They consist of several components (geometry, wear). The control computes the
components to a certain dimension (e.g., overall length 1, total radius). The respective
overall dimension becomes active when the offset memory is activated.
The way in which these values are computed in the axes is determined by the tool type and
the current plane G17, G18, G19.
• Tool type
The type determines which geometry data are needed and how they are calculated (drill or
milling tool or turning tool).
• Cutting-edge position
Tool parameters
The following section "List of tool types" describes the individual tool parameters on the
display. The relevant tool parameters must be entered in the entry fields with "DP...".
Notice
Values that have been entered once in the offset memory are included in the processing for
each tool called.
