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:
• → Work 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 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 feed rates of the → geometry axes
involved.
Path velocity
The maximum programmable path velocity depends on the input resolution. For example, with a resolution of 0.1
mm the maximum programmable path velocity is 1000 m/min.
