Longitudinal groove (SLOT1)

Function
You can use the "Longitudinal groove" function to mill any longitudinal groove.
The following machining methods are available:
● Mill longitudinal groove from solid material.
Depending on the dimensions of the longitudinal slot in the workpiece drawing, you can
select a corresponding reference point for the longitudinal slot.
● First predrill longitudinal groove if, for example, the milling cutter does not cut in the center
(for ShopTurn, program the drilling, longitudinal groove and position program blocks in
succession).
In this case, select the predrilling position corresponding to the "Insertion", "vertical"
parameter (see "Procedure").
Depending on the dimensions of the longitudinal slot in the workpiece drawing, you can
select a corresponding reference point for the longitudinal slot.
