SINUMERIK 840D/840Di/810D Operator’s Guide HMI Advanced (BAD) – 03.04 Edition A-487
OEM
The scope for implementing individual solutions (OEM applications)
for the SINUMERIK 840D has been provided for machine
manufacturers who wish to create their own operator interface or
integrate process-oriented functions in the control.
Offset memory
Data area in the control in which tool offset data are stored.
Operator interface
The operator interface (OI) is the human-machine interface of a CNC.
It takes the form of a screen and has eight horizontal and eight
vertical softkeys.
Oriented spindle stop
Stops the workpiece spindle at a specified orientation angle, e.g. to
perform an additional machining operation at a specific position.
Oriented tool retraction
RETTOOL: If machining is interrupted (e.g. when a tool breaks), a
program command can be used to retract the tool in a user-specified
orientation by a defined distance.
Override
Manual or programmable control feature which enables the user to
override programmed feedrates or speeds in order to adapt them to a
specific workpiece or material.
P
Parameters 1. S7-300: The S7-300 uses two types of parameter:
- Parameter of a STEP7 statement
A parameter of a STEP7 statement is the address of the
operand to be processed or a constant.
- Parameter of a -> parameter block
A parameter of a parameter block determines the behavior
of a module.
2. 840D/FM-NC:
- Control operating area
- Computation parameter, can be set any number of times or
queried by the programmer for any purpose in the parts
program.
Parts program
A sequence of instructions to the NC control which combine to
produce a specific -> workpiece by performing certain machining
operations on a given -> blank.
Parts program
management
The parts program management function can be organized according
to -> workpieces. The size of the user memory determines the number
of programs and data to be managed. Each file (programs and data)
can be given a name consisting of a maximum of 16 alphanumeric
characters.
