Control is switched off and then switched on again.
After loading the cycles it is always necessary to carry out a Power
ON.
Operating area of the control.
Sequence of instructions to the control.
The highest traversing speed of an axis. It is used to move the tool
from rest to the -> workpiece contour or retract the tool from the
contour.
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.
Calculation parameter. The programmer of the -> parts program can
assign or request the values of the R parameter as required.
Component of a -> frame which causes axis-specific alterations in the
scale.
For the purpose of data input and output, one serial RS-232 interface
(similar to European Standard V.24) (RS232) is provided on the MMC
module MMC 100 and two RS-232 interfaces on the MMC modules
MMC 101 and MMC 102. 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.
