Machining information

Tool selection and turret assignment list

This function is also available on machines with a tool
magazine. The control uses the magazine list instead of
the turret list.
The tool selection is determined by:
Machining direction
Contour to be machined
Machining sequence
Setting of the machining parameter Type of tool access
Machine parameter settings
You can influence the type of tool access parameter
both with the machining parameters and with the wd
machine parameter (no. 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.
Further information:
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 machine parameter defaultG59 (no.
602022), TURN PLUS automatically calculates the
required datum shift for the workpiece and activates it
with G59.
Further information:
To calculate the datum shift, TURN PLUS takes the
following values into account:
Length Z (description of workpiece blank)
Ov.size K (description of workpiece blank)
Edge of chuck Z (description of chucking equipment
and machining parameters)
Chuck jaw reference B (description of chucking
equipment and machining parameters)
Multipoint tools and manual tool change holders are
used by the AWG submode only if they are already
entered in the turret list of the NC program.
