Barpull Cycle

This cycle is one of the new extended style EZCAM cycles and used when bar-pull or bar-feed operations are required. When selected, the cycle opens a small dialog that displays the bar-pull specific settings only. Once finished there, you will normally use the "Work Step Data" button to continue to the regular machining dialogs to define all other parameters like the tool/turret number that should be used. To edit the bar-pull specific settings, simply double-click the corresponding Work Step in the Selection List Box. To edit settings on the regular "Work Step Data" dialog you can also use the Work Step Data command from the Machining menu. Please note that toolpath verification only shows the center toolpath.

X Rapid Diameter (Xr)

The diameter value specified here defines the X axis position to were the tool will be positioned at rapid feedrate before moving down to X0.0.

Z Pull Start Position (Zs)

This is the absolute initial Z axis position where the tool is positioned before retracting the pull distance.

Barpull Cycle Movement Sequence:

  1. Tool (stopper) rapids to the position specified by the X Rapid Diameter (Xr) and Z Pull Start Position (Zs) settings (Step1).

  2. Tool moves to the center of the X axis (Step2).

  3. Tool feeds out the Zp pull amount (Step3).  

  4. Tool moves back to tool change position.

 Important Post-Processor Information

When creating the NC code, the Barpull cycle directly calls "User Cycle-18" section from the post-processor. This section is specially customized and was not available in post-processor versions prior to V13. If your current post-processor does not support Barpull or you need further customization, contact EZCAM support and request an update proposal.
