Log file

The TNC stores various pieces of information for each machining
step of a teach-in cut in the

.H.AFC2.DEP file.

is the name of the NC program for which you have recorded the

teach-in cut. During control, the TNC updates the data and makes

various evaluations. The following data are to be saved in this table:

Column

Function

NR

Number of the machining step

TOOL

Number or name of the tool with which the

machining step was made

IDX

Index of the tool with which the machining step

was made

SNOM

Nominal spindle speed [rpm]

SDIF

Maximum difference of the spindle speed in % of

the nominal speed

LTIME

Machining time for the teach-in cut

CTIME

Machining time for the control cut

TDIFF

Time difference in % between the machining time

during teach-in and control

PMAX

Maximum recorded spindle power during

machining. The TNC shows the value as a percent

of the spindle’s rated power.

PREF

Reference load of the spindle. The TNC shows the

value as a percent of the spindle’s rated power.

FMIN

Smallest occurring feed factor. The TNC shows the

value as a percentage of the programmed feed rate

OVLD

Reaction by the TNC to overload:

M: A macro defined by the machine tool builder

has been run
S: Immediate NC stop was conducted
F: NC stop was conducted after the tool was

retracted
E: An error message was displayed
-: There was no overload reaction

BLOCK

Block number at which the machining step begins
