11.8 Working with Cutting Data
Ta b l e s
Note
Applications
In cutting data tables containing various workpiece and cutting
material combinations, the TNC can use the cutting speed V
C
and the
tooth feed
Z
to calculate the spindle speed S and the feed rate F. This
calculation is only possible if you defined the workpiece material in the
program and various tool-specific features in the tool table.
The TNC must be specially prepared by the machine tool
builder for the use of cutting data tables.
Some functions or additional functions described here
may not be provided on your machine tool. Refer to your
machine tool manual.

Before you let the TNC automatically calculate the cutting
data, the tool table from which the TNC is to take the tool-
specific data must be first be activated in the Test Run
mode (status S).
