The function must be set up by the machine manufacturer.
(only for ShopTurn)
Machining The following machining operations can be selected:
● ∇ (roughing)
● ∇∇∇ (finishing)
● ∇∇∇ edge (edge finishing)
● Chamfering
The positions refer to the reference point:
X0 (only G code) Reference point X
Y0 (only G code) Reference point Y
Z0 Reference point Z
∅ Diameter of blank spigot
N Number of edges
SW or L Width across flats or edge length
R1 and FS1 Rounding radius or chamfer width
Z1 Multi-edge depth (abs) or depth in relation to Z0 (inc) - (only for ∇, ∇∇∇ and ∇∇∇ edge)
DXY
● Maximum plane infeed
● Maximum plane infeed as a percentage of the milling cutter diameter
DZ Maximum depth infeed – (only for ∇ and ∇∇∇)
UXY Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge).
UZ Depth finishing allowance (only for ∇ and ∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
* Unit of feedrate as programmed before the cycle call
