Drilling operation processes

Select this counter sinking configuration mode and fill in the corresponding values:

• Diameter - Angle

• Diameter - Depth

• Angle - Depth

• Diameter - Angle - Depth

For the angle, two angle configuration modes can be chosen:

• Opening angle:it is the total angle of the counter sinking.

• Angle with the entry face: its is the angle between the counter sinking and the face to drill.

Give the diameter of the spot facing, its depth and a bottom radius if needed.

Standard:

Select the screw spot facing standard you wish to use. The list proposes the screw spot facing standards available in the referenced projects or libraries

Nominal diameter:

This list displays the diameters available in the selected standard. The values displayed with a white background (instead of green) are the dimensions defined as "Occasional use" in the document of this standard.

Description:

Defined in the standard document

Head type:

Specify the head type to use. Facing diameter will change according of this type (cylindrical or hexagon).

Diameter:

Display the spot facing diameter that will be used (this value coming from the selected standard document).

Forced diameter:

Possibility to impose a value other than the one coming from the standard. Possibility to use parameter with 0mm as value, in this case we use the standard value as default and if the parameter is modified with value bigger than 0mm then we will use this one.

Depth:

Specify the facing depth.

Diameter:

Provide the diameter of the hole.

Depth:

Select the depth definition mode:

For the blind hole, you can use three modes to determine the depth of the hole:

Conicity:

Allows to define if the hole is conical and in this case, its angle of conicity. By default, this option is unchecked.

Bottom type:

Next, define the type of end:

Total depth:

This option allows to indicate that the depth is at point.

Standard:

Select the threading standard you wish to use. The list proposes the threading standards available in the referenced projects or libraries

Model:

This option allows to create the actual tapping shape for 3D printing.

Here's how to make a user threading standard compatible with 3D modeling:

• In a 2D model document, draw internal and external thread profiles (in 2 different sketches).

• Provide the Threading profile function to this 2D model document and fill publications (profiles, positioning frames, diameters ...).

• Into your threading standard document, select your 2D model document in the Thread profile field.

Tapping:

• Nominal diameter: this list displays the diameters available in the selected standard. The values displayed with a white background (instead of green) are the dimensions defined as "Occasional use" in the document of this standard.

• Pitch: defined in the document of the standard or enter it if Standard is unchecked.

• Description: defined in the standard document or enter it if Standard is unchecked.

• Complete tapping: check this option to have a complete tapping of the hole.

• Depth: if the Complete tapping option is unchecked, specify a tapping depth.

• Rounding:  when the Complete tapping option is unchecked or when the Blind option of the hole is selected, you can round the value of the depth with an accuracy and a rounding mode (Nearest value, Inferior value and superior value).

Hole:

• Diameter: Corresponds to the drilling diameter. This value is defined in the standard based on the nominal diameter.

• Type:

• • Through all: the hole crosses all the thicknesses of the shape.

  • Through:  the hole crosses the first thickness of the shape.

  • Blind: you can manually define the depth of the hole and the bottom type (cone, flat or sphere).

  • • Rounding: See above

  • Up to point: you can manually define the depth of the hole by selecting a point.

  • Up to plane: you can manually define the depth of the hole by selecting a plane.

  • Up to surface: you can manually define the depth of the hole by selecting a surface.

• Bottom type:

Next, define the type of end:

• Total depth:

This option allows to indicate that the depth is at point.

Advanced:

• Number of starting threads: 1 by default. You can specify a different number of starting threads.

• Left-hand thread: you can inverse the threading direction by checking this check box.

• Taper: the tapping hole can be conical by checking this option. in this case, enter its angle. If the tapping is conical, it is possible to have a conical hole too by checking this option.

Standard:

Select the clearance hole standard you wish to use. The list proposes the clearance hole standards available in the referenced projects or libraries

Nominal diameter:

This list displays the diameters available in the selected standard. The values displayed on a white background (instead of green) are the dimensions defined as "Occasional use" in the document of this standard.

Description:

Defined in the document of the standard.

Head type:

Defines the type clearance hole (Fine, Medium or Large). This determines the oversizing of the clearance hole in relation to the nominal diameter of the threading.

Diameter:

Display the clearance hole diameter that will be used (this value coming from the selected standard document).

Forced diameter:

Possibility to impose a value other than the one coming from the standard. Possibility to use parameter with 0mm as value, in this case we use the standard value as default and if the parameter is modified with value bigger than 0mm then we will use this one.

Depth:

• Through all: In this mode, the hole crosses all the thicknesses of the shape.

• Through: In this mode, the hole crosses the first thickness of the shape.

• Blind: In this mode, you can manually define the depth of the hole and the bottom type (cone, flat or sphere).

• Up to point: In this mode, you can manually define the depth of the hole by selecting a point.

• Up to plane: In this mode, you can manually define the depth of the hole by selecting a plane.

• Up to surface: In this mode, you can manually define the depth of the hole by selecting a surface.
