Saving tool data

In the NC program it is possible to permanently modify certain information for the current tool, i.e. save it after the tool is deselected.

This is done using what is known as additional tool parameters (V.G.WZ_AKT.P[i]). For example, these parameters can save wear data or measured values of the currently active tool during program runtime. The data is then written back to the external tool management system and saved there when a new tool record (Dxx) is selected or when a tool is deselected (D0).

If an active tool is not deselected by program end and if the channel-specific parameter (P-CHAN-00103) is set accordingly, the data of the last tool used is transferred back implicitly to the external tool management system and written there at the next program start.

T/D number

In addition, when a tool record is selected, the T and D numbers of the tool last used are transferred back to the external tool management system.

Programing Example

NC program with tool requesting

In the example below, various tool data items (life parameters and tool parameters) are written by the CNC and returned to the external tool management system.
