Optimized Entry Mode

1. Change the Entry Mode to Optimized and set the Ramp Angle to 20.
   

2. Save and calculate the procedure.

   In this mode, Cimatron compares the machining length between the two entry options:

   1. Plunging in the material (calculated according to the ramping motion).
   2. Plunging in the air and making a slotting pass.

   In this example, the Ramp Angle is 20 degrees and, therefore,Cimatron uses the Plunge option.

3. Change the Ramp Angle to 10.
   
   The ramping motion becomes longer and the system prefers to plunge in the air and then make slotting passes.

4. Open the procedure, select the Boundary parameter in the Geometry tab and remove the boundary.
   

5. Save and calculate the procedure.
   
   The tool plunges outside the material and then makes a slotting motion towards the pocket start point. The lower layers are machined using a plunging motion due to the step.
   
   The lower layer does not use a helical plunge as there is not enough room for the cutter to use this method. Instead, a slotting plunge method is used.
