Starting program
execution from an
operating area
The program is loaded in "Machine Auto" mode and "Automatic" mode
is activated on the machine control panel.
Cycle Start
Press the "Cycle Start" key.
The program is started and executed from the beginning. However,
the interface of the previously selected operating area remains on the
screen.
3.2 Running-in a program
When running-in a program, ShopTurn can interrupt the machining of
the workpiece after each program block, which triggers a movement o
auxiliary function on the machine. In this way, you can control the
machining result block-by-block during the initial run-through of a
program on the machine.
For drilling and pocket milling, the entire machining process and a
plane machining process (respectively) are compiled into one block.
Drilling and pocket machining processes can be split up into single
blocks using the "Single block fine" function. In addition, machining at
this setting is stopped after each individual contour element of a
contour.
Single block
Load a program in "Machine Auto" mode (see Sec.
"Starting/stopping program execution").
Single Block
Press the "Single Block" key.
Cycle Start
Press the "Cycle Start" key.
The first block of the program is executed. Then the machining stops.
In the channel status line, the text “Stop: Block in single block ended"
appears.
Cycle Start
Press the "Cycle Start" key.
The next block of the program is executed. Then the machining stops
again.
Single Block
Press the "Single Block" key again, if the machining is not
supposed to run block-by-block. (The key is then deselected
again).
If you now press the "Cycle Start" key again, the program is executed
to the end without interruption.
