3.4.1 SURFACE MILLING DATA DEFINITION
Type of surface milling
To select the type of surface milling, place the cursor over this icon and press
Surface to mill (X1, Y1, L, H, E,
α α
)
Define one of the corners of the surface to be milled (X1, Y1), the length (L) and the width (H). The
sign of L and H indicates the orientation with respect to the point X1, Y1.
The X1, Y1 coordinates may be defined by:
a) Entering the value by hand. Key in the desired value and press
b) Assigning the current position of the machine.
Move the axis to the desired point with the handwheel or the JOG keys. The top right window shows
the tool position at all times.
Press so the selected data assumes the value shown in the top right window and press
Once the surface to be milled has been defined, the icon shown at the bottom right (area for roughing
and finishing) allows selecting the corner where it will start milling. Possible values:
The "E" and "
α α
" data are defined one by one. Go to the relevant window, key in the desired value and
press
When programming an "E" value smaller than the tool radius, the CNC mills with an "E" value equal
to the tool radius.
Machining conditions in Z (Zs, Z, P, I, Fz)
They are defined one by one. The Zs and Z values are defined like the starting and end points.
To define the rest of the values (P, I, Fz), place the cursor in the corresponding window, key in the
desired value and press
If the penetration step is programmed with a positive sign (I+), the cycle recalculates the step so allthe
penetrations are the same with a value equal to or smaller than the one programmed.
If it is programmed with a negative sign (I-), the cycle machines with the given step except on the last
one where it machines the rest.
Milling step (
∆ ∆
) and finishing stock (
δδ
z
)
They are defined one by one. Place the cursor in the corresponding window, key in the desired value
and press
