Tool radius R
You can enter the tool radius R directly.
Delta values for lengths and radii
Delta values are offsets in the length and radius of a tool.
A positive delta value describes a tool oversize (DL, DR, DR2>0). If you
are programming the machining data with an allowance, enter the
oversize value in the TOOL CALL block of the part program.
A negative delta value describes a tool undersize (DL, DR, DR2<0). An
undersize is entered in the tool table for wear.
Delta values are usually entered as numerical values. In a TOOL CALL
block, you can also assign the values to Q parameters.
Input range: You can enter a delta value with up to ± 99.999 mm.
Entering tool data into the program
The number, length and radius of a specific tool is defined in the TOOL
DEF
block of the part program.
8 To select tool definition, press the TOOL DEF key.
8 Tool number: Each tool is uniquely identified by its tool
number.
8 Tool length: Compensation value for the tool length
8 Tool radius: Compensation value for the tool radius
Example
Delta values from the tool table influence the graphical
representation of the tool. The representation of the
workpiece remains the same in the simulation.
Delta values from the TOOL CALL block change the
represented size of the workpiece during the simulation.
The simulated tool size remains the same.

In the programming dialog, you can transfer the value for
tool length and tool radius directly into the input line by
pressing the desired axis soft key.
