Start and Final Overlengths

Cycles: All Manual Cycles

Definition

These commands allow you define overlengths for the input and the output of the tool in the material. As from V6.11, the overlengths take into consideration the shape of the profile.

Start overlength (1)

The first element of profile is lengthened by the defined value. If the value is negative, the profile is shortened.

  • In case of open profile, the overlength is the same nature of the first element, linear for a segment and circular for an arc, by respecting the tangency.

  • In case of closed profile, the start overlength is tangent to the last element.

→ Consequently, if the profile starts on an arc and ends on a segment, the start overlength is linear, as shown on the example.

Final overlength (2)

Same principle as Start overlength, Final overlength generates the toolpath tangent to the first element.

→ Consequently, if the profile starts on an arc and ends on a segment, the end overlength is circular, as shown on the example.
