Lead in and Lead out
This option is used in several machining cycles, with different purposes and behaviours.
Please use the tree on the right side of the screen.
Cycles: Straight Cut, Taper cutting / 4 Axes cnt / cnt, 4 Axes elt / elt
Definition for Straight Cut, Taper cutting
These parameters allow you to add overlengths and arcs on the approach and return of the wire.
Only the lead in parameters are explained; the lead out parameters definitions are exactly the same.
Lead in overlength (A)
A positive value extends the toolpath on the first element of the profile and a negative value shortens it. If the first element is an arc, the overlength is circular. This is generally used when the machining begins on an outside corner.
Lead in arc radius (B)
Quarter of circle added before the first profile element, tangent to him. If the lead in extension is used, the lead in arc radius is positioned before it. This radius must be greater than the wire radius.
Overlength on radius (C)
If a lead in arc radius is defined, you can add a linear overlength before it. You can choose between:
Auto: the overlength on the radius is calculated automatically relative to the threading point
Manual: type in the overlength on the radius.
Overlength on lead in radius (C)
If the choice is 'Manual', type in the value you want.
