Option (AFC)
Defining the AFC basic settings
You make the control settings for the TNC feed rate control in the table
AFC.TAB, which must be saved in the root directory TNC:\.
The data in this table are default values that were copied during a
teach-in cut into a file belonging to the respective program and serve
as the basis for control. The following data are to be defined in this
table:
Column Function
NR Consecutive line number in the table (has no further
functions)
AFC Name of the control setting. You enter this name in the
AFC
column of the tool table. It specifies the
assignment of control parameters to the tool.
FMIN Feed rate at which the TNC is to conduct a shutdown
response. Enter the value in percent with respect to
the programmed feed rate. Input range: 50 to 100%
FMAX Maximum feed rate in the material up to which the TNC
can automatically increase the feed rate. Enter the
value is in percent with respect to the programmed
feed rate.
FIDL Feed rate for traverse when the tool is not cutting (feed
rate in the air). Enter the value is in percent with
respect to the programmed feed rate.
FENT Feed rate for traverse when the tool moves into or out
of the material. Enter the value in percent with respect
to the programmed feed rate. Maximum input value:
100%
OVLD Desired reaction of the TNC to overload:
„
M : Execution of a macro defined by the machine tool
builder
„
S : Immediate NC stop
„
F : NC stop if the tool has been retracted
„ E : Just display an error message on the screen
„ - : No overload reaction
The TNC conducts a shutdown response if the
maximum spindle power is exceeded for more than
one second and at the same time the feed rate falls
below the minimum you defined.
POUT Spindle power at which the TNC is to detect when the
tool exits the workpiece. Enter the value in percent
with respect to the recorded reference load.
Recommended value: 8%
