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)

Z of the blank that will be
Imported.

The CYLINDER_POSITION curve must be contained into
the –DM-clamps layer.

loading (thanks to the postprocessor’s customization
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.

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".

“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)

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.

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)

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").
