Point to Point

The Point to Point dialog box appears when you select Point to Point. This dialog box contains controls for:

Motions Parameters

Properties
Edits the motion selected in the dialog box.
Delete
Deletes the motion selected in the dialog box.
and
Changes the rank of the motion selected in the dialog box.
Goto Point
Creates a tool motion defined by the point the tool tip has to reach. Geometry is selected as follows:
  • Direct selection on the part (points, vertices, and so on)
  • Direct indication in a pre-selected surface. Only selection done within the topological limits of the surface are taken into account.
  • Indication of points to be projected onto a user-defined indication plane. This indication plane is considered as infinite (it has no topological limits). This allows point indication outside the part boundaries. It is a temporary element used as an aid for selection. It is not saved after operation edition.
Go Delta
Creates a tool motion defined by a displacement relative to a previous Goto Point, Goto Position or Go Delta motion location. Types of Go Delta motion are defined from the dialog box that appears, and are as follows:
  • Components: relative motion defined by DX , DY, and DZ displacements from previous motion location.

    Specifies DX , DY, and DZ displacements.

  • Along X axis: relative motion along X axis (current axis system) on a specified Distance, from previous motion location.

    Specifies DX displacement.

  • Along Y axis: relative motion along Y axis (current axis system) on a specified Distance, from previous motion location.

    Specifies DY displacement.

  • Parallel to Line: relative motion on a specified Distance, parallel to a selected Line, from previous motion location.

    Specifies Offset and Local feedrate.

  • Normal to Line: relative motion on a specified Distance, normal to a selected Line, from previous motion location. The tool motion is done in a plane perpendicular to the tool axis.

    Specifies Offset and Local feedrate.

  • Angle to Line: relative motion on a specified Distance, along a line computed from defined Angle and Line. The tool motion is done in a plane perpendicular to the tool axis.

    Specifies Angle, Offset, and Local feedrate.

Goto Position
A tool motion is defined by positioning the tool in contact with a part element, a drive element, and possibly a check element, while taking To / On / Past conditions into account. The tool axis for this motion is perpendicular to the selected part. It is defined from the dialog box that appears:
Part
Select part element in the 3DEXPERIENCE platform.
Part thickness
Specifies part thickness.
Position on drive
Specifies To / On / Past positioning conditions.
Offset on drive/check
Specifies drive and check offsets.
Position on Check
Specifies To / On / Past / Tgt positioning conditions.
PP words
Insert PP words.

Strategy Parameters



First compensation
Specifies the tool corrector identifier to be used in the operation. The corrector type (P1, P2, and P3, for example), corrector identifier, and corrector number are defined on the tool. When the NC data source is generated, the corrector number is generated using specific parameters.
Machining tolerance
Specifies the maximum allowed distance between the theoretical and computed tool path.
Offset along tool axis
Defines an offset along the tool axis for all positions of the tool path (it is taken into account for all the positions of the operation).

User Parameters

See Adding a User Parameter

Tools

All milling and drilling tools is used in this type of operation.

See Assigning a Tool Element to a Machining Operation

Feedrates and Speeds Parameters

Transition
You can locally set the feedrate for a transition path to a machining operation B from a machining operation A or from a tool change activity. This is done by selecting the Transition check box in the Machining Operation dialog box for operation B.

For more information, please refer to the Setting a Transition Feedrate.

Spindle output
This check box manage output of the SPINDL instruction in the generated NC data file:
  • If the check box is selected, the instruction is generated.
  • Otherwise, it is not generated.

Note:

The spindle speed is defined in linear (length per minute) or angular (length per revolution) units.

  • Angular: length in revolutions per minute and unit is set to mm_turn.
  • Linear: length in feed per minute and unit is set to mm_mn.

Quality
The feed and speed values are computed according to the Quality setting on the operation.
Compute
Feeds and speeds of the operation is updated according to tooling feeds and speeds by clicking the Compute button located in the Feeds and Speeds tab of the operation.

Feeds and speeds of the operation is updated automatically according to tooling data and the rough or finish quality of the operation. This is described in Updating Feeds and Speeds in Machining Operations.

NC Macros

You can define transition paths in your machining operations by means of NC macros:

  • Approach: to approach the operation start point,
  • Retract: to retract from the operation end point,

These transition paths are built from elementary motions.

The proposed macro mode are:

  • None
  • Build by user

For more information, please refer to the Defining Macros.

The following macros are available in a Point to Point operation for Build by user macro mode:

  • Axial motion
  • PP word
  • Axial motion to a plane
  • Distance along a line motion
