Teaching Process
Prerequisites
During the Teaching process, nominal positions or target coordinates are assigned to the process model in ILG software. This process defines the geometrical model of a workpiece.
After entering the coordinates, ILG software enables tightening in the correct positions of the active workpiece. Thus, it is very important that the Teaching process is run under optimal conditions.
Before running the Teaching process, make sure that:
A real workpiece is in the system; the fastening conditions - workpiece geometry, fasteners, and so on - agree with the conditions in normal production.
The workpiece is optimally positioned in the workspace
The geometry of the tool is completely mapped within ILG software.
The fastening sequence of the components is known and is observed during the Teaching process.
The controller is configured and connected to the ILG software.
Teaching
In ILG software, the Teaching process causes a completely new tightening position along with the new related coordinates.
Three teaching options are possible and works as follows:
Teaching and creating a new workpiece:if no workpiece is selected, the teaching will create a new workpiece with default parameter values (P-Set, Enabling Volume and Disabling Volume).
Teaching a workpiece with no positions previously added: the teaching will add positions with default parameter values (P-Set, Enabling Volume and Disabling Volume).
Teaching a workpiece with positions previously added: the teaching will replace the already existing positions, their coordinates and settings with the default parameters (P-Set, Enabling Volume and Disabling Volume). If the number of positions that are taught are higher that the number that were previously in the workpiece, the teaching will add these additional positions with default parameter values.
The default parameter values for teaching is P-Set=0, Enabling Volume=10 mm shere and Disabling Volume=upscale 10% of enabling volume.
The Teaching process of new workpieces is used for simple process setups, where only 1 workpiece exists. In this case, all the tightening positions are into the only existing workpiece.
If the process has a more complex structure, we recommend to create the workpiece and group structure. Then, perform the Teaching process for the existing groups.
If the Teaching process is repeated for several workpieces, the ILG software changes automatically the workpiece ID number, so that always only unique workpiece IDs exist.
For the specific ILP teaching process, refer to the Teaching the Bolts chapter in the ILP User Guide.
Teach
The Teach process adds one position to the selected workpiece.
Reteach
The Reteach process causes an update of the coordinates of the existing tightening positions in the workpiece/group.
During the Reteach process, it is possible to change only the existing positions in the given workpiece/group. Once reached the defined number of positions within the workpiece/group, pressing the tool trigger has no effect.
If one position is selected in the Positions list, this position will be reteached with updated x, y, z-coordinates.
If a workpiece is selected in the Positions list, all the positions in the workpiece will be retaught with updated x, y, z-coordinates.
Reteach Relative
The Reteach Relative process updates the coordinates of the existing tightening position relatively to a part target. The part target can have one dynamic tag or multiple dynamic tags.
During the Reteach Relative process, it is possible to update the coordinates of only one existing position.
