SINUMERIK 802D sl/840D/840D sl/840Di/840Di sl/810D ISO Milling (PGM) - - 04.07 Edition
A key whose name appears on an area of the screen. The choice of
softkeys displayed is adapted dynamically to the operating situation.
The freely assignable function keys (softkeys) are assigned to
functions defined in the software.
Software limit switches define the limits of the travel range of an
axis and prevent the slide contacting the hardware limit switches.
Two pairs of values can be assigned per axis and activated
separately via the --> PLC.
The spindle functionality is a two--level construct:
1. Spindles: Speed--controlled or position--controlled spindle drives,
analog
digital (SINUMERIK 840D)
2. Auxiliary spindles: Speed--controlled spindle drives without actual
position sensor, e.g. for power tools. "Auxiliary spindle" function
package, e.g. for power tools.
Using the spline interpolation function, the control is able to
generate a smooth curve from just a small number of specified
interpolation points along a setpoint contour.
Standard cycles are used to program machining operations which
repeat frequently:
• For drilling/milling
• For measuring tools and workpieces
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 plaintext.
Block prefixed by "N" containing information for a machining step
such as a position parameter.
A sequence of instructions of a --> part program which can be called
repeatedly with different initial parameters. A subroutine is called
from within a main program. Every subroutine can be locked against
unauthorized export and viewing (with MMC 102/103). --> Cycles
are a type of subroutine.
