8.4.7 Longitudinal groove (SLOT1)
Function
You can use the "Longitudinal groove" function to mill any longitudinal groove.
The following machining methods are available:
● Mill longitudinal slot 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.
● Predrill longitudinal groove in the center first if, for example, the milling cutter does not cut
in the center (program the drilling, longitudinal groove and position program blocks in
succession).
In this case, select "inner left" as reference point. This point corresponds to the predrilling
position.
Clamping the spindle
For ShopTurn, the "Clamp spindle" function can be set up by the machine manufacturer.
Machine manufacturer
Please refer to the machine manufacturer's specifications.
Longitudinal slot with the width of the tool
When milling a longitudinal slot, which is located in parallel with the spindle axis, and which
should be machined with the width of the tool, then the clamping remains active after
insertion in order to achieve more accurate results.
The cycles identify this special case and do not cancel clamping after insertion if the
following secondary conditions are fulfilled.
After machining, the clamping in the cycles is canceled again.
Supplementary conditions
● Finishing longitudinal slot with width = tool diameter
● Roughing longitudinal slot with (width - 2 * finishing allowance) = tool diameter
