SINUMERIK 840D/840Di/810D Programming Guide Cycles (PGZ) – 11.02 Edition
Numerical control It incorporates all the components of the of the
machine tool control system: -> NCK, -> PLC, -> MMC, -> COM.
Note CNC (computerized numerical control) would be a more
appropriate description for the SINUMERIK 810D or 840D.
Numeric Control Kernel: Components of the NC control which
executes -> parts programs and essentially coordinates the
movements on the machine tool.
Stops the workpiece spindle with a specified orientation angle, e.g. to
perform an additional machining operation at a specific position.
This function is used in several drilling cycles.
840D:
- Operating area of the control unit
- Computation parameter, can be set or scanned in the
program at the discretion of the programmer for any
purposes he may deem meaningful.
A sequence of instructions to the NC control which combine to
produce a specific -> workpiece by performing certain machining
operation on a given -> blank.
The parts program management function can be organized according
to -> workpieces. The number of programs and data to be managed
determine the size of the user memory. Each file (programs and data)
can be given a name consisting of a maximum of 24 alphanumeric
characters.
Programming device
Programmable logic control: -> Programmable logic control.
Component of the -> NC control: A control which can be programmed
to control the logic on a machine tool.
A coordinate system which defines the position of a point on a plane in
terms of its distance from the origin and the angle formed by the
radius vector with a defined axis.
