Programming pockets with 3D profiles
Pocket ID number. (3D POCKET)
It is possible to have several 3D pockets. The CNC associates with each 3D pocket all its data (surface
profile, depth profile, machining conditions, etc.)
Surface profile or profile in the X,Y plane. Profile (P. XY).
It must indicate the contour or contours of the possible islands besides the outside contour of the pocket.
Depth profile corresponding to the profile defined first. Profile (P. Z1)
It usually corresponds to the outside contour of the pocket.
Depth profile corresponding to the profile defined second . Profile (P. Z2)
It usually corresponds to the contour of the island defined first.
Depth profile corresponding to the profile defined third. Profile (P. Z3)
It usually corresponds to the contour of the island defined second.
Depth profile corresponding to the profile defined fourth. Profile (P. Z4)
It usually corresponds to the contour of the island defined third.
Once all the profiles have been defined, the 3D pocket configuration must be validated. To do so, place
the cursor over the icon and press
The cycle will show the icon.
The machining operation in Z is defined by means of:
The coordinate of the safety plane .......... Zs Coordinate of the part surface ..................... Z
Pocket depth ........................................... P Roughing pass in Z .................................... I1
Penetration feedrate in Z ........................ Fz Semi-finishing pass in Z ............................. I2
In the area for roughing data, the following must be defined:
Lateral penetration angle ..........................
β
Milling pass ................................................
∆
In the area for finishing data, the following must be defined:
Tool tip radius ......................................... R Finishing stock on walls ...............................
δ
Finishing pass ....................................... (e)
Direction of the finishing passes on the walls
Notes: The pocket configuration program and the profile programs can also be accessed in the "M" mode
since the CNC stores them internally as:
P995xxx 3D pocket configuration
P998xxx The XY plane profiles in 2D and 3D pockets
P996xxx Depth profiles in 3D pockets
3.5.1 DATA DEFINITION
Machining conditions in Z (Zs, Z, P, Fz, I, I1, I2)
The machining conditions must be defined one by one.
To define the values (P, Fz, I, I1, I2), 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.
