Data To Steel Parameter Exercises

Vertical Step

Z-Top

In this exercise, we'll see how to limit the Z-Top and Z-Bottom values for Rough Machining.

1. Open the Vertical Step.elt file.

2. Change the Stock Type to BoxBox and change the 2nd Corner Z value to 140.
   

   

3. Open the Rough procedure and under the Tool Trajectory menu, notice that there is no limit for the Z Top and Z BottomZ Top and Z Bottom of the toolpath.
   

   

4. Save and calculate the procedure.

5. Select the Global FilterGlobal Filter and hide the Air Motions and Approach & Retract options.
   
   

   

6. Rerun the procedure and check the Z-Limits option.
   Accept the Z-Top value = 100 (maxpz).
   

   A full list of NC variable names can be found here.

7. Save and calculate the procedure.
   
   The highest Z level for milling remaining stock has been set.
   In our case, the first machining layer is a Fixed Vertical StepFixed Vertical Step down from the Z-Top height set.
   

   

8. Edit the procedure and change the Z-Top value to 66.
   Save and calculate the procedure.
   

   Using the set Z-Top value, the cutter would break due to the remaining stock above the valueremaining stock above the value.

   

9. Edit the procedure and mark the checkbox for the Check Stock Above Z-TOP parameter.

   

10. Save and calculate the procedure.
    

    The part has not been machined as stock is detected above the Z-Top value.
