You can select any program that is stored in your system at any time
to machine workpieces automatically.
Open the Program Manager.
Place the cursor on the program that you want to execute.
Press the "Execute" softkey.
ShopMill now switches to "Machine Auto" operating mode and
uploads the program.
Then press the "Cycle Start" key.
Workpiece machining is initiated (see also Sec. "Automatic mode".)
If the program is already open in the "Program" operating area, press
the "Execute" softkey to load the program in "Machine Auto" mode.
Then start machining of the workpiece by pressing the "Cycle Start"
key.
The "Multiple clamping" function provides optimized tool change over
several workpiece clampings. This shortens idle times because a tool
performs all machining operations in all clampings before the next tool
change is initiated.
You can use not only the surface clampings but also the "multiple
clamping" function for rotating fixture plates. For this, the machine
must have an additional rotary axis (e.g. A-axis) or a dividing unit.
Please refer to the machine manufacturer's instructions.
You can machine not only identical but also different workpieces with
this function.
The "Multiple clamping for different programs" function is a software
option.
