PREMILLED MANAGEMENT (.BLK)

EQUIPMENT (.EQP)

## 4. Diapositiva 4

The equipment defines:
How many “premilled cylinders” is possible to insert in
the equipment
“premilled cylinders” positioning
In order to manage that, the equipment must contains the curve
(or more) named CYLINDER_POSITION
In case the equipment allows to use more “premilled cylinders”,
in each position will be necessary the related
CYLINDER_POSITION1 / CYLINDER_POSITION2 /
CYLINDER_POSITION3 curves…
(see following pictures)

## 7. Diapositiva 7

IMPORTANT
The CYLINDER_POSITION curve must be placed
in the center, at median Z of the blank that will be
Imported.
The CYLINDER_POSITION curve must be contained into
the –DM-clamps layer.

## 8. Diapositiva 8

IMPORTANT
After the cam file creation and the following automatic
code LOADEQP), the blank’s “hook” will be applied on the
CYLINDER_POSITION curve’s end.
Take care to the curve’s direction!
If that entity has an opposite direction than the requested one,
the imported blank will be placed on the opposite side of the
curve, that is on a wrong point!
No matter the curve’s length, important is its ending point.

## 9. Diapositiva 9

IMPORTANT
The CYLINDER_POSITION curve also could have an “L” shape**.
In that way, in addition to define the “premilled cylinder”
positioning, it will be even possible to properly orientate an
abutment having an interface with at least one planar surface
(antirotational) – for instance an hexagonal interface – in order
to align an interface’s planar surface to the “L”
CYLINDER_POSITION curve.
** Geometrically, the ends of the two segments of the "L" define
three points ... and these three points go to define just one
plane (having only one defined and unambiguous angle). For
that reason the planar face of the interface will be well aligned
according to the same angle of the curve "L".

LAYERS and CURVES
The abutments premilled cylinders must be imported by the
“blank import” command
, after the stl abutment import
into a cam file already having an equipment that contains the
positioning CYLINDER_POSITION curve.
The “.blk” file must contains:
cylinder surfaces (layer -DM-O1 )
interface’s protection surfaces (layer -DM-Y )
necessary curves for the coupling with the equipment and with
the abutment to contain; curve names must be
CYLINDER_ORIGIN and PRE_MILLED_POSITION (layer-DM-O1)
(see following pictures)

## 16. Diapositiva 16

CYLINDER_ORIGIN e PRE_MILLED_POSITION
For both these curves, the “hook” is corresponding to their ends.
The CYLINDER_ORIGIN curve is used to place the object at the
end of the CYLINDER_POSITION curve, that is located on the
equipment (that must be imported into the working file before
the abutment import and before the cylinder stock import).
The PRE_MILLED_POSITION curve is used to reposition the
abutment that has been imported. The end more “external” of
the abutment hole axis (or another cylindrical part) is positioned
at the end of this curve.

## 17. Diapositiva 17

PRE_MILLED_PHASE
Previous picture also show an additional curve (not mandatory),
it’s the PRE_MILLED_PHASE curve.
It allows to orient the “timing” of the imported abutment in
order to correspond to the “cylinder” timing.
If this curve is not there, the “timing” executed during the
abutment import remains applied, otherwise a correspondence
between the shape of curve PRE_MILLED_PHASE (whose
orientation is not important) and the shape of imported
abutment is searched.
The PRE_MILLED_PHASE curve must represents a portion of the
abutment geometry, enough to determine the unequivocal
correspondence to the shape of the imported abutment.
(see following pictures)

## 19. Diapositiva 19

IMPORTANT
The PRE_MILLED_PHASE curve must be positioned in same area
in which the corresponding part to be coupled (it’s into stl file to
import) will be placed, in order to be able to determine the
unambiguous correspondence with the shape of the imported
abutment.
If that curve were to be placed in a not correct point, a
"matching error" message will appears during the blank import
(cylinder premilled. "blk").
