PI service: DELECE
Function: Delete a tool cutting edge
If the T number of an existing tool is specified in parameter “T number” in the PI service, then a cutting edge is
deleted for this particular tool (in this case, parameter “D number” (number of cutting edge to be created) has a
value range of 00001–00009). If a positive T number is specified as a parameter and the tool for the T number
entered does not exist, then the PI service is aborted. If a value of 00000 is entered as the T number (model of
absolute D numbers), then the D number values can range from 00001-31999. If the specified cutting edge does
not exist, then the PI service is aborted in both cases.
PI service: DELETO
Function: Delete tool
Deletes the tool assigned to the transferred T number with all cutting edges (in TO, in some cases TU, TUE and
TG (type 4xx), TD and TS blocks).
