Indexed tool
Step drills, T-slot milling cutters, side milling cutters and, in
generally, all tools that require the input of multiple length and
radius data cannot be fully defined in a single line of the tool table.
Each line of the table permits the definition of one length and one
radius.
In order to assign multiple compensation data to a tool (multiple
tool table lines), add an indexed tool number (such as T 5.1) to
an existing tool definition (T 5). Each additional line of the table
thus comprises the original tool number, a period and an index (in
ascending order from 1 to 9). The original tool table line contains
the maximum tool length; the tool lengths in the subsequent table
lines are given in descending order of their distance to the tool
holder point.
Proceed as follows to create an indexed tool number (table line):
Open the tool table
Press the Insert Line soft key
The control opens the Insert Line pop-up
window
In the Number of new lines = input field, enter
the number of lines to add
Enter the original tool number into the Tool
number input field
Confirm with OK
The control adds the additional lines to the tool
table
The Dynamic Collision Monitoring (DCM) function also
uses the length and radius data for displaying the active
tool and for collision monitoring. Incomplete or incorrect
tool definitions may lead to premature or false collision
warnings.
