2.9.2 Description of function
Sum offsets
Several sum offsets (DL numbers) can be defined per D number. This allows you to
determine, for example, workpiece-location-dependent compensation values and assign
them to a cutting edge. Sum offsets have the same effect as wear, i.e., they are added to the
compensation values of the D number. The data are permanently assigned to a D number.
Attitudes
You can define the following settings in machine data:
• Activate sum offset
• Define maximum quantity of DL data sets to be created in NCK memory
• Define maximum quantity of DL numbers to be assigned to a D number
• Define whether the sum offsets (fine/coarse) are to be saved during data backup
• Define the sum offset to be activated, if:
– A new cutting edge compensation is activated
– An operator panel reset is performed
– An operator panel start is performed
or
– The end of the program has been reached
The name is oriented to the logic of the corresponding machine data for tools and cutting
edges.
The "setup offset" and "sum offset fine" can be read and written via system variables and
corresponding OPI services.
Note
When tool management is active, a machine data can be used to define whether the sum
offset of a tool activated during a programmed tool change remains unchanged or is set to
zero.
Summary of compensation parameters $TC_DPx
The following general system variables were previously defined for describing a cutting
edge:
$TC_DP1 Tool type
$TC_DP2 Length of cutting edge
