Component of the NC control for the implementation and coordination
of communication.
Outline of a -> workpiece.
See -> machine coordinate system, -> workpiece coordinate system
Central Processor Unit, -> PLC
Protected subroutine for executing a machining process that is
repeated on the -> workpiece
Using these special setting data the cycle parameter calculation can
be varied.
The available cycles are listed in menu "Cycle support" in the
"Program" operating area. Once the desired machining cycle has been
selected, the parameters required for assigning values are displayed
in plain text.
A data unit on the -> PLC which can be accessed by -> HIGHSTEP
programs.
A data unit on the -> NC: Data modules contain data definitions for
global user data. These data can be initialized directly when they are
defined.
PCIN is an auxiliary program for transmitting and receiving CNC user
data, e.g. parts programs, tool offsets, etc. via the serial interface. The
PCIN program can run under MS-DOS on standard industrial PCs.
Operating area of the control.
The control has both a self-diagnosis program as well as test functions
for servicing purposes: status, alarm and service displays.
Position and lead values can be programmed in inches in the
machining program. The control is set to a basic system regardless of
the programmable dimensional specification (G70/G71).
The cycle are programmed independent of the measuring system.
The editor makes it possible to create, modify, extend, join and import
programs/texts/program blocks.
