Descriere

Instrumentul Hole găurește una sau mai multe găuri dintr-o schiță selectată. Pot fi setați mai mulți parametri, cum ar fi filetarea și mărimea, potrivirea, tipul orificiilor (locaș cap de șurub conic, cilindric, gaură dreaptă) și multe altele.

The centers of the circles and arcs are used to position the holes, but please note that their radii are not taken into account. The generated holes will be identical even if the radii vary.

Countersunk (to the left) and counterbored (to the right) holes cross section.

Cum se folosește

  1. Apăsați butonul Hole .
  2. If an existing unused sketch is found, it will be automatically be used. If more than one sketch is found, a Select feature panel appears to make a selection. Alternatively, a sketch can be selected before launching the Hole command.
  3. Define the Hole parameters. See Options.
  4. Apăsați tasta OK.

Opţiuni

Depending on which selection is made, some fields will activate or stay disabled.

Profile and Placement

Circles and arcs
Points, circles and arcs (default)
Points
  • Profile: if set to None, no threading info is defined. ISO and UTS thread profiles enable the Direction, Size, Fit and Class fields.
  • Threaded: check will add threading data to the Hole feature and the hole minor diameter is used. If left unchecked, the hole is considered non-threaded, and the nominal major diameter with defined Fit is chosen.
  • Direction: sets the thread direction (Right Hand or Left hand) if Threaded is checked.
  • Size: Sets the thread size. Requires Profile to be set to one of the ISO or UTS profiles.
  • Fit: defines standard or close fit for threaded profiles.
  • Class: defines the tolerance class.
  • Diameter: defines the hole diameter if the Profile was set to None.
  • Depth: depth of the hole from the sketch plane. Dimension enables a field to type a value. Through All will cut the hole through the whole Body.

Hole

If set to None, no threading info is defined, and the diameter needs to be set manually.
When set to a supported standard the diameter and other parameters can be set automatically.
If checked, the provided diameter will be the recommended drill size for post-processing with a cutting tap.
If unchecked, the diameter is set according to Clearance to pass-through a thread without contact.
If checked a real thread is modeled. This consumes much computing power and is usually not used for models, except for display purposes or sometimes for 3D prints. If it is used, it is advised to check it as one of the last actions done to the model, because it will increase recomputation time significantly.
If checked, a thread texture is displayed without modeling the thread geometry. This is useful for visualizing threaded holes while avoiding the recomputation cost and file size increase of Model Thread. Cosmetic Thread and Model Thread are mutually exclusive.
Sets the thread direction as Right Hand or Left hand.
Sets the thread size. Requires Profile to not be None
Determines the distance from the thread crest to the side of the hole. Can be understood as how tight a bolt will pass-through.
For ISO threads the diameters are according to the ISO 273 standard
For UTS they are calculated using a rule of thumb because there is no norm defining them.
Dimension: Enables a field to enter a value.
Through All: Will cut the hole through the whole Body
To reduce the file size, do not use Through All if Model Thread is checked, specify a minimal depth instead.

Depth type

Găurirea

  • Type: sets type of hole cut: None is a straight hole; other types are Counterbore, Countersink, Cheesehead, Countersink socket screw and Cap screw.
  • Diameter: sets the major diameter for all hole cut types except None. Value is non-editable if a thread profile was selected in Profile.
  • Depth: depth of the hole cut type from the sketch plane. Value is non-editable if a thread profile was selected in Profile.
  • Countersink angle: angle of the conical hole cut. Value is non-editable if a thread profile was selected in Profile.

Drill point

  • Type: definește capătul orificiului dacă "Adâncimea" este setată la "Dimensiunea". Flat produce un fund plat; Unghiul stabilește un capăt conic.

Diverse

  • Tapered: sets a taper angle to the hole. Value is calculated from the sketch plane normal. 90 degrees sets a straight hole. A value under 90 generates a smaller hole radius at the bottom; a value over 90 enlarges the hole radius at the bottom.

Operation

Sets the boolean operation used to combine the hole with the base solid. introduced in 26.3

Proprietăți

Much of the Data properties are the same as those shown in Options.

  • DateLabel: name given to the object, this name can be changed at convenience.
  • DateReversed: true or false. Reverses extrusion direction.
  • DateRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.


Start

Limite

  • The selected sketch must contain one or more circle(s). The radius of the circle(s) inside the sketch is not taken into account. The generated holes will be identical even if the circles in the sketch have varying radii.
  • By default, the hole feature extrudes below the sketch plane. If the solid lies on the XY_Plane, and the hole sketch is attached to the XY_Plane, it will try to extrude away from the solid and seemingly produce no result. In such a case, the Reversed property needs to be manually set to true; otherwise the sketch needs to be mapped to the bottom face of the solid.

Cut Type Definitions

Cut types (screw-types) are defined in json files. There is a set of files distributed with FreeCAD, but users can create their own definitions. Files are searched in <UserAppDataDir>/PartDesign/Hole. The UserAppDataDir can be found by typing App.getUserAppDataDir() in the Python Console.

The file should contain:

Example:

{
    "name": "DIN 7984",
    "cut_type": "counterbore",
    "thread_type": "metric",
    "data": [
        { "thread": "M2",   "diameter":  4.3, "depth":  1.6 },
        { "thread": "M2.5", "diameter":  5.0, "depth":  2.0 },
        
    ]
}
