Operating mode
An operating concept on a SINUMERIK control. The operating modes -> Jog, -> MDA and ->
Automatic are defined.
Oriented spindle stop
Stops the workpiece spindle with a specified orientation angle, e.g. to perform an additional
machining operation at a specific position.
Oriented tool retraction
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.
Overall reset
In the event of an overall reset, the following memories of the → CPU are deleted:
• -→ RAM
• Read/write area of → load memory
• → System memory
• → Backup memory
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.
Part program
Series of instructions to the NC that act in concert to produce a particular → workpiece.
Likewise, this term applies to execution of a particular machining operation on a given → raw
part.
Part program block
Part of a → part program that is demarcated by a line feed. There are two types: → main
blocks and → subblocks.
Part program management
Part program management can be organized by → 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 axis
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.
