You can use the Stepovers tab of the Milling Feature Properties dialog to control the toolpath transitions for 2.5D milling. The type of transitions that occur at the beginning and ending of a toolpath depend on whether that portion of the toolpath is a closed or an open toolpath.
Cut type — Here you can override the feature-level Stepover type that you set on the Strategy tab for each operation. If you are using Individual rough levels, you can set the Cut type for each individual rough pass.
Non-Cutting Moves — Click this button to display the Vortex Non-Cutting Moves dialog where you can specify whether to retract and increase the feed rate on non-cutting moves for Vortex toolpaths.
Connection moves for cuts with closed ends:
Ramp type — Select the stepover style from the list.
Ramp diameter — See Ramp type.
Lead moves for cuts with open ends:
Lead In — Select Lead In to have a lead-in move and enter a Lead-in angle. The Lead-in angle applies only over the Lead-in distance, so if the Lead-in distance is 0, the Lead-in angle has no effect.
Lead Out — Select Lead Out to have a lead-out move and enter a Lead-out angle. The Lead-out angle applies only over the Lead-out distance, so if the Lead-out distance is 0, the Lead-out angle has no effect. The Lead-out angle is applied to the end of the finish pass for an open toolpath. It also applies to the last toolpath of a roughing pass if the Finish allowance is set to 0.
Cut type — Here you can override the feature-level Stepover type that you set on theStrategy tab for each operation. If you are using Individual rough levels, you can set the Cut type for each individual rough pass.
Connection moves for cuts with closed ends — There are two Ramp type options for the NT toolpaths:
Approach from outside — This option automatically adds a small lead-in whenever the tool is plunging off the stock. When you select this option, the Lead-in options are disabled. Deselect it to manually specify the lead-in as a line, arc, and/or toolpath extension.
Angle — This option supports only positive angles. The direction relative to the toolpath is automatically determined.
