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.
Overall reset
In the event of an overall reset, the following memories of the → CPU are deleted:
● → Working memory
● 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 statements 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 given a name consisting of a maximum of 24 alphanumeric
characters.
Path axis
Path axes include all machining axes of the → channel that are controlled by the → interpolator
in such a way that they start, accelerate, stop, and reach their end point simultaneously.
Path feedrate
Path feed affects → path axes. It represents the geometric sum of the feedrates of the
→ geometry axes involved.
