Machining type
You can select the machining mode (roughing, finishing, or chamfer) for path milling. If you
want to "rough" and then "finish", you have to call the machining cycle twice (Block 1 =
roughing, Block 2 = finishing). The programmed parameters are retained when the cycle is
called for the second time.
It is also possible to choose between machining the contour with a cutter radius offset or
traversing on the center-point path.
Slot side compensation
When you mill a contour on the peripheral surface (peripheral machining surface C), you can
work with or without a slot wall compensation.
● Slot side compensation off
ShopTurn creates slots with parallel walls when the tool diameter is equal to the slot
width. If the slot width is larger than the tool diameter, the slot walls will not be parallel.
● Slot side compensation on
ShopTurn creates slots with parallel walls also when the slot width is larger than the tool
diameter. If you want to work with a slot wall compensation, you must not program the
contour of the slot, but instead the imagined center path of a bolt inserted in the slot
whereby the bolt touches both walls. Parameter D is used to specify the slot width.
Procedure
1. The part program or ShopTurn program to be processed has been
created and you are in the editor.
2. Press the "Milling" softkey.
3. Press the "Contour milling" and "Path milling" softkeys.
The "Path Milling" input window opens.
