Purpose
|
|
In this chapter the operations will be fine tuned, using manual teach and manipulate functionality to modify the operations and transitions between the operations. Different functions, strategies and optimization algorithms are available. A few of them are taught here.
|
|
|
Operations, or parts of operations, are being modified and simulated to see the effect.
|
|
|
Steps
|
|
|
Be sure to save your changes frequently.
|
|
|
1
|
Interpolations
|
1.1
|
|
Run a partial simulation at the side of the workpiece to see the normal position of the laser head change while moving along the path.
|
1.2
|
|
Create a normal vector interpolation for the just simulated range. Run the simulation again to notice that the laser head normal orientation does not change while moving along the path.
|
1.3
|
|
For a smoother rotation of the laser head, create an interpolation over the singularity optimized axis.
|
|
|
2
|
Optimize the toolpath orientation
|
2.1
|
|
Activate the Collision analysis. Pick the approach position of the circle on the workpiece outer flange. Open the Teach panel and step through the circle operation. Notice that the laser head is in collision with the workpiece at parts of the operation.
|
|
2.2
|
|
Optimize the circle toolpath orientation. Step to the lead in position. In the Teach panel, change the head axis rotation to A = -180 deg and B = 10 deg. Step again through the operation to see a collision free motion.
|
2.3
|
|
Toolpath positions can also be modified individually. Select the position you need to modify. Instead of the Teach panel, also the manipulator can be used to change the position and / or orientation.
|

3
|
Minimize laser head motion
|
3.1
|
|
Open the Active program dashboard. Play a partial simulation on the operation group of the four holes.
Open the tech tab Regshape and modify the approach and retract distance for the group. Then change the approach distance for the first operation of the group and the retract distance for the last operation of the group. Re-run the simulation to see the result.
|
|
|
4
|
Insert auxiliary positions
|
4.1
|
|
Activate the Collision analysis, if not done already. Run a partial simulation between the operations of the four holes and the outer contour operation. Notice that the laser head collides with the workpiece during the transition between operations.
Move the manipulator to a collision free position and insert an extra auxiliary position in between the operations.
|
|
|
5
|
Workpiece offset
|
5.1
|
|
It may be possible that the program has been computed on the 'wrong' side of the workpiece. This can be be corrected easily.
Open the Active program dashboard and the tech tab Toolpath calculation. Search for the container Local offset and set a value for the Sheet offset attribute. Notice that the effect on the toolpath.

|
Technology attributes
|
6.1
|
|
Open the Active program dashboard and the tech tab Technology base. verify and modify where needed the different technology attributes.
