Data range in the control in which the tool offset data are stored.
An operating concept on a SINUMERIK control. The operating modes
-> Jog, -> MDA and -> Automatic are defined.
Stops the workpiece spindle with a specified orientation angle, e.g. to
perform an additional machining operation at a specific position.
RETTOOL: If machining is interrupted (because of tool breakage, for
example), a program command can be used retract the tool with a
defined orientation by a defined path.
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: A distinction is made between 2 types of parameters:
- Parameters of a STEP 7 instruction
A parameter of a STEP 7 instruction is the address of the
operand to be processed or a constant.
- Parameters of a -> parameter block
A parameter of a parameter block determines the behavior of
a module.
2. 840D/FM-NC:
- Control operating area
- Arithmetic parameter for which the programmer of the parts
program can assign or request values as required in the
program.
A sequence of instructions to the NC control which combine to
produce a specific -> workpiece. Likewise, performing a certain
machining operation on a specific -> blank.
Part programs can be organized according to -> workpieces. The size
of the user memory determines the number of programs and the
amount of data that can be managed. Each file (programs and data)
can be assigned a name comprising up to 24 alphanumeric
characters.
Path axes are all the machining axes in the -> channel which are
controlled by the -> interpolator so that they start, accelerate, stop and
reach their end positions simultaneously.
