Use the Separate first lead in area to specify a first lead in move that is different from the subsequent lead in moves. The settings in this page are not available for Vortex toolpaths.
Separate first lead in — Select this option to specify a different first lead in move. This offer similar functionality as the Lead ins area, but applies it only to the first lead in move.
This example uses a Lead in and Lead out of Surface normal arc.
Use a separate first lead in deselected:
A First lead in of Surface normal arc with a Distance of 0, an Angle of 90 and a Radius of 5.
Use a separate first lead in selected:
A First lead in of Ramp (where the ramp follows the toolpath).
Choice — Select the type of move to use at the start of the toolpath.
Linear move — Enter the distance to extend the Separate first lead in move before the cutting move starts. The distance is the length of the linear tangential move between the arc and the cutting portion of the toolpath.
Distance of 0.
A First lead in of Surface normal arc with a Distance of 0, an Angle of 90 and a Radius of 5.
Distance of 10.
Angle — Enter the angle of the Separate first lead in move relative to the first toolpath segment. For arcs, this is the angle spanned by the arc. For lines, it is the orientation relative to the cutting move.
Angle of 90
.
A First lead in of Surface normal arc with a Distance of 0, an Angle of 90 and a Radius of 5.
Angle of 180.
For a First lead in of Straight and Angle of 0.
Angle of 90.
Radius — Enter the radius of the Separate first lead in arc move.
Radius of 5.
A First lead in of Surface normal arc with a Distance of 0, an Angle of 90 and a Radius of 5.
Radius of 10.
Length — Enter the length to extend the Separate first lead in move before the cutting move starts. This option is available only for a Choice of: Extended move, Boxed, and Straight.
Ramp Options — Click to display the First Lead in Ramp Options dialog where you can specify how the tool ramps into the stock. This is the same as the Lead in Ramp Options dialog, except there is no 2nd Choice tab. This is available only when you select a Choice of Ramp.
Gouge check — Select this option for PowerMill to gouge-check all leads and links.
— Click to copy the Separate first lead in values to the Separate last lead out tab.
