General information (turning)
Functionality
During program creation for the workpiece machining, you do not have to take tool lengths or cutting radius into
consideration. You program the workpiece dimensions directly, e.g. according to the drawing.
The tool data must be entered separately in a special data area.
In the program, you will merely call the required tool with its offset data. The control system performs the required path
compensations based on the data to create the described workpiece.
See the following illustration for machining a workpiece with different tool dimensions:
Tool T (turning)
Functionality
The tool selection takes place when the T word is programmed. Whether this is a
or only a
is
defined in the machine data:
● A tool change (tool call) takes place directly with the T word (e.g. typical for tool turrets on turning machines)
or
● The change takes place after the preselection with the T word by an additional instruction
If a certain tool was activated, it remains stored as an active tool even beyond the end of the program and after switching
off/switching on the control system.
If you change a tool manually, input the change also in the control system so that the control system 'knows' the correct
tool. For example, you can start a block with the new T word in MDA mode.
