4.6 Erosion Tables
The spark erosion process is influenced by process variables called
erosion parameters. You can enter the erosion parameters for a
machining sequence in erosion tables for the TNC 406/416.
For example, you can create a separate erosion table for each
combination of electrode and workpiece material.
All parameters are then clearly grouped in this table. The TNC can
access the parameters for a particular machining sequence.
Using erosion tables in a program
If you want to work with erosion tables in a program, you must copy
Cycle 1 (GENERATOR) into the program (see „Cycle 1 GENERATOR”
on page 133). In this cycle you declare what erosion table you are
working with.
Working without an erosion table
It is also possible to work without an erosion table. In this case the
TNC stores the erosion parameters in the Q parameters Q90 to Q99
(see „Preassigned Q parameters” on page 202). Your machine manual
provides more information on these Q parameters.
Ready-to-use erosion tables
The machine builder can prepare erosion tables and store them in the
TNC’s ROM. Proceed as follows if you want to work with these
erosion tables:
8 Press the PGM NAME key in the PROGRAMMING AND EDITING
mode of operation.
8 Press the ROM soft key.
The machine tool builder can give you additional information on these
erosion tables.
The machine tool builder can define the erosion tables as
required. He may also define additional parameters that
are not mentioned in your TNC manual. Refer to your
machine tool manual.
