7.3 Machining information
Tool selection, turret assignment
The tool selection is determined by:
 Machining direction
 Contour to be machined
 Machining sequence
 Machine parameter settings, e.g. "Type of tool access" (602001)
If the ideal tool is not available, TURN PLUS
 First looks for a replacement tool,
 Then for an emergency tool.
If necessary, TURN PLUS adapts the machining cycle to the
requirements of the replacement or emergency tool. If more than one
tool is suitable for a machining operation, TURN PLUS uses the
optimal tool. If no tool is found by TURN PLUS, select the tools
manually.
The Mount type distinguishes between different tool holders (see
"Tool editor" in the User's Manual). TURN PLUS checks whether the
mount type in the tool holder description and the mount type in the
turret pocket description are the same.
Depending on the setting of the "Zero point shift" machine
parameter (602022), TURN PLUS automatically calculates
the required zero point shift for the workpiece and
activates it with G59 (see "List of user parameters" in the
User's Manual).
To calculate the zero point shift, TURN PLUS takes the
following values into account:
 Workpiece length Z (description of workpiece blank)
 Oversize K (description of workpiece blank)
 Edge of chuck Z (description of chucking equipment and
machining parameters)
 Edge of chuck B (description of chucking equipment and
machining parameters)
Multipoint tools and manual tool change holders are used
by AWG only if they are already entered in the turret list of
the NC program.
