Creating a Workpiece

In the Configuration mode, on the Tightening Positions page, in the Tightening Positions list cancel the selection for all the existing elements. Then, select the Add Workpiece button at the upper-left corner.
A Workpiece pop-up window opens.

In the Workpiece tab, enter and select the workpiece parameters:

• ID: enters the unique identifier string of the group.
  All IDs must be globally unique, so that no other group or position may have the same ID.

• Order: selects the tightening order inside the group, which can be Forced Order or Free Order.

  • Free Order: the operator is free to choose the tightening sequence (or order) of the positions.
    Visual indication is given when the tool is in one of the specified tightening positions.

  • Forced Order: the operator is not free to choose the tightening sequence (or order) of the positions.
    The operator must follow the sequence which is defined by the ordering of the positions in ILG software – from top to bottom. Operator guidance gives a blue position indicator at the specified tightening position.

Within groups with a defined order, it is possible to create a group with another order. The program changes the order as soon as the corresponding subgroup has been selected.

Once the operator starts a tightening within a given group, all elements (tightenings and subgroups) of this group must be finished before moving on to another group of the same hierarchy level.

• Type: the type is Workpiece by default. It is not editable.

• Loosening: defines in which positions the ILG software allows the operator to perform loosening.
  Select the necessary loosening setting.

  • Forbidden: does not allow loosening at all.

  • Valid_positions: allows loosening in all positions.

  • Enabled_positions: allows loosening in all enabled positions.

  • Worked_on_positions: allows loosening in all positions, which have been worked on (OK or NOK).

  • Unsuccessful_positions: allows loosening in all positions with a NOK tightening result.

  • Last_position: allows loosening in the last position. If the last position has been loosened, it changes to the previous position, which thus allows loosening in reverse tightening order.

• Keep tool running: controls if the tool that started in a valid tightening position is still enabled if the operator moves the tool outside of the position during the tightening.
  We recommend to select false. Select true only for very special applications.

• Retries: selects how many retries are allowed for tightening positions.

• Bypass a NOK: selects if a tightening position can be bypassed.

• Tools: assigns the necessary tool to the Workpieces.

In the Projections tab, it is possible to add, edit and delete projections with the buttons in the upper-left corner. The parameters that are entered and selected are:

• Projection type: Sets the projection type to be a shape (arrow, circle/arc, rectangle/square), a tightening result, error and warnings, IDs, loadings or a text string.

• Relative: Sets the projection to be on the workpiece or to be on the bolts.

• Radius: Sets the radius of the projection in mm.

• Offset: Sets the distance to the projected cross in mm.

In the Advanced tab, enter and select the advanced parameters:

• Workflow options (optional)

  • Require effective loosening: if true is selected, loosening is only counted if the tool had a minimum torque during loosening.

  • Geometry condition: enables conditional segments in the geometry. In the Setup mode, on the Tools page, on the Geometry tab, the condition can be called when creating a geometry model or a spindle geometry.

  • Part Target Id: enables dynamic part target referencing.

  • Position Number: Start Bit Offset / Digit Count: specifies the start bit and how many digits that will be used. This is an alternative to Input Groups.

  • Use Tool Orientation: adds an Orientation tab in the Position settings where the Tool Direction Vector and the Enabling/Disabling Angle can be set. Default values are set for the Tool Direction Vector after the function teach is used.

  • PSet after done: after the workpiece is finished the selected Pset will be set on the controller.

  • Delay on enter [ms]: delays the tool that enters a workpiece volume by ms.

  • Delay on leave [ms]: delays the tool that leaves a workpiece volume by ms.

• Referencing (optional)

  • Reference position 1-3: enter the IDs of up to 3 reference positions for workpiece referencing.
    For more information about referencing strategy, see the paragraph Compensation for Variable Workpiece Location: Referencing Strategy.

  • 2P Referencing Axis: selects the rotation axis, around which the workpiece is rotated. Only used if 2-point referencing is used.

At the lower-right corner of the Workpiece pop-up window, select Save.
