SINUMERIK 802D sl/840D/840D sl/840Di/840Di sl/810D ISO Milling (PGM) -- 04.07 Edition
Asynchronous
subroutine
• A part program that can be started asynchronously (or
independently) by means of an interrupt signal (e.g. ”High--speed
NC input” signal) while the part program is active (SW package 3
and earlier).
• A part program that can be started asynchronously (or
independently) of the current program status by means of an
interrupt signal (e.g. ”High--speed NC input” signal) (SW package
4 and later).
Automatic Control system operating mode (block--sequential to DIN): Mode in
NC systems in which a --> part program is selected and
continuously executed.
Auxiliary functions Auxiliary functions can be used to pass --> parameters to the -->
PLC in --> part programs, triggering reactions there which are
defined by the machine manufacturer.
Axes CNC axes are classified according to their functional scope as:
• Axes: Interpolative path axes
• Positioning axes: Non--interpolative infeed and positioning axes
with axis--specific feedrates; axes can move across block limits.
Positioning axes need not be involved in workpiece machining as
such and include tool feeders, tool magazines, etc.
Axis address See --> axis identifier
Axis identifier In compliance with DIN 66217, axes are identified as X, Y and Z for
a right--handed rectangular --> coordinate system.
--> Rotary axes rotating around X, Y, Z are assigned the identifiers
A, B, C. Additional axes, which are parallel to those specified, can
be identified with other letters.
Axis name See --> axis identifier
Axis/spindle
replacement
An axis/spindle is permanently assigned to a particular channel via
machine data. This MD assignment can be ”undone” by program
commands and the axis/spindle then assigned to another channel.
