5.5.3 Rectangular spigot
The "Rectangular spigot" function is used when you want to mill
various rectangular spigots.
You can select from the following shapes with or without a corner
radius:
Rectangular spigot
In addition to the required rectangular spigot, you must also define a
blank spigot, i.e. the outer limits of the material. The tool moves at
rapid traverse outside this area. The blank spigot must not overlap an
adjacent blank spigots. ShopTurn automatically centers the finished
spigot within the blank.
The spigot is machined using only one infeed. If you want to machine
the spigot using multiple infeeds, you must program the "Rectangular
spigot" function several times with a reducing finishing allowance.
