioning procedure designed specifically for profiled bars.
Total part feed out length
The feed-out length (Lt) includes the part length (Lp), the cut-off tool width (C) and the face-off length (not
represented on the picture, depending on the program).
Variable face-off distance
Distance from the face of the lathe’s chuck to the cutting position.
