Deburring 4

1. In the Tool axis control tab, set the Machining type to 5 axis (simultaneous).
   
   Note the other options:

   • 3 Axis – No tilting.

   • 4 Axis (Rotary) – the tool is always orthogonal and points to the rotary axis.

   • 4+1 Axis (Autotilt) – 4 axes simultaneous + one axis set with a fixed angle to a specified axis. Optional – point tool to rotary axis.

   • 3+2 Axis – tool kept with a fixed orientation as much as possible, with smooth transition between orientations. Collision avoidance can force a 5 axes simultaneous motion.

   • 5 Axis (Simultaneous) – full 5 axes.

2. Set the Strategy to Normal to contour. For initial orientation (as seen in the right hand image), the system tries to keep the tool orthogonal to the edge in a bi-vector orientation between the two surfaces of the edge. Collision control may change this orientation.
   

3. Collision detection is always activated. It will change the tool orientation to Avoid. The image below shows the clearance values to the different tool portions.
   

4. Execute the procedure and use the Navigator to examine the results. For some of the edges, the tool approaches in a bad orientation and gouges the part. This occurs at times since the system is not always able to find a collision-free orientation.
