SINUMERIK 840D/840Di/810D Operator's Guide HMI Advanced (BAD) – 03.04 Edition
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.
Data area in the control in which tool offset data are stored.
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.
Stops the workpiece spindle at a specified orientation angle, e.g. to
perform an additional machining operation at a specific position.
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.
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.
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.
A sequence of instructions to the NC control which combine to
produce a specific -> workpiece by performing certain machining
operations on a given -> blank.
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.
