Programming technological functions (cycles)
8.2 Milling
Parameter Description
Machining The following machining operations can be selected:
∇ (roughing)
•
∇∇∇ (finishing)
•
Direction Same direction of machining
•
•
Alternating direction of machining
•
•
The positions refer to the reference point:
Corner point 1X
X0
Y0 Corner point 1Y
Z0 Height of blank
X1 Corner point 2X (abs) or corner point 2X in relation to X0 (inc)
Y1 Corner point 2Y (abs) or corner point 2Y in relation to Y0 (inc)
Z1 Height of blank (abs) or height of blank in relation to Z0 (inc)
DXY Maximum plane infeed
Alternately, you can specify the plane infeed in %, as a ratio → plane infeed (mm) to the
milling cutter diameter (mm).
DZ Maximum depth infeed – (for roughing only)
UZ Finishing allowance, depth
Note
The same finishing allowance must be entered for both roughing and finishing. The finishing
allowance is used to position the tool for retraction.

Rectangular pocket (POCKET3)

Function
You can mill any rectangular pocket with the "rectangular pocket milling" function.
The following machining variants are available:
● Mill rectangular pocket from solid material.
● Pre-drill rectangular pocket in the center first if, for example, the milling cutter does not
● Machine pre-machined rectangular pocket (see "Solid machining" parameter).
Depending on the dimensions of the rectangular pocket in the workpiece drawing, you can
select a corresponding reference point for the rectangular pocket.
