Rigid tapping can be drilled with the help of this function. When the
rigid tapping function is used, interpolation of the spindle acting as a
rotary axis and the drilling axis ensures that threads are cut exactly to
the end of the drilling depth, e.g. tapped blind hole (precondition:
spindle is operating in axis mode). -> CYCLE84
Component of a -> frame which defines a rotation of the coordinate
system through a specific angle.
Component of a -> frame which causes axis-specific alterations in the
scale.
For the purpose of data input and output,
one serial V24 (RS232) interface is provided on the MMC module
MMC100 and two V24 interfaces on the MMC modules MMC101 and
MMC102. It is possible to load and save machining programs, cycles
as well as manufacturer and user data via these interfaces.
Operating area of the control.
Data which provide the NC control with information on properties of
the machine tool in a way defined by the system software.
Standard cycles are provided for machining operations which are
frequently repeated:
Cycles for drilling/milling applications
Cycles for turning applications (SINUMERIK FM-NC)
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 sequence of instructions of a -> part program which can be called
repetitively with various defining parameters. The subroutine is called
from a main program. Every subroutine can be protected against
unauthorized read-out and display. -> Cycles are a type of subroutine.
