To Create a Helical Exit Motion
Helical Exit motions let you make the tool exit an Automatic Cut motion (or another exit motion) along a helix. The EXIT_ANGLE parameter defines the angle of the helical exit motion. PULLOUT_DIST controls the height of the helical exit motion.
1. Choose Helical Exit from the drop-down list in the Customize dialog box, and click Insert.
2. The Helical Lead Out dialog box opens.
3. Edit the Tool Motion parameters, if desired, using the Feed, Spindle, and Coolant buttons in the top portion of the box.
4. If this is a 4- or 5-Axis NC sequence, you can specify the tool axis orientation using the Specify Axis button.
5. Select the arrow direction using the Left and Right option buttons. The arrow indicates the exit direction.
6. Edit the Exit Angle, Pullout Distance, Normal Lead Step, and Lead Radius values in the corresponding text boxes, if needed. If the Use Default checkbox underneath a parameter text box is selected, the system will automatically assign a value to this parameter. If you clear the checkbox, you will be able to edit the parameter value in the text box.
7. The Preview button allows you to preview the tool motion defined. Click OK if satisfied, Cancel—to quit creating the tool motion.
