Function
The cylinder surface transformation is required in order to
•
Longitudinal grooves on cylindrical bodies,
•
Transverse grooves on cylindrical objects,
•
Grooves with any path on cylindrical bodies.
The cylinder peripheral surface transformation is a software option.
The path of the grooves is programmed with reference to the
unwrapped, level surface of the cylinder. The slot can be programmed
as a line/circle contour, via drilling or milling cycles or with the contour
milling function (free contour programming).
There are two variants of cylinder surface transformation, i.e.
•
Slot side compensation OFF
•
Slot side compensation on (path milling only)
When slot side compensation is
deactivated, any type of slot with
parallel sides can be machined if
the tool diameter equals the slot
width.
The slot sides are not parallel if the
slot width is larger than the tool
diameter.
The slot contour is programmed for machining purposes.
