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.

Select the tool definition: Press the TOOL DEF key

Tool number

: Each tool is uniquely identified by its tool

number

Tool length

: Compensation value for the tool length

Tool radius

: Compensation value for the tool radius

Example

DR<0

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.
If the tool table TOOL.T is active, use a TOOL DEF block to

preselect the tool. The machine manual provides further

information.
