Drilling hole
Menu access: Shape | Drilling
Description:
Allows you to position different type of drilling on solid shapes.
General philosophy:
Select the face to drill.
Select a face or edge as the alignment reference.
Enter the offset value distance defining the center of drilling from the first reference previously selected.
Select a face or edge as the alignment reference (must be non-parallel to the previous one).
Enter the offset value distance defining the center of drilling from the second reference previously selected.
Choose the drilling type to apply on this position.
A dialog box let you choose the type of drilling to apply or if you want to create your own drilling feature.
Available option(s):
The COORDINATE
SYSTEM button
allows you to select (or create) a coordinate system to locate your drilling.
The question from 2 to 5 will not bee asked. We using this option, the
drilling is always made along -Z axis of the selected coordinate system.
The DEFINE
MODEL button
allows you to create you owns drilling models with specific operations
and default values.
The option Model= USER or GROUP allows you to choose if the new model must be saved in the group configuration (...\Group\) or in the user configuration (...\Missler\Config).
The bitmap used for the model preview must be in the "Group" folder for the group models and in the "Config" folder for the user models.
The drop down list Frame=
allows
you to choose three types of coordinates system for the "Dynamic"
mode:
CONSTRAINT: for a planar face with linear edges.
RADIAL: for a planar face with circular edges.
POLAR: for a cylindrical face.
The option Mode=
NON DYNAMIC or
DYNAMIC
allows
you to use the usual way of creating a coordinate system (selecting edges
and setting a distance from them) or the dynamic way.
The COPY
PROPAGATION button
allows you to define at the same time an operation propagation to apply
on your drilling.
You cannot copy single
tapping or single c-sinking because these operations need the cylindric
reference face of an existing hole.
The mode "through
one" with a part with several thickness is only supported by the
following propagations: linear, matrix, rectangular, circular translation,
circular (if the reference face is planar and if the direction of the
propagation axis is the same as the direction of the drill axis), on curve
(if the curve is planar).
The other propagation modes cannot automatically find the needed depth to through only once.
The following options are options
common to all the models of drillings:
|
|
Axis: create a axis curve on the drilling. Drilling origin: the depth of drilling can be measured from the reference face or from the reference coordinate system of the drilling. That can prove to be useful if you created a drilling on a coordinate system which is not on the reference face. Component designation: get the designation of the component who have done the drilling, this designation will be used in the drills table. This field can also be entered manually. Designation: you can give a designation to the drilling, it will be displayed in the symbolic tree. Machining process: In the case of a specific drilling, you can associate a machining process to him. |
These two last options are useful for the TopSolid/CAM module which can use this information then. You can add new processes of machining in the list, in a manual way in the file top.mac (folder..\Missler\Config). However, the TopSolid/CAM module enables you to enrich this list of machining process by a more automatic way.
Specific point(s):
When the option "Through
one" is selected, to calculate the depth of drilling, TopSolid
makes a research of the intersections of the circle projected (with a
diameter equivalent to the drilling diameter) on the face opposed to the
drilling face, if a discontinuity is detected in the circle projected,
the drilling through one could not be done and the option "Through all" is automatically selected.
Example :
|
|
|
|
In this case, there's no discontinuity on the projected circle, drilling through one could be done normally. |
|
|
|
|
|
In this case, there's some discontinuity on the projected circle, drilling through one could not be done normally and a drilling of the type "Through all" will be done. It will then be necessary to choose the "Blind" option and to specify a depth. |

Specific application example(s) :
Drilling of a cylindrical face: A coordinate system (radial coordinate system on face or coordinate system on face) is required to drill this type of face, the drilling function allows to directly create a radial coordinate system on face.
