Delete last cutting edge
Description
This function block deletes the last cutting edge for the selected tool and, if necessary,
initializes the display parameters with the data of the last available cutting edge. The last
cutting edge of a tool can be deleted only if the tool has more than one cutting edge.
If the last cutting edge can be deleted, the D No. is declared unassigned via the TO memory
management and the setup data of the tool updated. If a cutting edge that was displayed on
the NC screen is deleted, the D No. of the new last cutting edge is entered into the R para-
meter R999 for indirect addressing, the display parameters initialized with the data for this
cutting edge and the block function terminated.
In the case of an error - deletion of the last cutting edge is not permissible - a message
appears on the NC screen and the block function is terminated.
